Sesame oil
Sesame oil is an edible vegetable oil derived from sesame seeds. The oil is one of the earliest-known crop-based oils. Worldwide mass modern production is limited due to the inefficient manual harvesting process required to extract the oil. Oil made from raw seeds, which may or may not be cold-pressed, is used as a cooking oil. Oil made from toasted seeds is used for its distinctive nutty aroma and taste, although it may be unsuitable for frying, which makes it taste burnt and bitter.
Sesame seeds are protected by a capsule which bursts only when the seeds are completely ripe, a process called dehiscence. The dehiscence time tends to vary, so farmers cut plants by hand and place them together in an upright position to continue ripening, until all the capsules have opened.
Tanzania remains the largest producer of sesame oil and also dominates the global consumption of this product. The African and Asian regions constitute the fastest-developing sesame oil markets. The steady growth in demand being observed here is in line with rising household income and urbanization, as well as an increase in the use of sesame oil for food products and Asian dishes.
While some manufacturers will further refine sesame oil through solvent extraction, neutralization, and bleaching in order to improve its cosmetic aspects, sesame oil derived from quality seeds already possesses a pleasant taste and does not require further purification before it can be consumed. Many consumers prefer unrefined sesame oil due to their belief that the refining process removes important nutrients. Flavor, traditionally an important attribute, was best in oils produced from mild crushing.
Sesame oil is one of the more stable natural oils, but can still benefit from refrigeration and from limited exposure to light and high temperatures during extraction, processing, and storage; this minimizes nutrient loss through oxidation and rancidity. Storage in amber-colored or opaque bottles can help to minimize light exposure.
Sesame oil is a polyunsaturated (PUFA) semi-drying oil. Commercial sesame oil varies in color from light to deep reddish-yellow depending on the color of the seed processed and the method of milling. Provided that the oil is milled from well-cleaned seed, it can be refined and bleached easily to yield a light-colored limpid oil. Sesame oil is rich in oleic and linoleic acids, which together account for 85% of the total fatty acids. Sesame oil has a relatively high percentage of unsaponifiable matter (1.5-2.3%). In India and in some other European countries, it is obligatory to add sesame oil (5-10%) to margarine and generally to hydrogenated vegetable fats which are commonly used as adulterants for butter or ghee.[citation needed]
About 65% of the annual US sesame crop is processed into oil, and 35% is used in food.
A 100 gram (100 ml) reference amount of sesame oil supplies 884 calories of food energy (table). The only essential nutrient having significant content in sesame oil is vitamin K, providing 13% of the Daily Value per 100 grams (table).
