Problems solved by technology

[0003] However, the main problem in the existing apple polyphenol extraction technology is that "polyphenol oxidase can oxidize polyphenols and reduce the yield of polyphenols". In view of the fact that pressure can effectively enhance the cavitation effect of ultrasonic waves, the combination of pressure and ultrasonic waves can Effectively reducing enzyme activity and other factors, combining pressure and ultrasound to assist solvent extraction can effectively increase the yield of apple polyphenols

Abstract

The invention discloses an apple polyphenol extraction method, and belongs to the field of plant extraction. The method comprises the following steps: 1, preparing cleaned pomace as a raw material; 2, extracting: putting the pomace in a pressure ultrasonic device, adding a 50-70% ethanol solution according to a material-to-liquid ratio of 1:10-15, adjusting the pH value to 3.5-4.0, carrying out pressurization ultrasonic treatment at a working temperature of 55-85DEG C under a pressure of 0.30-0.45MPa, an ultrasonic frequency of 25KHz and an ultrasonic power of 160-230W for 9-20min, and taking out the obtained material solution after the ultrasonic treatment is completed; and 3, carrying out membrane filtration: filtering the material solution by using a membrane filtration device to obtain a clarified and transparent apple polyphenol dialysate, wherein the membrane used in the invention is an ultrafilter membrane, a microfiltration membrane or a nanofiltration membrane. The method improves the pectin feeling and the quality indexes, allows high quality apple polyphenols to be produced, and improves the utilization rate of the apple pomace raw material by using present pectin production devices.

Description

technical field [0001] The invention relates to the technical field of plant extraction, in particular to an extraction method of apple polyphenols. Background technique [0002] Many studies in recent years have confirmed that the oxidative damage caused by free radicals is closely related to the occurrence of some chronic diseases such as cancer and cardiovascular and cerebrovascular diseases. Therefore, it is an inevitable trend in the development of health care, medicine and other fields to find natural, efficient and low-toxic antioxidants and free radical scavengers from plants. Judging from the current research, most of the natural plant antioxidants are polyphenolic substances, among which tea polyphenols, pine bark extract and grape seed extract are widely used, and their main components are proanthocyanidins substance. Since the French scholar Jacques Masquelier first discovered that proanthocyanidins have antioxidant effects in 1951, the French scholar Renaud pu...
