Riceberry
View on Wikipedia

Riceberry (Thai: ข้าวไรซ์เบอร์รี่) is a rice variety from Thailand, a cross-breed of kao-jao hom nin (a local non-glutinous purple rice) and (hom mali rice).[citation needed] The variety was created in 2002 by the Rice Science Center, Kasetsart University, Kamphaeng Saen Campus, Nakhon Pathom, Thailand.[1] The outcome is a soft, deep purple whole grain rice.
Riceberry is grown primarily in northern and northeastern Thailand.[citation needed] The wet season months of August through December are suitable for riceberry planting.

Nutrition
[edit]Riceberry contains anthocyanins and carotenoids, and has a glycemic index of 62.[citation needed]
Governmental support
[edit]The Commerce Ministry aims to increase riceberry cultivation from 5,000 rai to 20,000 rai (3,200 hectares) by 2018 to address in the world market demand for organic brown rice. The yield from 5,000 rai amounts to only 1,500 tonnes.[3] Demand for premium organic rice is still small, accounting for only one to two percent of total rice exports, but as riceberry sells for two or three times the price of white rice,[4] it has the potential to increase farming incomes.[5] As of 2015[update] Riceberry sold in the domestic market for about 50 baht a kilogram, while the export price was 200 baht per kilogram.[3]

Origin and Breeding
Riceberry, a hybrid rice variety, was developed in 2002 at the Rice Science Center of Kasetsart University in Thailand through conventional cross-breeding techniques.[3] The breeding program aimed to merge the fragrant aroma and soft texture of Thai Hom Mali rice (Oryza sativa cv. Khao Dawk Mali 105) with the high anthocyanin content and nutritional richness of the indigenous purple rice variety Jao Hom Nin, without employing genetic modification.[3] This traditional pollination method involved selecting parent lines for their complementary traits: the aromatic qualities from the jasmine-type Hom Mali and the antioxidant-dense pigmentation from the non-glutinous purple Jao Hom Nin.[3] The project was led by Professor Apichart Vanavichit and his research team at the Rice Science Center, focusing on creating a whole-grain rice that enhances dietary health while maintaining palatability.[3] Over the subsequent years, the hybrid underwent extensive evaluation to stabilize desirable characteristics, including nutritional enhancement and agronomic performance.[3] It was released in 2005 by Kasetsart University, Mahidol University, and Chiang Mai University, with trademark registration in 2012 and endorsement under the plant variety protection law in 2017.[4][5][2] These efforts resulted in Riceberry's unique profile, blending sensory appeal with elevated bioactive compounds derived from its pigmented parentage.[3]Market Introduction
Riceberry was released in 2005 by public universities and entered the Thai market around 2010, building on breeding success that enabled its market viability.[2][4] Initial promotion positioned Riceberry as a "superfood" rice, emphasizing its rich antioxidant profile and health benefits to appeal to health-conscious urban consumers in Thailand.[6] Market expansion accelerated in the mid-2010s, with exports commencing to key regions including Asia, Europe, and North America, driven by growing global demand for nutrient-dense grains. By 2020, annual production had scaled to thousands of tons, cultivated across approximately 20,000 rai (about 3,200 hectares) primarily in northern and northeastern Thailand, supported by organic certifications such as USDA and EU standards.[3]Physical Characteristics
Grain Appearance and Texture
Riceberry grains exhibit a distinctive deep purple to black coloration in their raw form, primarily due to anthocyanin pigments concentrated in the pericarp and bran layers.[7] The hull appears deep purple-black, providing a striking visual contrast to typical white or brown rice varieties.[8] When cooked, the grains develop a rich, dark purple hue that enhances their aesthetic appeal.[8] In terms of shape and size, Riceberry grains are long and slender, resembling those of jasmine rice, with an unpolished grain length of approximately 6.9 mm and a width of about 2.0 mm, yielding a length-to-width ratio exceeding 3.0.[9] This slender profile contributes to their elegant appearance and uniform cooking behavior. The milling process for Riceberry involves removing only the outer husk, while retaining the bran layer to preserve its whole-grain status and characteristic pigmentation.[10] This minimal processing maintains the grain's integrity, avoiding the polishing that removes the bran in white rice varieties. Cooked Riceberry grains possess a soft and chewy texture with a slightly sticky consistency, offering a pleasant mouthfeel that is more tender than typical brown rice.[11] The retained bran layer imparts a subtle nutty quality, distinguishing it from smoother, less fibrous grains.[8]Aroma and Cooking Properties
Riceberry rice exhibits a distinctive aroma profile characterized by nutty and floral notes reminiscent of jasmine rice, complemented by subtle berry-like undertones arising from the presence of p-hydroxyphenylbutan-2-one (raspberry ketone).[12] This fragrance emerges prominently during cooking and persists post-preparation, contributing to its sensory appeal without diminishing under heat or processing. The stability of these aromatic compounds, even after ultrapasteurization, distinguishes Riceberry from other pigmented rices.[13] In terms of cooking properties, Riceberry rice cooks in approximately 25-35 minutes using conventional methods such as an electric cooker or stovetop, akin to many whole-grain varieties though faster than typical brown rice due to its hybrid breeding. It absorbs 1.5 to 2.2 times its volume in water, depending on the desired consistency and method, with optimal ratios around 1:1.8 for balanced hydration. Upon cooking, the grains expand to roughly double their original size, yielding a fluffy, soft texture with slight stickiness that maintains structural integrity, ideal for versatile applications. For storage, Riceberry rice maintains viability for 1-2 years in cool, dry, airtight conditions as a whole-grain product, similar to other brown rices, owing to the inherent stability of its aromatic compounds. However, to preserve peak aroma and flavor intensity, consumption within 6 months of harvest is recommended, as oils in the bran layer can gradually oxidize over longer periods.Nutritional Profile
Macronutrients and Micronutrients
Riceberry rice, on a dry weight basis, consists primarily of carbohydrates at approximately 80 g per 100 g, making it a high-energy staple similar to other whole grain varieties. Protein content ranges from 7 to 8 g per 100 g, providing essential amino acids, while fat is present at 3 to 4 g per 100 g, predominantly unsaturated fatty acids from the bran layer. Dietary fiber accounts for about 4 g per 100 g, contributing to its whole grain status. These macronutrient proportions yield a caloric value of approximately 370 kcal per 100 g, positioning Riceberry as a nutrient-dense carbohydrate source according to analyses from the Rice Science Center at Kasetsart University. Values may vary by cultivation conditions and region.[14][1] In terms of micronutrients, Riceberry rice is enriched compared to polished white rice, particularly in minerals vital for metabolic functions. Iron levels are approximately 1.5 to 4 mg per 100 g (varying by soil conditions, up to 2-3 times the content found in conventional white rice varieties such as Hom Mali). Zinc is present at around 3 mg per 100 g, supporting enzymatic processes and immune health. Folic acid content is approximately 48 mcg per 100 g, aiding in cellular division. These values are derived from laboratory tests conducted under Thai agricultural standards between 2020 and 2023, highlighting Riceberry's retention of bran-derived nutrients. Values may vary by cultivation conditions and region.[15][16][1][17][18] The estimated glycemic index (eGI) of Riceberry rice is low at approximately 62-63, lower than many white rice types (eGI ~73), due to its fiber and complex carbohydrate structure. This metric, measured via in vitro starch hydrolysis assays, underscores its suitability as a stable energy source without rapid blood sugar spikes.[19]| Nutrient | Amount per 100 g (dry weight) | Comparison to White Rice |
