Abstract

The invention relates to a method for extracting and preparing physalien from wolfberry fruits, and especially relates to a method for extracting wolfberry fruit physalien. The method comprises the following steps: (1) taking, drying and crushing dried wolfberry fruits, and sieving the crushed dried wolfberry fruits by a 40-80 mesh sieve; (2) adding palmitic acid into the obtained wolfberry fruitpowder, and performing stirring; (3) carrying out microwave heating, and performing stirring during heating; (4) performing supercritical CO2 extraction to obtain crude extract of the wolfberry fruitphysalien; and (5) sequentially carrying hot alcohol washing and hot filtering on the crude extract, and collecting and drying the obtained filter cake to obtain the wolfberry fruit physalien. The method has a high product yield, and ensures the stability and purity of the product in the processing process.

Description

technical field [0001] The invention relates to a method for extracting and preparing lycopene from wolfberry, in particular to a method for extracting lycopene. Background technique [0002] Lycium barbarum is a traditional precious Chinese herbal medicine in my country, and it is also a good nourishing food material. It is widely used in traditional Chinese medicine prescriptions and modern functional health foods. Modern medical research has found that wolfberry has obvious effects on immune regulation, anti-aging, and anti-liver damage. It is generally believed that the biological activity of wolfberry is related to the biological activities of wolfberry polysaccharides and carotenoids. A large number of carotenoids are accumulated in mature fruits of wolfberry. Carotenoids, carotenoids in wolfberry dried fruit reach 1-2%, and carotenoids in wolfberry except for a small amount of β-carotene and zeaxanthin, most carotenoids are in the form of more stable carotenoid esters...
