Problems solved by technology

The pressing method has become the main method developed in recent years due to its advantages of high degree of self-control and continuous production. However, the sesame oil produced by the traditional pressing method has poor color, poor transparency, large loss of nutrients and active substances, and serious sesame protein. Deformation and damage, resulting in sesame cakes and slag can only be used as cheap feed, resulting in a waste of sesame protein resources

Abstract

The invention discloses a processing method of sesame oil. The processing method comprises the following steps: adding sesame into an aqueous solution of sodium hydroxide for soaking, washing, peeling, drying and carrying out microwave processing to obtain pretreated sesame; adding the pretreated sesame into a hydraulic oil press, and carrying out first-time squeezing to obtain first-time squeezedsesame oil and squeezed sesame-seed cakes; adding the sesame-seed cakes into the hydraulic oil press, and carrying out second-time squeezing to obtain second-time squeezed sesame oil; mixing the first-time squeezed sesame oil with the second-time squeezed sesame oil to obtain crude oil; carrying out air drying on radix glycyrrhizae, fructus momordicae, cortex eucommiae and garlic stems and leaves, crushing, and carrying out microwave processing and CO2 supercritical extraction in sequence to obtain a plant extract; adding the plant extract, resveratrol and organic acid into the crude oil, decoloring, standing and filtering to obtain discolored sesame oil; cooling the discolored sesame oil and then adding diatomite, standing and filtering. The processing method of the sesame oil, providedby the invention, is simple in process and high in oil yield, facilitates industrialization, and retains protein in the sesame-seed cakes; the obtained sesame oil has the advantages of light color, high transparency and good quality.

Description

technical field [0001] The invention relates to the technical field of sesame oil, in particular to a processing method of sesame oil. Background technique [0002] Sesame is not only rich in oil and protein, but also has good health care and medicinal value. In recent years, the consumption of sesame and sesame processed products in China has been increasing year by year. Sesame oil has a special fragrance and has been a high-grade edible oil loved by people since ancient times. At present, the production techniques of sesame oil include water substitution method and pressing method. The pressing method has become the main method developed in recent years due to its high degree of self-control and continuous production. However, the sesame oil produced by the traditional pressing method has poor color, poor transparency, large loss of nutrients and active substances, and serious sesame protein. Deformation and damage cause sesame cakes and slag to be used as cheap feed, ...
