Byproducts of Sesame Oil Extraction: Composition, Function, and Comprehensive Utilization

Area of Science:

• Agricultural Science
• Food Science
• Biochemistry

Background:

• Sesame meal is a primary byproduct of sesame oil extraction, often discarded.
• This byproduct is rich in valuable compounds: sesame protein and three key lignans (sesamin, sesamolin, and sesamol).
• Current disposal practices lead to resource waste and economic losses.

Purpose of the Study:

• To review extraction methods for active compounds in sesame meal.
• To summarize the functional activities of these extracted compounds.
• To provide guidance for the comprehensive utilization of sesame meal to maximize its value.

Main Methods:

• Literature review of extraction techniques for sesame protein and lignans.
• Analysis of documented biological activities and applications of extracted compounds.
• Synthesis of information on the comprehensive utilization of sesame meal components.

Main Results:

• Sesame protein, extracted physically or enzymatically, offers balanced amino acids for feed and supplements.
• Extracted sesame lignans possess beneficial biological activities, including antihypertensive, anticancer, and cholesterol-lowering properties.
• These lignans enhance the oxidative stability of oils.

Conclusions:

• Sesame meal is a valuable source of bioactive compounds.
• Effective extraction and utilization of sesame protein and lignans can mitigate waste and create economic opportunities.
• This review provides a foundation for maximizing the comprehensive utilization of sesame meal.
