Groats (or in some cases, "berries") are the hulled kernels of various cereal grains, such as oats, wheat, rye, and barley. Groats are whole grains that include the cereal germ and fiber-rich bran portion of the grain, as well as the endosperm (which is the usual product of milling).

Groats can also be produced from pseudocereal seeds such as buckwheat.

Culinary uses

[edit]

Groats are nutritious but can be difficult to chew, so they are often soaked before cooking. Groats are used as the main ingredient in soup, porridge, bread, and vegetable-based milk.

Groats of many cereals are the basis of kasha, a porridge-like staple meal of Eastern Europe and Eurasia. In North America, kasha or kashi usually refers to roasted buckwheat groats in particular.

In North India, cut or coarsely ground wheat groats are known as dalia, and are commonly prepared with milk into a sweet porridge or with vegetables and spices into salty preparations.[1]

In Yemen, boiled groats are eaten as a hot breakfast cereal, known as harish, and topped with clarified butter (samneh), or with honey.[2] In Palestine and Syria, the same dish is known locally as ğarīš (Arabic: جَرِيش), which may also refer to the farinaceous dish of semolina.

Parboiled and cut durum wheat groats, known as bulgur, are an essential ingredient of many Middle Eastern dishes such as mansaf and tabbouleh.

Groats are also used in some sausages, such as black puddings. A traditional dish from the Black Country in England is called groaty pudding (not to be confused with groats pudding). Groaty pudding is made from soaked groats, leeks, onions, beef, and beef stock, baked for up to 16 hours. It is a traditional meal on Guy Fawkes Night.[3]

Sliced oat groats are known as steel-cut oats, pinhead oats, coarse or Irish oatmeal.

Coarse barley flour is made by milling barley groats.[4]

Production

[edit]
From the top: fine, medium, and coarsely cut oat groats (i.e. steel-cut oats)
Bottom: uncut oat groats

The grain is cleaned, sorted by the type of grain, its size and then peeled (if necessary) before being hulled. Additionally, the grains can be sliced on a "groat cutter", which can be adjusted to cut fine, medium, or coarse groats. Regardless, thereafter, the groats are freed from any adhering parts of the shell by a brushing machine. In the case of cut groats, their fragments are sorted according to size by sieving.[5]

View on Grokipedia
from Grokipedia
A groat is the hulled kernel of a cereal grain, such as oats, , , or , where only the inedible outer has been removed, leaving the intact , germ, and for a minimally processed form. This processing preserves the grain's full nutritional profile, including high levels of , protein, vitamins, and minerals, while providing a chewy texture and nutty flavor when cooked. The term "groat" derives from "grot," originally meaning a coarse particle, and has been used since for hulled kernels, particularly in Scottish contexts, but now broadly applies to hulled kernels from various cereals, distinguishing them from more refined products like pearled or . Unlike steel-cut or flaked versions, whole groats require longer cooking times—often 30 to 60 minutes—due to their intact structure, making them ideal for hearty porridges, pilafs, soups, or salads. The term is also commonly applied to pseudocereals like . Nutritionally, groats stand out for their role in diets, offering benefits such as improved digestive health from fiber (particularly in s) and lower glycemic impact compared to processed grains, which supports sustained energy and blood sugar management. Varieties like groats, wheat berries (a type of groat), and groats are widely available and versatile, often roasted (as in from buckwheat groats) to enhance flavor before use in both sweet and savory dishes.

Introduction

Definition

A groat is the hulled kernel of various cereal grains, including oats (Avena sativa), wheat (Triticum spp.), barley (Hordeum vulgare), and rye (Secale cereale), or pseudocereals such as buckwheat (Fagopyrum esculentum), consisting of the intact germ, bran, and endosperm. This form represents a whole grain, preserving the nutrient-dense outer layers and inner components of the seed. Unlike unhulled grains, which retain the inedible outer hull, or pearled grains like pearled , which undergo polishing to remove the layer, groats are minimally processed by simply removing the hull, ensuring no loss of the or germ. They also differ from refined flours, which are ground finely after stripping away the and germ, resulting in a loss of and other nutrients. This minimal processing maintains the groat's status as a , with higher nutritional value compared to more refined forms. Groats are typically available as whole kernels or coarsely cracked pieces, offering a chewy texture when cooked due to their intact structure and content.

