Abstract

The invention discloses a method for extracting apple polyphenol from an apple. The method comprises the following steps: (1) choosing an unmature fresh apple, breaking, taking an apple residue as theraw material; (2) putting the apple residue in ultrasonic equipment, adding an ethanol solution of 50-70 v%, wherein the solid-liquid ratio of the ethanol solution is 1:(20-33), regulating the pH to4-5, adding an antioxidant into an aqueous solution, conducting ultrasonic treatment, filtering, obtaining a crude extract; (3) processing the ultrasonic crude extract through a macroporous resin column, washing the column firstly by using the ethanol solution of 50-75 v%, then washing the column by using a sodium hydroxide solution with the mass concentration of 10-15%, collecting an eluent, adding a hydrochloric acid into the eluent, neutralizing until the pH value is 6-7.5, recovering alcohol in the eluent, concentrating and drying to prepare a semi-finished product; (4) adding the semi-finished product into an organic solvent, cleaning, removing impurities, and drying to obtain a finished product. The method for extracting apple polyphenol from the apple is reasonable in process, the extracting cycle is short, the purity of an obtained product is high, and the apple polyphenol reaches more than 82%.

Description

technical field [0001] The invention relates to the field of fruit and vegetable extraction, in particular to a method for extracting apple polyphenols from apples. Background technique [0002] Apple fruit is rich in minerals and vitamins. It is a low-calorie food that produces 60 kilocalories per 100 grams. The nutrients in apples are highly soluble and easily absorbed by the body, so they are called "living water". It is beneficial to dissolve sulfur elements, making the skin smooth and soft. [0003] Apple polyphenols is a general term for polyphenols contained in apples, which are widely found in fruits and vegetables. Apple polyphenols are a class of natural products with unique physiological and chemical activities. They have good astringency and adhesion. They can maintain collagen synthesis, inhibit elastase, assist the body to protect collagen and improve skin elasticity, thereby avoiding Or reduce the appearance of wrinkles and keep the skin showing a refined a...
