Problems solved by technology

[0004] The capsanthin prepared by the prior art contains a large amount of orange and yellow pigments such as β-carotene and zeaxanthin, which reduces the light absorption ratio of the capsanthin, and the lower the light absorption ratio of the capsanthin shows that the color of the capsanthin tends to be higher. close to orange

preparation example Construction

[0024] The invention provides a preparation method of capsanthin, comprising:

[0025] a) mixing the capsicum powder and the extractant in a continuous extractor to obtain a pigment extract;

[0026] b) vacuum-concentrating the pigment leachate to obtain a concentrated pigment solution;

[0027] c) performing chromatographic separation on the concentrated pigment solution to obtain capsanthin after removing the spicy taste.

[0028] According to the present invention, firstly, the pepper is dried at 30° C. to 50° C. to remove moisture in the pepper; then the dried pepper is pulverized to obtain pepper powder. In the present invention, the capsicum peel of the red pepper is preferably used as the main raw material to prepare the powder. In addition, the capsanthin can be extracted after the capsicum powder is granulated. The pepper powder is conveyed into the interior of the continuous extractor through the auger on the upper part of the continuous extractor. During the conve...

Embodiment 1

[0035] Take 2000kg of Xinjiang red pepper skin, pulverize and granulate, extract with a flat rotary continuous extractor to obtain a pigment extract, then vacuum concentrate the extract to obtain 120kg of pigment concentrate, and the vacuum concentration pressure is -0.03MPa. Mix 500kg of 70% ethanol with the pigment concentrate to remove the spicy taste, and obtain 78kg of the pigment concentrate that removes the spicy taste. Put the concentrated solution of the pigment that has removed the spicy taste on the upper part of the silica gel column, and carry out the separation operation of the silica gel column chromatography. Firstly, the silica gel column was rinsed with 4000 L of petroleum ether at a flow rate of 0.3 column volume / h to obtain petroleum ether eluent. Then use 4000 L of acetone to rinse the silica gel column at a flow rate of 0.3 column volume / h to obtain an acetone eluent. The acetone eluate was concentrated in vacuo to obtain 71 kg of capsanthin.

Embodiment 2

[0038]Take 2000kg of Shandong red pepper skin, crush and granulate, extract with a flat rotary continuous extractor to obtain a pigment extract, then vacuum concentrate the extract to obtain 108kg of pigment concentrate, and the vacuum concentration pressure is -0.03MPa. Mix 450kg of 70% ethanol with the pigment concentrate to remove the spicy taste, and obtain 60kg of the pigment concentrate that removes the spicy taste. Put the concentrated solution of the pigment that has removed the spicy taste on the upper part of the silica gel column, and carry out the separation operation of the silica gel column chromatography. The silica gel column was first rinsed with 4500 L of petroleum ether at a flow rate of 0.3 column volume / h to obtain a petroleum ether eluent. Then, 2500 L of acetone was used to rinse the silica gel column at a flow rate of 0.3 column volume / h to obtain an acetone eluent. The acetone eluate was concentrated in vacuo to obtain 53 kg of capsanthin.

Abstract

The invention provides a preparation method of capsanthin, which comprises the following steps of: a) mixing chili powder and a leaching agent in a continuous extractor to obtain a pigment extract; b) performing vacuum concentration on the pigment extract to obtain pigment concentrated solution; and c) removing the sharp taste of the pigment concentrated solution and then performing chromatographic separation to obtain the capsanthin. The preparation method of the capsanthin uses the continuous extractor to ensure that the capsanthin is extracted more sufficiently and the extraction process can be operated continuously, so the preparation method is suitable for industrial preparation of the capsanthin. Besides, the preparation method of the capsanthin also uses a chromatographic separation technique to separate orange and yellow pigments such as beta-carotene, zeaxanthin and the like out from the capsanthin so as to improve the concentration of red pigments in the capsanthin and improve the absorbance ratio of the capsanthin.

Description

technical field [0001] The invention relates to the field of food additives, in particular to a preparation method of capsanthin. Background technique [0002] Capsanthin is a composition composed of a variety of natural pigments, and its ingredients are capsanthin, capsorubin, β-carotene, zeaxanthin and cryptocapsin . Capsanthin is not only bright in color, non-toxic and harmless, but also has antioxidant effect, and is widely used in the fields of food processing and cosmetics manufacturing. [0003] The traditional preparation process of capsanthin is as follows: first crush the capsicum to obtain capsicum powder, then extract the capsanthin in the capsicum powder through a solvent to obtain a pigment extract, and then remove the pigment extract by solvents such as ethanol and sodium hydroxide solution. The spicy taste in the medium, and finally the solution after removing the spicy taste is concentrated to obtain capsanthin. [0004] The capsanthin prepared by the pri...
