Description

technical field

[0001] The invention relates to a method for extracting, separating and purifying capsanthin from ripe capsicum fruit (or pericarp) by using a macroporous adsorption resin. Background technique

[0002] Capsanthin is a natural pigment widely used in food, pharmaceutical industry and cosmetics because of its safety, reliability, bright color and good thermal stability. Capsanthin is not only considered as an ideal natural food coloring agent, but also used in the coating coloring of pharmaceutical tablets. It is mainly used in the production of canned food and cakes, sauces, popsicles, ice cream, biscuits, candies, cooked meat products, artificial crab meat, feed, health care medicines, cosmetics, etc. in China. Capsicum is widely cultivated throughout our country, and there are abundant raw materials for extracting capsanthin. However, due to backward production technology, the product has high cost, low yield, poor qualit...
