Problems solved by technology

However, since the content of phytoene and phytoene in natural products is very low, and their properties are unstable, they are very sensitive to alkali, light and oxygen, so whether it takes too long to separate or steps Too much will lead to product loss and low yield

Abstract

The present invention provides a method for extracting hexahydrophytoene and phytoene quickly, efficiently and safely——enzymatic hydrolysis microwave-assisted edible oil extraction method for hexahydrophytoene and phytoene, which promotes polyhydrophytoene Application of lycopene in processed food, medicine and health products. The invention uses edible oil as the extractant, has good safety, is easy to recycle and handle, and reduces equipment anticorrosion and pollution control treatment costs. The invention uses immobilized cellulase and pectinase to degrade, which is beneficial to destroy the cellulose and pectin in the tomato, so that the phytoene is fully overflowed, and combined with the microwave extraction technology, the speed of osmotic dissolution and diffusion in the extraction process is accelerated , shorten the extraction time, increase the extraction yield, and make the extraction rate of lycopene reach 5~13%, which provides a source of raw materials for the development of new products based on phytoene and phytoene.

Description

1. Technical field [0001] The invention belongs to the field of food processing and relates to a method for extracting phytoene and phytoene from tomatoes in a safe, efficient and high-purity manner. 2. Background technology [0002] Lycopene is a carotenoid that has a bright red color. Naturally occurring lycopene and its precursors are mainly in the all-trans structure, and the all-trans structure will undergo cis-trans isomerization after heating or other treatment methods. Studies have found that lycopene has antioxidant activity, anti-aging activity, and the activity of absorbing visible light and ultraviolet rays to reduce sun damage. Whether it is used as a health product or as a pigment, it has attracted widespread attention. Hexahydrophytoene and phytoene are intermediate products in the natural synthesis pathways of carotenoids and lycopene, and their molecular formulas are C 40 h 62 and C 40 h 64 . Phytoene has five double bonds conjugated to each other whi...
