Embodiment 1

[0027] After crushing the sesame seeds, soak them in an extraction tank with a concentration of more than 99% ethyl acetate for 40 minutes at a soaking temperature of 75°C, wherein the weight ratio of the sesame seeds to the extractant ethyl acetate is 1:4.6.

[0028] In the extraction tank, keep the extraction temperature at 80°C, and extract the sesamin for 1.5 hours to obtain an extract containing sesamin;

[0029] Use a three-effect concentrator to concentrate the extract, and the temperature in the concentrator is 75°C; obtain a concentrated solution containing sesamin; add the concentrated solution to a crystallization tank and keep stirring for 16 hours, and then crystallize to obtain sesamin crystals, The crystallization temperature is 3 DEG C; the sesamin crystals are added into a refining tank, and ethanol is added for decolorization and refining to obtain the finished sesamin.

[0030] In the present embodiment, the amount of sesame seasoning is 150kg; the final pro...

Embodiment 2

[0032] After the sesame is crushed, it is soaked in an extraction tank of ethanol with a concentration of more than 99% for 60 minutes at a soaking temperature of 80°C, and the weight ratio of the sesame to the extractant ethanol is 1:5.

[0033] In the extraction tank, keep the extraction temperature at 80°C, and extract the sesamin for 1 hour to obtain an extract containing sesamin;

[0034] Use a three-effect concentrator to concentrate the extract, and the temperature in the concentrator is 65°C; obtain a concentrated solution containing sesamin; add the concentrated solution to a crystallization tank and keep stirring for 16 hours, and then crystallize to obtain sesamin crystals, The crystallization temperature is 2° C.; the sesamin crystals are added into a refining tank, and ethanol is added for decolorization and refining to obtain a finished sesamin product.

[0035] In the present embodiment, the amount of sesame seasoning is 150kg; the final product solid sesamin ob...

Abstract

The present application relates to a method for extracting sesamin, which is characterized in that it comprises: soaking crushed sesame in an extraction tank containing an extractant for a predetermined time; extracting sesame in the extraction tank to obtain an extract containing sesamin liquid; use a three-effect concentrator to concentrate the extract to obtain a concentrated solution containing sesamin; add the concentrated solution to a crystallization tank for crystallization to obtain sesamin crystals; add the sesamin crystals to a refining tank and add ethanol for Decolorizing and refining to obtain the finished product of sesamin. Using the extraction method of the scheme of the present application improves the purity of sesamin, reduces production energy consumption and production cost.

Description

technical field [0001] The invention relates to a method for continuously extracting sesamin from sesame, in particular to an ultrahigh-purity sesamin extraction method. Background technique [0002] Sesamin (English name: sesamin), is a white crystalline powder, easily soluble in chloroform, benzene, acetic acid, acetone, slightly soluble in ether, petroleum ether. Almost insoluble in water, alkaline solution and hydrochloric acid, sesamin mainly exists in sesame, asarum in Aristolochiaceae Asarum, Rutaceae Zanthoxylum chinensis, Bashan Zanthoxylum bungeanum, Zizhuye and other Chinese herbal medicines It has also been found to contain sesamin. Compared with the mass content of sesamin in sesame, the mass content of sesamin in other plants is very low. Since sesamin is fat-soluble, most of the sesamin is distributed in sesame oil. Sesamin content in sesame oil is between 0.06% -0.74%. [0003] The molecular structural formula is as follows: [0004] [0005] Sesamin ...
