Abstract

The invention discloses a natural oxidation inhibitor containing plant extracts, and a preparation method and application of the natural oxidation inhibitor, as well as a processing method of minced pork. The natural oxidation inhibitor is prepared by directly and uniformly mixing the following raw materials in parts by weight: 10-15 parts of a sesame-send cake meal extract, 40-75 parts of a grape seed meal extract, and 15-45 parts of a Huangshan maofeng tea extract according to a compounding ratio. The natural oxidation inhibitor is added to the processing course of the minced pork, so that the oxidation of fat and protein in the minced pork can be notably restrained.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a natural antioxidant containing plant extract capable of inhibiting fat oxidation and protein oxidation of minced pork, a preparation method and application thereof, and a processing method of minced pork. Background technique [0002] Lipid oxidation and protein oxidation are one of the main reasons leading to the deterioration of the quality of meat and its products. Lipid oxidation can cause discoloration, odor, texture deterioration and loss of nutrients in meat and its products. Protein oxidation can affect the tenderness, water holding capacity and nutritional value of meat, thus affecting consumers' acceptance of products. [0003] Free radical chain reaction is one of the main causes leading to fat oxidation and protein oxidation. Antioxidants are good scavengers of free radicals, which can block free radical chain reactions, thereby inhibiting lipid oxidation a...
