Abstract
Sesame seed (Sesamum indicum L.) is one of the world's most important and oldest oilseed crops with a high level content of nutrients and antioxidants known to human health. Sesame seeds are usually roasted prior to expelling oil. The changes of chemical composition, functional properties and antioxidant activity of defatted sesame seeds meal (DSSM) before and after roasting were investigated. The DSSM samples contained 1.72-2.76% moisture, 2.20-3.58% crude oil, 45.05-55.20% crude proteins, 9.60-20.51% carbohydrate (by difference), 22.49-24.48% crude fiber and 5.11-6.94% ash. A significant reduction was observed in the mineral composition with roasting treatment when compared with the raw sample. Functional properties (WAC and OAC) of DSSM were also determined. The antioxidant factors responsible for the stability of DSSM are highly affected by the roasting process. The total phenolics content in the methanolic extract from DSSM and the antioxidant activity of DSSM also increased with roasting.
