Embodiment 1

[0019] In the embodiment of the present invention, a method for extracting natural tocopherol, the specific steps include:

[0020] 1) The DD oil in the raw material tank, the methanol in the methanol head tank, and the sulfuric acid in the sulfuric acid head tank were added to the esterification kettle with stirring, and the amount of methanol added was 28% of the mass of rubber oil, and the addition of sulfuric acid The amount is 2% of the sizing oil quality, and the esterification reaction is carried out under the condition of heating and reflux, and the reaction is 3h to obtain the mother liquor;

[0021] 2) Transfer the mother liquor in step 1) to the cold analysis tank, wash with water at 3°C, and cold precipitate solid crystals, and then use a solid-liquid separator to separate the solids as by-products to obtain crude sterols, which are decolorized and alcohol crystallized. Produce refined sterols;

[0022] 3) The mother liquor separated in step 2) is washed with wate...

Embodiment 2

[0026] In the embodiment of the present invention, a method for extracting natural tocopherol, the specific steps include:

[0027] 1) The DD oil in the raw material tank, the methanol in the methanol head tank, and the sulfuric acid in the sulfuric acid head tank were added to the esterification kettle with stirring, and the amount of methanol added was 30% of the mass of rubber oil, and the addition of sulfuric acid The amount is 3% of the sizing oil quality, and the esterification reaction is carried out under the condition of heating and reflux, and the reaction is carried out for 4 hours to obtain the mother liquor;

[0028] 2) Transfer the mother liquor in step 1) to the cold analysis tank, wash with water at 5°C, and cold precipitate solid crystals, and then separate the solids as by-products with a solid-liquid separator to obtain crude sterols, which are decolorized and alcohol crystallized. Produce refined sterols;

Abstract

The invention discloses a natural tocopherol extract method including the following steps: 1) respectively adding DD oil, methanol and sulfuric acid into an esterification kettle to carry out an esterification reaction to prepare a mother liquid; 2) feeding the mother liquid to a cold-crystallization kettle, water-washing and cold-crystallizing the mother liquid to obtain a solid crystal, and performing separation through a solid-liquid separator to obtain a sterol crude product; 3) performing secondary water washing to the separated mother liquid and separating water through an oil-water separator; 4) pre-treating the mother liquid through dehydrating and degasifying apparatuses, feeding the mother liquid into a short-path distillalion system to firstly distill fatty acid methyl ester and then distill a vitamin E crude product; and 5) performing a derivatization reaction, extraction and desolventizing separation to the vitamin E crude product to obtain a finish product. In the invention, the natural vitamin E is prepared through esterification to the mother liquid with acetate by means of the derivative extraction process, wherein the natural vitamin E can improve body functions. The product is high in quality and is stable in processes. The method is simple in production line, saves cost, is free of pollution and is safe and environment-friendly.

Description

technical field [0001] The invention relates to extraction technology, in particular to an extraction method of natural tocopherol. Background technique [0002] With the rapid development of science and technology in the food industry and the improvement of people's living and consumption levels, the concept of diet has undergone tremendous changes, and nutrition and function have become the focus of attention. As one of the three major nutrients, fat has received widespread attention in terms of its effect on health. At present, my country's popular edible oil is very close to developed countries in terms of scale and grade. There is not much room for development in the development of conventional oils. It is necessary to turn to the development and research of oil by-products and functional ingredients. Functional fatty acids refer specifically to those derived from human dietary oils and fats, which are necessary for human nutrition and health, and can be used for some ...
