Abstract

The invention discloses a method for obtaining high-purity squalene from a vegetable oil deodorized distillate. The method comprises the following steps: first performing esterification / ester exchange, crystallization and molecular distillation on the vegetable oil deodorized distillate (DD oil) to obtain a vitamin E and squalene mixture; performing vitamin E adsorption on the mixture through strong basic anion resin; performing sampling and impurity washing on the resin with a low alcohol solution to obtain impurity-washed oil and effluent; concentrating the impurity-washed oil and the effluent; then performing saponification, crystallization, and filtration to obtain squalene-rich filtrate; then performing two-stage molecular distillation on the filtrate so as to obtain the high-purity squalene. According to the method disclosed by the invention, the high-purity squalene is obtained from the DD oil on a large scale by adopting an industrially feasible way; the problems of insufficient raw materials and ever-increasing market demand of the squalene at present can be effectively solved; meanwhile, vitamin E, fatty acid methyl ester, sterol are also obtained, and DD oil resources are fully utilized.

Description

technical field [0001] The invention belongs to the technical field of recovery and utilization of vegetable oil deodorization distillates, and in particular relates to a method for obtaining squalene from vegetable oil deodorization distillates. Background technique [0002] Squalene is a class of highly unsaturated straight-chain triterpenoids with the molecular formula C 30 h 50 , is a colorless or yellowish transparent oily liquid. Squalene has various biological activities such as anti-oxidation, anti-tumor, anti-infection, and promotion of cardiovascular and cerebrovascular health, and is widely used in the fields of pharmaceuticals, cosmetics, and health products. At present, the main source of squalene is shark oil, which is expensive, so there is an urgent need for suitable raw material replacements to meet the large market demand. Synthesizing squalene by chemical means is an effective solution. However, due to the particularity of its structure, the reaction p...