Etymology and Terminology

The term "groat" originates from Middle English grot or grut, derived from grūt, signifying coarse meal or grit-like particles. This evolved from Proto-West Germanic grot and Proto-Germanic grutą, tied to the concept of or rubbing, ultimately tracing to the Proto-Indo-European ghrew- meaning "to rub" or "," reflecting the coarse, hulled nature of the kernels. By the 13th century, the word had solidified in English usage to describe hulled and minimally processed , emphasizing their unrefined, particle-like form. While "groat" remains the primary English term for hulled kernels of grains such as oats, , , or , linguistic equivalents vary across cultures and languages, often denoting similar coarse preparations. In Russian, kasha typically refers to porridge made from roasted groats, though the word broadly applies to any grain-based . In Hindi and broader South Asian contexts, dalia describes cracked or broken , a form of wheat groats used in porridges and khichdi. Similarly, bulgur in Middle Eastern and Mediterranean traditions names parboiled, dried, and cracked durum groats, prized for their quick cooking and nutty flavor. In modern English, distinctions refine the terminology further: , for instance, are simply oat groats sliced into smaller pieces with steel blades, retaining their whole-grain integrity but reducing cooking time compared to intact groats. "Groats" contrasts with "," the latter in specifically denoting coarsely ground (alkali-treated corn), though both share etymological ties to grytt for coarse meal; this divergence arose as "grits" specialized to corn-based preparations in the , while "groats" stayed general for various hulled grains. Historically, naming shifted from medieval European references to coarse grains in texts like 13th-14th century English culinary manuscripts, where "groats" denoted hulled oats or wheat fragments used in broths and pottages, to contemporary whole-food contexts emphasizing minimally processed, nutrient-dense kernels. This evolution mirrors broader advancements in grain milling, transitioning from manual stone grinding to precise hulling techniques while preserving the term's association with unrefined coarseness.

History and Cultural Significance

Origins and Spread

The origins of groats as a processed product date back to the period in the , where archaeological evidence from sites like Abu Hureyra in reveals the earliest domesticated forms of hulled and around 10,000 BCE. These hulled grains formed the basis of staple foods in early agricultural societies, with similar processing techniques applied to wild and semi-domesticated cereals. By medieval , groats had become a widespread component of diets, valued for their nutritional density, long , and ease of preparation in resource-scarce households. This role is documented in 14th-century English culinary manuscripts, such as , which features recipes like —a made from hulled —highlighting groats' integration into everyday and festive meals across social classes. The spread of groats accelerated through ancient and medieval trade networks, with hulled barley and wheat varieties reaching Central Asia via early trade networks predating the Silk Road, from approximately 3000 BCE to 1500 BCE, where they were adopted into local diets alongside indigenous grains. European colonization in the 16th century further disseminated these cereal grains to the Americas, as Spanish settlers introduced wheat and barley for cultivation in regions like Mexico and the Caribbean, establishing groats as part of colonial food systems. In the 19th and 20th centuries, the industrialization of marked a pivotal shift from traditional home-milling to large-scale commercial operations, with innovations in and milling enabling efficient production and increasing the global availability of groats as a processed staple. This transition, particularly in and , supported broader distribution through factories and improved supply chains, making groats more accessible beyond rural communities.

