Abstract

The invention relates to a lycopene product with rich cis-isomer and a preparation method thereof, belonging to the technical field of the production of functional food ingredients. The preparation method of the invention uses lycopene oleoresin or purified lycopene as raw material and adopts the 'short-time hot reflux-low-temperature standing and crystallization-crystal-removing-solvent-recycling from mother solution' technology to obtain high cis-lycopene product and high-purity all-anti-lycopene product. The preparation method of the invention has the advantage that high cis-lycopene product and high-purity all-anti-lycopene product can be obtained at the same time; the cis-isomer in the high cis-lycopene product is up to 60-95%, the purity of the all-anti-lycopene in crystal is up to over 95%. Production process is simple, the production efficiency is high, and the contrast advantage is obvious.

Description

technical field

[0001] A lycopene product rich in cis-isomers (hereinafter referred to as high-cis lycopene product) and a preparation method thereof. The present invention uses lycopene crude extract (also known as lycopene oleoresin) or purified lycopene as raw material, through "short-term heat reflux - standing at low temperature for crystallization - removing crystallization - recovering solvent from mother liquor" The invention discloses a method for preparing a lycopene product rich in cis-isomers, which belongs to the technical field of functional food ingredient production. Background technique

[0002] Lycopene is a linear polyunsaturated olefin composed of eleven conjugated double bonds and two non-conjugated double bonds, which has a strong effect of quenching singlet oxygen and scavenging free radicals in the body. A large number of in vivo and in vitro test results show that lycopene can delay the aging of the body, inhibit the oxidative damage of lymphocyte D...
