Abstract

The invention relates to a method for producing lycopene oleoresin. In the method, a subcritical extraction method is adopted for extracting the lycopene oleoresin from dehydrated tomato slices, tomato dices or a byproduct for producing tomato sauce, namely tomato pomace, serving as raw materials by selecting proper fluorine hydrocarbon and a cosolvent thereof as an extraction solvent. The methodhas the advantages of simple process, small equipment investment, low environmental pollution, low energy consumption, high production efficiency in unit time and the like.

Description

technical field [0001] The invention relates to an extraction solvent for extracting and separating lycopene oleoresin by using dehydrated tomato pieces, diced tomatoes or tomato skin dregs, a by-product of tomato paste production, and an extraction and separation method thereof, and a method for refining concentrated lycopene oleoresin products. Background technique [0002] Lycopene (lycopene) is the main pigment of ripe tomato. It is an oxygen-free carotenoid with strong antioxidant activity. Lycopene can effectively inhibit the proliferation and replication of cancer cells. It is called "plant gold" by Western countries. Lycopene can protect cell DNA from free radical damage, prevent cell disease, mutation, and cancer, and can promote cell growth and regeneration. , beautify wrinkle, delay aging, protect skin health. The efficacy of lycopene in scavenging free radicals is far superior to other carotenoids and vitamin E. Its singlet oxygen quenching rate constant is 100 ...