Regional Variations

In , kasha—a prepared by boiling or millet groats—serves as a foundational staple in Russian and Ukrainian cuisines, reflecting centuries of reliance on hearty, grain-based meals for sustenance. This dish embodies everyday nutrition and cultural identity, as captured in the Russian proverb "Shchi da —pishcha nasha," meaning " and porridge are our food," which highlights its enduring role in traditional diets. kasha, in particular, remains a versatile base for simple boiled preparations, often consumed plain or with minimal additions like or to emphasize the grain's natural flavor and texture. In the , —produced from parboiled, dried, and cracked groats—plays a central role in regional dishes, offering a nutty, chewy staple that enhances and fillings. It forms the base of , a fresh parsley-dominated where fine absorbs lemon juice and , and , a spiced mixture encased in shells, both emblematic of Levantine culinary heritage. In , (also known as harish), a slow-cooked of groats blended with and sometimes sweetened with , represents a comforting dish tied to communal gatherings and festive occasions. South Asian cuisines prominently feature dalia, broken wheat groats that provide a nutrient-dense foundation for both and savory preparations across Indian and Pakistani households. In savory forms like khichdi, dalia is simmered with lentils and spices to create a one-pot meal valued for its digestibility and warmth, commonly served during recovery from illness or as daily fare. For sweets, dalia is transformed into halwa, where the groats are roasted in and sweetened with or sugar, often garnished with nuts, making it a festive treat in regions like and beyond. In , oat groats underpin iconic preparations that blend practicality with tradition, particularly in and . Scottish porridge, crafted from steel-cut or ground oat groats simmered slowly in water or milk, has long been a breakfast ritual promoting endurance in the country's . In 's , groaty pudding—a stew of oat or wheat groats with , leeks, and onions—holds cultural significance as a warming dish traditionally enjoyed on , evoking communal bonfire celebrations since at least the early . North American adoption of oat groats surged in the post-1970s era amid the rising whole-grain movement, which emphasized unprocessed foods for health benefits like improved and heart health. This shift aligned with broader dietary trends promoting natural ingredients, leading to oat groats' integration into health-focused products such as overnight oats and granolas, reflecting a departure from refined cereals toward whole-food simplicity.

Types of Groats

Cereal Grain Groats

Cereal grain groats are the hulled kernels of true cereal grasses from the family, retaining the and germ for maximum nutritional integrity. These minimally processed forms offer a chewy texture and robust flavor, distinguishing them from . groats, derived from Avena sativa, consist of whole kernels with the inedible hull removed, preserving the layer. They are particularly rich in , a soluble concentrated in the that contributes to their health-promoting properties. groats require a cooking time of 45–60 minutes to achieve tenderness. Wheat groats originate from species of Triticum, such as Triticum durum, and encompass whole hulled kernels often processed into cracked forms for culinary use. Notable varieties include , produced by , drying, and cracking the grains, which imparts a nutty flavor suitable for quick-cooking dishes. , another form, involves immature green wheat grains, resulting in a smoky, nutty profile while maintaining the kernel's integrity. These groats are typically used in cracked states to reduce cooking time and enhance digestibility. Barley groats come from Hordeum vulgare and are available as hulled (also known as pot barley) or minimally processed forms, featuring a distinctive chewy texture after cooking. Historically, barley has served as a precursor in beer production through malting, where the groats are germinated to convert starches into fermentable sugars. Rye groats are obtained from Secale cereale, a hardy cereal less commonly processed into groats compared to other grains, and are primarily utilized in Eastern European cuisines for breads and porridges. They exhibit a darker color and stronger, more pungent flavor due to higher levels of phenolic compounds in the bran. Millet groats are sourced from small-seeded grasses in genera such as (e.g., proso millet, Panicum miliaceum) and Pennisetum (e.g., pearl millet, Pennisetum glaucum), which thrive in arid and semi-arid zones of and . These groats appear as tiny, round, bead-like pearls, typically pale yellow or white after hulling, with a mild, slightly sweet taste that absorbs seasonings well. In African contexts, pearl millet groats form the base of thick, fermented porridges like ogi or fura, while in Asia, proso millet varieties feature in lightweight congee-style preparations; both cook rapidly, softening in 15–20 minutes to yield creamy textures ideal for breakfast or staple meals. In general, cereal grain groats boast high content from their intact layer, supporting digestive and . The preservation of this outer layer also confers a longer —up to 8–12 years under proper storage—compared to milled flours, as the whole kernel structure limits rapid oxidation of .

