Microwave-assisted method for extracting peanut coat haematochrome

Abstract

The invention discloses a microwave-assisted method for extracting peanut coat haematochrome. Natural pigments are strongly demanded in markets at home and abroad. Haematochrome is a pure nature pigment, can be widely used for coloring food and has medical treatment functions; resveratrol included in the haematochrome and also known as resveratrol has antiplatelet aggregation and anti-inflammatory, anti-allergic, antithrombotic and atherosclerosis effects, has preventive and therapeutic effects on coronary heart disease, ischemic heart disease and hyperlipidemia and also has antioxidant effect and effects of scavenging free radical and inhibiting tumor. According to the technical scheme adopted by the invention, a microwave-assisted method for extracting peanut coat haematochrome is characterized by comprising the following steps of: preparing raw materials, carrying out microwave-assisted extraction, carrying out secondary extraction, adopting a membrane filtering method, concentrating in vacuum, freezing and drying to obtain the product.

Description

technical field [0001] The invention relates to a method for extracting red pigment from peanuts assisted by microwaves, and belongs to the field of biological extraction. Background technique [0002] Food coloring is a kind of food used for coloring food additive , widely used in food, daily chemical, pharmaceutical and other industries. The pigments currently used are mainly synthetic pigments, which are low in cost, but have different harms to the human body, especially the consequences of carcinogenicity, teratogenicity and mutagenesis, which have aroused great concern. Developed countries have legislated to prohibit the use of synthetic pigments. , my country has also banned the use of synthetic pigments in food, cosmetics, medicine and other industries. Natural pigments are pigments directly extracted from plants, which not only have no toxic side effects, but also have certain nutritional value. Natural pigments have become an inevitable trend to replace synthetic pi...

Problems solved by technology

The pigments currently used are mainly artificial synthetic pigments, which are low in cost, but have different harms to the human body, especially carcinogenic, teratogenic, and mutagenic consequences, which have aroused great concern. Developed countries have legislated to ban the use of artificial synthetic pigments , my country has banned the use of synthetic pigments in food, cosmetics, medicine and other industries. Natural pigments are pigments directly extracted from plants. They not only have no toxic side effects, but also have certain nutritional value. It has become an inevitable trend for natural pigments to replace synthetic pigments. , the shortage of natural pigments in the international market

[0003] The demand for natural pigments is strong at home and abroad. Peanut red pigment is a pure natural pigment. It is not only widely used in food coloring, but also has medical treatment effects. and anti-inflammatory, anti-allergic effects; antithrombotic effect; anti-atherosclerosis and coronary heart disease, ischemic heart disease, hyperlipidemia prevention and treatment; anti-oxidation, free radical scavenging effect; tumor inhibition effect, domestic and foreign Although there is a small amount of research, there is no report on the production of the product
