Problems solved by technology

[0005] At present, the methods for extracting sesamin from sesame cake include solvent extraction, solvent-recrystallization, solvent-chromatography and other extraction methods, but the problems in these methods are: the extraction rate of sesamin is low, and the sesamin in sesame cake It contains more oil and protein, which also brings great difficulties to the extraction of sesamin. Moreover, due to the chemical pollution in the solvent, the product has disadvantages such as low quality and chemical residues.

Embodiment Construction

[0024] The present invention will be further described below in conjunction with specific examples.

[0025] Using 100 tons of sesame cake as raw material:

[0026] First degrease the sesame cake: the sesame cake is first dried at 65°C, crushed into 40 mesh, and then degreased with 3 times the volume of ethanol and ethyl acetate, degreased twice, and solidified by centrifugal filtration at 3000r / min. The liquid is separated, the residual oil in the sesame cake is removed, dried and pulverized to obtain the degreased sesame meal powder.

[0027] Then extract protein from the degreased sesame meal powder: first hydrolyze with trypsin, treat at 50°C and pH7.5 for 3 hours, use 0.05% plum enzyme, and then carry out lye extraction, the condition is pH13, liquid-to-material ratio is 12: 1. The temperature is 80°C, the time is 2H, and the solid-liquid separation is carried out by centrifugation at 3000r / min. The solid phase is dried and crushed to obtain deproteinized sesame meal, an...

Abstract

The invention discloses a method for extracting sesamin from sesame cake meal, wherein the sesamin is extracted from the raw material of waste sesame cake meal of sesame oil plants. The method comprises the steps of: removing residual oil by utilizing ethanol and ethyl acetate, hydrolyzing protein by utilizing protease, extracting the protein in the hydrolysate by utilizing alkali liquor, and subjecting the oil and protein removed sesame cake meal to supercritical CO2 extraction to obtain the sesamin. The method for extracting the sesamin from the sesame cake meal has the advantages that: physiological active materials such as the sesamin and the like with high additional value are extracted from the waste cake meal left after the sesame oil is extracted from the sesame, therefore, the environmental pollution caused by the waste sesame residue can be reduced and the good economic benefit can be produced so as to drive the further processing study of our country on the sesame, push forward the planting of a characteristic oil crop which is the sesame of our country, promote the structure adjustment of agriculture and increase the income of peasant.

Description

Technical field: [0001] The invention relates to a method for extracting sesamin, in particular to a method for extracting sesamin from sesame cake. Background technique: [0002] Sesamin, also known as sesamin, sesamin, or sesame, is a natural component in sesame seeds, and its content is about 0.5%. The melting point and solubility of sesamin are 122°C-123°C. Sesamin can be freely dissolved in chloroform, ethanol and acetone. Pharmacological effects According to animal and human experiments, sesamin has the functions of anti-hypertension and cardiovascular hypertrophy, liver protection, anti-oxidation, lowering cholesterol, inhibiting skin cancer, and protecting the liver. [0003] Due to its unique physical and chemical properties and physiological functions, sesamin has great application prospects in agriculture, food industry and pharmaceutical industry. High-purity sesamin is gradually used in security and medicine. The price of high-purity sesamin is very expensive ...