Pseudocereal Groats

Pseudocereal groats refer to the hulled seeds of plants outside the grass family () that are processed and used in ways analogous to cereal grains, providing versatile, gluten-free alternatives in global diets. These seeds, often nutrient-rich, include varieties from , , , which offer distinct textures and flavors suited to porridges, pilafs, and baked goods. Unlike true cereals, pseudocereals derive from dicotyledonous plants, enabling cultivation in diverse environments and contributing to dietary diversity in regions where gluten sensitivity is a concern. Buckwheat groats originate from the seeds of esculentum, a member of the family cultivated primarily in temperate regions. The seeds feature a distinctive triangular shape with three angled faces enclosed by a protective hull that is removed during processing to yield the pale, angular groats. Naturally gluten-free, groats possess an inherent earthy, nutty profile that intensifies when the raw groats are roasted into , a form popular in Eastern European cuisines for its robust flavor in simple boiled dishes. Amaranth groats consist of the minuscule seeds harvested from species in the Amaranthus genus, ancient crops native to Central and now grown worldwide. Measuring about 1–2 mm in diameter, these glossy, bead-sized seeds boast a high protein content relative to many grains, with a subtle, malty flavor when cooked whole. In Latin American traditions, amaranth groats are milled or popped for incorporation into , a warm, maize-based beverage thickened for festive or daily consumption; the seeds also exhibit a unique popping quality when exposed to dry heat, expanding into light, airy puffs reminiscent of miniature . Quinoa groats are produced from the seeds of Chenopodium quinoa, a chenopod originating from the Andean highlands and valued for its adaptability to high-altitude, saline soils. As a seed rather than a true , quinoa requires hulling to strip away the outer pericarp coated in bitter , revealing a tender, ivory-to-red kernel free of residues after processing. This source encompasses all nine essential in balanced proportions, rendering it particularly suitable for plant-based diets when simmered into fluffy grains for salads or sides. What sets pseudocereal groats apart from cereal counterparts is their universal gluten-free status, stemming from non-Poaceae origins, which makes them essential for celiac-safe cooking without compromising texture or nutrition. These groats are generally more nutrient-dense, featuring elevated levels of essential like —often deficient in true —alongside rich profiles that enhance their role as sustainable food staples. Though botanically distinct from grains, their versatility in mimicking or oats underscores their cultural and practical significance across continents.

Production and Processing

Harvesting and Initial Preparation

Harvesting of cereal grains intended for groat production typically occurs when the kernels reach physiological maturity, with moisture content ranging from 14% to 18% to minimize damage while ensuring efficient mechanical separation. For oats specifically, direct harvesting is often initiated at around 13-14% kernel moisture to prevent discoloration and quality loss, though swathing may be used earlier at 30-36% moisture in regions prone to weather delays. Modern practices rely on combine harvesters, which cut the stalks, thresh the grain from the heads, and separate the kernels from chaff and straw in a single pass, reducing labor and post-harvest losses compared to traditional manual methods. Following , the undergoes and sorting to remove impurities such as , stones, dust, and foreign materials, which is essential for preventing spoilage and maintaining for groat . Primary methods include sieving to separate by size, aspiration using controlled airflow to lift lighter and debris, and to extract metallic contaminants or dense stones. These steps are typically performed immediately post- at the farm or initial collection point, achieving purity levels above 99% before further handling. Drying reduces the grain's moisture content to safe storage levels of 12-14%, preventing mold growth and during prolonged storage. Traditional sun-drying involves spreading the on clean surfaces under direct for several days, a method still common in small-scale operations in temperate and tropical regions. In modern , mechanical dryers using heated or ambient air are preferred for efficiency, especially for larger volumes of or , allowing rapid reduction from moisture without quality degradation. Clean, dried grain is then stored in airtight silos or bins to protect against reabsorption and pests, with optimal conditions maintained at 10-15°C and relative humidity below 60% to extend up to 12 months or more. systems in silos help equalize and remove excess , crucial in s where seasonal fluctuations can promote . Yield factors for groat-producing s like oats are heavily influenced by conditions, with average harvests ranging from 2-4 tons per in regions such as and , depending on , rainfall, and variety.

