Abstract

The preparation method of lycopene richly containing cis-isomer is characterized by that the tomato paste and edible oil are heated in a reactor and stirred, then filtered to obtain edible oil clear liquor and tomato paste residuum, and the tomato paste residuum and edible oil are undergone the process of 1-6 above-mentioned circulating operations to obtain edible oil clear liquor, heated and evaporated, condensed at -0.05 to -0.1 MPa and refluxed so as to obtain the invented product. It has the advantages of simple technological process, no pollution, easily available raw material and low cost, etc.

Description

(1) Technical field [0001] The invention relates to a preparation method of lycopene rich in cis-isomers. Specifically, the cis-isomers in lycopene, which is a raw material of tomato sauce or tomato sauce residue, are only 5.3%. The cis content range of the cis isomer in lycopene is as high as 11.5-48.1%, which belongs to the food deep processing technology. (2) Background technology [0002] Lycopene is widely found in plants. Ripe tomatoes, watermelons, carrots, red grapefruits and other red fruits have more content. At the same time, it is also widely found in various organs and tissues of the human body, including blood, adrenal glands, testicles, and liver. Lycopene, etc. contain more lycopene. Since lycopene is a fat-soluble natural pigment, it is very popular as a food additive, and a large amount of evidence from epidemiological studies has confirmed that lycopene has a role in preventing certain cancers. Therefore, the research on lycopene has gradually attracted a...
