Method for extracting various active components from deodorized distillate

Abstract

The invention provides a method for extracting various active components from deodorized distillate, wherein the method comprises the following steps: S1, adding methanol and lipase into the deodorized distillate, and performing esterification reaction; S2, performing cold separation on the esterification product, and filtering to obtain sterol; S3, performing three-stage molecular distillation on the filtrate obtained in the step S2 to distill out a vitamin E primary extract with the content of 10-27 wt%; and S4, performing five-stage high-vacuum rectification by taking the vitamin E primary extract distilled in the step S3 as a raw material to respectively rectify squalene, soybean vitamin E and alpha vitamin E. According to the method, various active ingredients are extracted through one process, the operation is simple, and the cost is low.

Description

Technical field [0001] The present invention relates to a method of extracting a plurality of active ingredients from a deodorant fraction, belonging to the technical field of deodorization distillate treatment. Background technique [0002] Deodorant distillate is a vegetable oil in the production and refining process of corn oil, rapeseed oil, peanut oil, sunflower seed oil, palm oil and other food oil. The deodorant distillate contains a lot of useful ingredients. For example, squalene, sterol, vitamin E (Ve), etc. Among them, the VE content is 2 to 8 wt% (wherein αVE accounts for 20 ~ 35 wt%); the sterol content is 2 to 8% by weight; the acid price is 100 to 140 mgkOH / g. [0003] These a variety of active ingredients are extracted from deodorant distillate. However, since the composition of the deodorization distillate is complex, the various active ingredients need to be purified by different processes, respectively, and the operation is complex, and the cost is high.

AI Technical Summary

Problems solved by technology

However, due to the complex composition of the deodorized distillate, various active components need to be purified separately through different processes, the operation is complicated and the cost is high

Moreover, the traditional extraction method of VE is difficult to purify to more than 50%

In addition, the natural high-purity αVE on the market cannot be directly extracted from the raw materials. It is all extracted from mixed vitamin E first, and then the other three VE (βVE, γVE, δVE) are converted into αVE through methylation and hydrogenation treatment. Complicated operation and high cost