Hulling and Milling Techniques

Cereal grains for groats are categorized as hulled (covered, e.g., oats, ) or hull-less (naked, e.g., , ). For hull-less grains, groats are obtained through and sorting alone, as the kernels separate naturally during without an outer . For hulled grains, hulling mechanically removes the outer to yield intact groats while preserving kernel integrity. This primarily relies on impact dehulling, where grains are accelerated via a rotating disc equipped with fins and propelled against impact surfaces, such as elastomer-lined rings, to and separate the hull without excessive to the . Centrifugal machines facilitate this by generating high-speed impacts, often adjusted for grain size and moisture content—ideally 12-13% for optimal efficiency around 85%. Following hulling, the resulting mixture of groats, hulls, unhulled grains, and fragments undergoes aspiration and sieving for separation, ensuring high-purity output. Milling options then determine the : whole groats may remain intact to retain maximum nutritional value, or they can be cracked into —typically sliced into 1/4-inch pieces using a rotary granulator with a perforated and knives—or finer pinhead oats via additional cutting stages. may be applied optionally to enhance appearance, though it is generally avoided for whole-grain products to maintain integrity. Techniques vary by grain type to accommodate structural differences. Barley, with its tougher hull, requires abrasive dehulling using friction-based mills that scour the outer layers through rubbing against emery or carborundum surfaces. Modern advancements since the mid-20th century have introduced automated processing lines integrating dehullers, cutters, and separators, significantly reducing manual labor and improving throughput. These systems emphasize energy efficiency, with overall milling operations consuming approximately 60-80 kWh per ton, though hulling-specific usage is lower due to mechanical simplicity.

Culinary Uses

Preparation Methods

Groats are typically prepared by soaking them overnight in to soften the grains and reduce subsequent cooking time, often using a 1:3 ratio of grains to ; for instance, soaking oat groats can shorten from approximately 50 minutes to 20-30 minutes. This method also improves digestibility by breaking down some anti-nutrients like . The standard cooking technique involves or groats at 212°F (100°C) in water or , either by absorption—where the liquid is fully taken up—or by draining excess after cooking; groats, for example, are simmered for 10-15 minutes at a to yield a tender yet firm texture. Similarly, hulled groats require 45-60 minutes at a , while groats take about 30-50 minutes at 1:4. preserves more nutrients and results in a fluffier consistency compared to , though it may extend cooking time slightly. Alternative preparation methods include pressure cooking, which significantly shortens the process to 5-10 minutes under high pressure with reduced liquid (about half the stovetop amount), ideal for batch preparation; microwaving suits small portions, typically 10-15 minutes on high with frequent stirring; and dry-roasting groats in a skillet or at 325°F (163°C) for 10-25 minutes before cooking enhances nutty flavors, particularly for . For storage, dry groats remain shelf-stable for 1-2 years in within airtight containers to prevent rancidity from natural oils; cooked groats can be refrigerated for 4-5 days in sealed containers. Texture is controlled by grain form and cooking duration: whole groats yield a chewy bite, while cracked versions soften more quickly; overcooking leads to mushiness, so monitoring absorption and using a 1:2 to 1:4 liquid ratio based on the type helps maintain desired firmness.

Traditional Dishes

Kasha, a staple in Russian and , is a hearty prepared by simmering groats in water or until tender, typically enriched with , mushrooms, or onions for added flavor. It is commonly served as a comforting breakfast or versatile side dish alongside meats or vegetables, reflecting its role as a consumed across all ages. In Middle Eastern cooking, features parboiled and cracked wheat derived from wheat groats sautéed with onions, vegetables such as tomatoes or peppers, and aromatic spices like or , forming a flavorful base for meals. This dish, enjoyed across the region for thousands of years, often incorporates lentils or meat for heartiness and serves as the foundation for salads like , where the bulgur is mixed with fresh herbs, , and . Scottish oatmeal porridge, rooted in the country's agricultural heritage, involves slowly cooking oat groats or steel-cut oats in water or milk over low heat to achieve a creamy consistency, traditionally seasoned simply with salt. Topped with honey, fresh fruit, or cream, it has long been a sustaining breakfast, emblematic of Scotland's reliance on oats as a resilient crop in its climate. Dalia, a versatile Indian preparation using broken (a cracked form of groats), appears in both sweet and savory forms; the sweet version simmers the dalia in milk with , nuts, and to create a pudding-like , while the savory variant combines them with vegetables, lentils, and spices in a nourishing or khichdi. As a major in northern , it is valued for its simplicity and adaptability in daily meals. Groaty pudding, a rustic English dish from the , entails slow-cooking groats with beef, leeks, and stock for hours to yield a rich, stew-like consistency, often enjoyed during autumn festivals as a warming, economical . Harish (also spelled ), known in Yemeni tradition as a porridge of or groats, is boiled with and salt, often including meat such as or lamb, and may be sweetened with or dates for variety. In Scandinavian cuisine, barley groats are used in traditional soups like byggrød, a hearty simmered with or .

