Method for extracting apple polyphenol by using cutinase, and application thereof

Abstract

The invention discloses a method for extracting apple polyphenol by using cutinase. The cutinase has the following characteristic that: the cutinase can be provided for catalyzing cutin hydrolysis in an aqueous solution or an ethanol solution. With the present invention, the cutinase is provided for producing the apple polyphenol through adopting the characteristic of the cutinase. According to the present invention, the apple polyphenol can be extracted at a low temperature through a assistance of the cutinase, organic solvents are not required or consumptions of the organic solvents are reduced such that a more green environmental-protection and energy-saving production for the apple polyphenol is provided.

Description

technical field

[0001] The invention relates to a method for extracting apple polyphenols from apple peels, which involves extracting apple polyphenols from apple peels by using cutinase in a water or alcohol-containing system. Background technique

[0002] Apple polyphenols have many important physiological functions and are an important class of natural bioactive substances. Due to the functions of anti-aging, anti-cancer, anti-oxidation, scavenging free radicals, preventing vitamin deterioration, anti-radiation and hindering ultraviolet absorption, apple polyphenols are used in medicine, food, cosmetics and other fields. Previous studies have shown that the polyphenol content in apple peel is much higher than other parts of apple. However, during the production of apple juice, cider, etc., apple pomace is produced. Some of these skin residues are buried directly as garbage, causing pollution to the environment; some are used to produce feed, and the protein content in ...
