Embodiment 1

[0026] Extraction Technology of Grape Skin Polyphenols

[0027] The grape pomace was crushed through a 40-mesh sieve, and a TJ-1 microparticle ball mill was selected. The extraction solvent was 60% ethanol, the ratio of solid to liquid was 1:10, and the number of balls was 20. Place it in a ball mill jar made of zirconia, and fill it with nitrogen for 2 minutes. After rotating the ball mill at 1000rpm for 30min, it was filtered, concentrated and dried to form a finished product. After concentrating under reduced pressure, the obtained ethanol is recycled for reuse. After scavenging DPPH free radicals, OH - Free radicals, O 2- Anti-oxidation experiments such as, etc. can show that the free radical scavenging effect of the grape skin polyphenol extract with gas is 5% higher than that of the extract without gas, and the anti-oxidation effect is remarkable.

Embodiment 2

[0029] Extraction Technology of Apple Pomace Polyphenols

[0030] Grind the apple pomace into uniform particles, use an all-round planetary ball mill, use 60% ethanol as the extraction solvent, have a solid-to-liquid ratio of 1:15, and have 100 pellets. Put it in a PTFE ball mill tank and fill it with argon for 1 minute. Rotating ball milling at 600 rpm for 90 minutes, filtering, concentrating and drying to form a finished product. After concentrating under reduced pressure, the obtained ethanol is recycled for reuse. After scavenging DPPH free radicals, OH - Free radicals, O 2- According to the anti-oxidation experiments, the free radical scavenging effect of the polyphenol extract from apple skin with gas was increased by 6.1% compared with the extract without gas, and the anti-oxidation effect was remarkable.

Abstract

The invention discloses an integrated process of inflating and ball milling auxiliary organic solvent to extract polyphenols. According to the invention, a ball milling tank is filled with inert gas or nitrogen etc., so as to create an anaerobic environment for ball milling auxiliary organic solvent to extract polyphenols, so that the anaerobic environment is utilized to protect the activity of the polyphenols and thus the antioxidant activities of the polyphenols are remarkably improved. The product can be applied to the medicines and health-care products and the like. The extraction of the polyphenols provided by the invention is realized by extracting the polyphenols from the natural plants and the organic wastes rich in the polyphenols, and the natural plants and the organic wastes mainly include tea leaves, apples, pomegranates, oranges, olives, and grape skin residues and apple residues and the like.

Description

technical field [0001] The invention belongs to the technical field of extraction of natural effective components of plants, can be used for the extraction of polyphenols from natural plants and organic wastes, and particularly relates to an integrated process for extracting polyphenols from organic solvents assisted by ball milling under anaerobic conditions. Background technique [0002] In recent years, the importance of polyphenolic compounds to human health has attracted more and more attention from the scientific community. Polyphenolic compounds refer to a group of chemical substances in plants, which have anti-oxidation, strengthen blood vessel walls, promote gastrointestinal digestion, reduce blood fat, increase body resistance, and prevent arteriosclerosis and thrombosis; they can also diuretic , lowering blood pressure, inhibiting the growth of bacteria and cancer cells and helping digestion, has been widely used in food processing, medical care and daily chemical...
