Sesame is a flowering annual that is widely naturalized and cultivated in tropical regions throughout Asia and the Middle East. It is one of the oldest oilseed crops, with domestication dating to about 3,000 years ago in China.
The dried seed is a rich source of fatty acids, including oleic acid and linoleic acid, as well as iron, magnesium, phosphorus and zinc. Black sesame seeds are the same as white sesame seeds except that the hull is left intact.
