Abstract

The invention discloses a method for preparing sesame oil by enzymolysis and supercritical fluid extraction. The method comprises the following steps: (1) preparing sesame pulp, namely smashing sesame into fine powder of 100-300 meshes, adding water in 5-7 times by weight of the sesame, uniformly stirring, heating to 40-50 DEG C, and performing heat preservation for 15-20 minutes, so that the sesame pulp is obtained; (2) carrying out enzymolysis, namely regulating pH of the obtained sesame pulp to 4.0-5.0, adding compound enzyme accounting for 0.2-0.3% of the weight of the sesame pulp and carrying out enzymolysis; and (3) carrying out supercritical fluid extraction, namely placing the sesame pulp subjected to enzymolysis in step (2) into an extraction kettle, and carrying out supercritical extraction by taking supercritical CO2 fluid as an extraction solvent and an ethanol solution with volume concentration of 60-70% as an entrainer, so that the sesame oil is obtained. Compared with the prior art, the method for preparing the sesame oil by enzymolysis and supercritical fluid extraction has the advantages that oil yield is high, technology is simple, production efficiency is high and safety and reliability are realized.

Description

technical field [0001] The invention relates to the technical field of vegetable oil preparation, in particular to a method for enzymatic hydrolysis and supercritical extraction of sesame oil. Background technique [0002] Sesame oil, also known as sesame oil, is extracted from sesame seeds and has a special fragrance, so it is called sesame oil. Sesame belongs to the genus of Flaxaceae, and is one of the four major oil plants in my country. There are two kinds of black and white. White sesame is better for food, and black sesame is better for medicine. The stems, leaves, pods and flowers of sesame can be used as medicine. Sesame contains vitamin E, vitamin B1, linoleic acid, protein, sesame sugar, pentosan, calcium, phosphorus, iron and other minerals and various rich nutrients. Among them, vitamin E, which has the most content and becomes the main component, is often called the anti-aging vitamin. It has a good effect on improving blood circulation and promoting metaboli...
