specific Embodiment approach 1

[0006] Embodiment 1: In this embodiment, a method for extracting apple polyphenols is characterized in that the steps of the method for extracting apple polyphenols are as follows: 1. Extraction of apple polyphenols: firstly carry out the screening of apples, select fresh apples and crush them, Make a beating, add apple pulp and acetone with a concentration of 90% in a ratio of 1:5, extract with a strong electric field for 20 to 30 minutes to obtain an extract containing apple polyphenols, and finally use a decanter centrifuge at 1500 to 2000r / min The solid-liquid separation was carried out at a high speed, the extract and residue were separated, and the residue was added into the aqueous solution at a ratio of 1:5, and the strong electric field extraction and centrifugation were continued for 3 consecutive extractions, the residue was removed, and the extract was combined. 2. Concentration: Concentrate the apple polyphenol extract with a vacuum scraper film, the concentration ...

specific Embodiment approach 2

[0007] Embodiment 2: This embodiment is different from Embodiment 1 in that it is characterized in that the extraction electric field strength in step 1 is 60-90 kilovolts per square centimeter, the number of high-voltage electric field pulses is 900 times, and the pulse frequency is 600-650 Hz. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0008] Embodiment 3: This embodiment is different from Embodiment 1 in that it is characterized in that the solid content in the concentrated solution in step 2 is 45% to 50%. Others are the same as in the first embodiment.

Abstract

The invention relates to an apple polyphenol extracting method, in particular to an apple polyphenol preparation method. The invention solves the problems of low extraction rate, poor activity and complex production process of the traditional apple polyphenol extracting method. The apple polyphenol extracting method comprises the following steps: selecting apples, crushing, pulping, extracting by a highfield, separating extract liquor by an ultracentrifuge, removing residues, concentrating by a vacuum wiped thin film, drying by vacuum freeze drying equipment to obtain freeze dried powder of apple polyphenol, and respectively adding blueberry anthocyanin, vitamin C and seabuckthorn flavone to prepare a nutrition enhancer. The apple polyphenol prepared by the invention is a natural extract without side effects on a human body, has functions of strengthening the immunity, resisting tumors, reducing blood fat, resisting coagulation and thrombus, reducing the weight, beautifying the skin and the like, and can be applied to the fields of foods, health care products, cosmetics, medicines, biochemical industry and the like.

Description

technical field [0001] The invention relates to a method for preparing apple polyphenols. Background technique [0002] Apple polyphenols are special active factors of apples, which have the functions of anti-tumor, lowering blood fat, lowering blood pressure, anti-thrombosis, weight loss, and anti-oxidation. It can be used in food, health products, medicine and other fields. [0003] At present, apple polyphenols can be widely used in the production of food, medicine, health care products and cosmetics, and its market prospect is very broad. Although there are many studies on apple polyphenols, the extraction methods of apple polyphenols are mainly ultrasonic method and reflux extraction method. During the process of extracting apple polyphenols by ultrasonic method, a large number of free radicals will be generated, which will destroy the physiological activity of apple polyphenols. , and the reflux extraction method is a high-temperature extraction technology, which wil...
