Abstract

The invention relates to the technical field of lycopene extraction, in particular to a method for ultrasonic countercurrent extraction of lycopene. The steps of the method include cleaning tomatoes; squeezing juice with a press machine; drying the tomato pulp obtained by squeezing; drying the peels in a vacuum; crushing the dried peels; ; Use alcohols to flocculate and precipitate concentrated solution to achieve refining effect, obtain high-quality lycopene, and obtain tomato juice and tomato by-products. Based on the ordinary solvent method, this method adopts the combination of continuous countercurrent and ultrasonic extraction technology. Through the action of ultrasonic, the speed of osmotic dissolution and diffusion in the extraction process is accelerated, and the extraction time is shortened. It has strong penetrating power and is suitable for thermal extraction. The extraction of sensitive and photosensitive substances has high extraction efficiency, low energy consumption and solvent consumption, low cost, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of lycopene extraction, in particular to a method for ultrasonic countercurrent extraction of lycopene. Background technique [0002] Lycopene is a fat-soluble natural pigment. It is the most effective anti-oxidation and anti-radiation active substance known at present. It has strong anti-oxidation and ability to eliminate free radicals, can slow down atherosclerosis, prevent The oxidation of density cholesterol can effectively prevent the occurrence of cardiovascular diseases, and it also has the function of filming gene mutations and preventing malignant tumors. It is soluble in fats and oils and turns red. It is a better colorant in food Therefore, lycopene is a natural, green functional health food for both medicine and food, which is widely used in medicine, health products, food, cosmetics and other fields. Lycopene is mainly found in fruits such as tomatoes, watermelons, and grapes, and it is a caro...
