Abstract

The invention discloses a natural antioxidant for pet food and a preparation method, the natural antioxidant is prepared from the following raw materials in percentage by mass: 3-8% of grape seed extract, 0.5-1.5% of chitosan oligosaccharide, 2-5% of pH regulator, 0.5-1% of compound emulsifier and the balance of fishskin and fishbone hydrolysate, and the sum of the mass percentages of the components is 100%. The preparation method comprises the following steps: adding the fishskin and fishbone hydrolysate and the grape seed extract into ethanol, heating and stirring, then adding the pH regulator, uniformly stirring, then adding the compound emulsifier, carrying out ultrasonic dispersion, adding the chitosan oligosaccharide, heating and stirring until the mixture is pasty, granulating, and carrying out vacuum drying. According to the natural antioxidant disclosed by the invention, the fish skin and fish bone hydrolysate, the grape seed extract and the chitosan oligosaccharide are compounded, and the natural antioxidant has the characteristics of high oxidation resistance, good thermal stability, low production cost, naturalness, no toxicity and the like, so that the comprehensive oxidation resistance is greatly improved.

Description

technical field [0001] The invention belongs to a food additive, in particular to a natural antioxidant used in pet food, and also to a preparation method of the natural antioxidant. Background technique [0002] Pet food is a food specially provided for pets and small animals. It is a high-end animal food between human food and traditional livestock and poultry feed. Its function is to provide the most basic life guarantee, growth and health for various pets. of nutrients. Antioxidants are substances added to food to prevent or delay the oxidation of food, improve the stability of food quality and prolong the storage period. [0003] However, the antioxidants used in food or feed additives in the prior art generally have poor antioxidant effects, short antioxidant times, unsatisfactory effects and low safety. For example, ethoxyquin, which is amber to light brown viscous liquid, is usually processed into powder with a carrier for use. However, its antioxidant effect will ...