Nutritional Profile and Health Benefits

Composition and Nutrients

Groats, as whole, hulled grains, exhibit a nutrient-dense profile characterized by high complex carbohydrates, moderate protein, and significant content. On a dry weight basis per 100 grams, macronutrients typically include 60-75% carbohydrates, primarily in the form of complex starches that provide sustained energy, 10-15% protein of moderate quality, 2-7% total fat (mostly unsaturated), and 5-17% , which includes both soluble forms like in groats and insoluble types across various groats. These values vary by grain type; for instance, groats contain up to 17.3 grams of , while groats provide around 10 grams. Micronutrient content in groats is notably robust, supporting their role as a valuable dietary staple. They are rich in B-vitamins such as thiamin (0.1-0.8 mg/100g) and niacin (1-7 mg/100g), essential for energy metabolism, along with minerals including magnesium (100-230 mg/100g), iron (2-5 mg/100g), and (260-580 mg/100g). Variations occur across types; buckwheat groats, for example, stand out with higher magnesium (231 mg/100g) and (337-577 mg/100g) levels compared to wheat or equivalents. Phytochemicals contribute to the antioxidant potential of groats, with profiles differing by botanical origin. Oat groats contain , unique polyphenols with properties, while wheat groats are rich in , a phenolic compound bound to cell walls that enhances oxidative stability. Cereal groats like those from and include proteins, which provide structural elasticity but are absent in pseudocereal groats such as , making the latter suitable for gluten-sensitive diets; buckwheat notably features high levels of , a . The caloric density of dry groats ranges from 330 to 390 kcal per 100 grams, reflecting their dominance, with processed forms maintaining less than 10% to ensure stability and nutrient preservation. Compared to , whole groats retain substantially more nutrients; for example, they offer approximately three times the of white flour equivalents, along with higher levels of vitamins, minerals, and phytochemicals lost during milling.

The U.S. has approved a stating that consuming at least 3 grams of per day from or , as part of a diet low in and , may reduce the risk of coronary heart disease. Meta-analyses of randomized controlled trials confirm that intake leads to a 5-10% reduction in , with greater effects observed in individuals with elevated baseline levels. The high fiber content in groats, including both soluble and insoluble forms, supports digestive health by promoting regularity and preventing . Insoluble adds bulk to stool and facilitates its movement through the intestines, while soluble like absorbs water to soften stool. Additionally, in and groats acts as a prebiotic, fermenting in the colon to produce that nourish beneficial gut and enhance overall gut . Groats exhibit a low glycemic index (GI), typically ranging from 31 to 55 depending on the type, which contributes to better blood sugar control by slowing glucose absorption from whole kernels. This property is particularly beneficial for , as evidenced by studies showing that groats improve insulin sensitivity and reduce postprandial blood glucose excursions in individuals with . Barley and groats similarly attenuate glycemic responses compared to , supporting stable energy levels and reduced insulin demand. Oat groats contain , unique polyphenols with potent and properties that mitigate by scavenging free radicals and inhibiting pro-inflammatory pathways. Research from the 2020s has further linked oat consumption, including groats, to favorable shifts in the , such as increased abundance of beneficial bacteria like Akkermansia muciniphila and Roseburia, which produce short-chain fatty acids. These effects collectively reduce and support immune modulation. The combination of and protein in groats promotes , aiding by reducing overall calorie intake and curbing hunger. Prospective cohort studies, including the , have associated higher consumption—like that from groats—with lower (BMI) and reduced risk of over time, attributing these outcomes to enhanced feelings of fullness and improved metabolic regulation. Pseudocereal groats, such as those from , , and , play a vital role in gluten-free diets for individuals with celiac disease, providing nutrient-dense alternatives that prevent nutritional deficiencies common in gluten avoidance. Post-2024 research highlights their superior , bioavailability, and content, which enhance adherence to gluten-free regimens while supporting gut healing and reducing inflammation in celiac patients.
