Preparation method of capsanthin

Abstract

The invention relates to a method for preparing water-soluble capsanthin by a physical and chemistry method by taking oil-soluble natural capsanthin resin as a raw material. The method comprises the processes of hydrolysis reaction, filtration, extraction separation, evaporation, spray-drying and the like. The method comprises the following steps: firstly taking safe solvent food-grade ethanol asa solvent, performing the hydrolysis reaction with a potassium hydroxide solution in a reaction kettle, controlling the temperature and continuously stirring, so that the hydrolysis rate reaches 95 percent or above through thin layer chromatography detection; then performing filtration and separation, repeatedly extracting the food-grade ethanol for a filter cake for multiple times, combing filtrates, performing reduced-pressure evaporation and concentration and recovering the ethanol to prepare a water soluble natural capsanthin solution; then mixing the water soluble natural capsanthin solution with a solution of an excipient, homogenizing, controlling the temperature and spray-drying to prepare water soluble capsanthin powder. The method provided by the invention is simple and reliablein principle, high in yield and good in quality and can be used as an additive in medicines, food and cosmetics.

Description

Technical field: [0001] The invention belongs to the technical field of food chemical industry, and relates to a method of using capsanthin resin as raw material, adopting physical and chemical methods, through hydrolysis reaction, filtration, extraction, separation, refining, spray drying and other processes to realize the production of water-soluble capsanthin Production, especially a preparation method of capsanthin. technical background: [0002] Capsicum is a very familiar plant and is cultivated all over the country. Capsanthin is a natural pigment extracted from peppers. Its main components are red pigments such as capsanthin and capsanthin, and yellow pigments such as capsanthin, zeaxanthin and cryptoxanthin. The content of capsanthin and capsanthin accounts for more than 60% of the content of the pigment components, and the rest are very little. Its appearance is orange-red oily liquid. Capsanthin is mainly composed of higher fatty acid esters of capsanthin. The...

Problems solved by technology

At present, domestically extracted capsanthin resin is mainly used in a fat-soluble state, or in the form of a water-dispersible product through the action of a food emulsifier, thus limiting the application range of capsanthin

[0004] At present, there are many oily capsicum products on the market, and its production methods have mature technologies and methods. However, due to the relatively small range of use of oily capsicum, and it is troublesome to use, in many cases, oily capsicum Soluble capsicum pigment cannot be directly applied, especially in the fields of medicine, food and cosmetics, the use of oil-soluble pigments can easily cause adverse effects, and even lead to a decrease in the quality factor of the added product, so the characteristics of capsicum pigment are changed to make it water-soluble Sexual products, expanding its application field has become one of the technologies actively explored in the industry today
