Method for extracting capsorubin and capsaicin from chillies

Abstract

The invention relates to a method for extracting capsorubin and capsaicin from chillies. The method is characterized by comprising the following steps: grinding chillies, using inorganic alkaline liquor containing sodium ions and / or potassium ions as the extractant to extract capsaicin from chilli powder through the solvent method, and extracting capsorubin from the residues of the chilli powder. By adopting the method in the invention, the bioactivity of capsorubin can be effectively protected, the extraction rate of capsorubin can be increased by 15%, the extraction rate of capsaicin can be increased by 5%, the extraction time can be shortened from about 5.5h-10 hours of the prior art to 40 minuntes-3 hours and the extraction efficiency can be obviously increased; the product has high purity and has no peculiar smell or has slight peculiar smell; and the color value of the capsorubin extracted by the method is increased by 20% compared with that of the capsorubin which is extracted by the solvent method of the prior art. The method in the invention has the advantages of high yield of the extracted target product, short cycle, high efficiency, good quality and easy operation process and low carbon, is environmental-friendly and economic and is suitable for industrial mass production.

Description

technical field [0001] The invention relates to extracting and separating natural substances from plants, in particular to a method for extracting capsanthin and capsaicin from capsicum. Background technique [0002] Capsanthin, capsanthin, is a natural carotenoid without any toxic and side effects on the human body. It has been approved by organizations such as the US FDA, the UK, Japan, EEC, FAO / WHO and China GB for unlimited use. Natural food additives. Because of its anticancer and cosmetic effects, it is widely used in the fields of food, medicine, cosmetics and children's toys. Capsaicin is a raw material for the production of analgesics and detoxification drugs in the pharmaceutical industry, and a raw material for the production of tear gas weapons in the military. It has an extremely wide range of applications and is known as "soft gold". Our country is rich in capsicum resources and there are many kinds.

Problems solved by technology

To extract capsanthin and capsaicin from peppers, the dry red pepper skin seeds are generally separated, and the pepper skins are ground into chili powder, while chili powder has a fibrous structure with flakes and unevenness, and pigments and other fat-soluble components exist in It is difficult to dissolve in the fibrous tissue. The existing technology mainly uses traditional high temperature and high concentration organic solvent extraction, which greatly damages the activity of active ingredients, organic solvent residues, and low extraction rate.

[0004] The product extraction rate of the oil-soluble method is low, the separation of oil and pigment is difficult, and it is difficult to obtain products with high color value

[0005] The traditional extraction method usually adopts the solvent method. Briefly speaking, the process is to use organic solvents such as propanol, ethanol, ether, chloroform or trichlorethylene as extraction agents to soak paprika to extract capsanthin and capsaicin, and then extract The liquid is concentrated into crude capsicum oleoresin, which is concentrated under reduced pressure to obtain capsanthin without spicy taste; according to the different extraction agents selected, some need to extract capsanthin and capsaicin in chili powder by heating and refluxing; The product yield is low, the purity is poor, and it has peculiar smell and solvent residue, and the quality is poor. If it is necessary to use heating and reflux to extract capsanthin and capsaicin, it will increase energy consumption and increase production costs.

The patent application number "200710300024.9" discloses a process for extracting and separating capsaicin, capsanthin and capsicum essence from red peppers. It uses ethanol as the extraction solvent and adopts a three-stage extraction method to prepare capsaicin, capsaicin, Capsicum extract and capsanthin are three kinds of extracts, but they need to be heated and refluxed to extract the target, which increases energy consumption and increases production costs; and the extraction rate is not high, the extraction cycle is long, and the efficiency is low

[0006] However, the supercritical fluid extraction method has a large investment in one-time equipment, and the equipment belongs to the third type of pressure vessel. Due to the limitation of the processing capacity, the output is low, the operating cost is high, and it still cannot completely get rid of the use of organic solvents. The industrial development is more difficult. , it is difficult for general enterprises to adopt, making this method difficult to popularize and apply

[0007] In the prior art, capsaicin and alkali are reacted to generate solid saponified products through hydrolysis to achieve the purpose of removing capsaicin substances and extracting capsanthin products, but because this type of method can only obtain a single capsanthin product, Capsaicin can not be well utilized, and its benefits are very poor when used in production
