Composition of ester type catechin and vitamin C palmitate for breeding pigeons and preparation method of composition

Abstract

The invention belongs to the technical field of feed additives, and particularly relates to a composition of ester type catechin and vitamin C palmitate for breeding pigeons and a preparation method of the composition. The composition is prepared from catechin crude extract containing EGCG, vitamin C palmitate, a composite self-emulsifying agent, curing dispersing powder and a filling auxiliary material. In the preparation of the composition, the stability and the absorbability of the catechin can be effectively ensured by utilizing an encapsulation effect formed by the vitamin C palmitate and the composite self-emulsifying agent, an efficient synergistic effect is further achieved, the bioavailability of ECGC is remarkably improved, the instability problem of conventional catechin is solved, the biological efficiency of the ECGC is remarkably improved, the usage amount is lower, and the composition is suitable for industrial production. Raw materials used in the composition are all food-grade or feed-grade raw materials, no other chemical preparations are added, and the composition can be used as an antibiotic-replacing functional additive for improving the oxidation resistance and immunity of the breeding pigeons and improving the egg quality.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a composition of ester-type catechin and vitamin C palmitate for pigeon breeding and a preparation method thereof. Background technique [0002] As a traditional delicacy material, pigeon has high nutritional value. It is not only a precious delicacy, but also a high-end nourishing product. It is known as "one pigeon wins nine chickens". With the development of my country's economy and the improvement of living standards, more and more attention has been paid to the "three highs" caused by traditional high-fat and high-cholesterol diets. Healthy, low-fat, and low-cholesterol diets are favored, coupled with diversified consumption, Thereby the pigeon industry has developed by leaps and bounds, and the food of various characteristic pigeons is put on the homes of ordinary people. However, with the expansion of the scale of the pigeon industry, the popularization of commercia...

Problems solved by technology

Patent CN202011067831.2 discloses the composition, preparation method and application of a feed additive that can increase pigeon feed intake, reduce pigeon diarrhea rate and improve pigeon immune performance; patent CN201910225323.3 discloses an antiviral feed for young meat pigeons Additives and preparation methods; patents with Chinese herbal medicine as the main ingredient have certain formula complexity and their effectiveness has obvious time-dependence and dose-dependence. It requires large doses of long-term application to achieve the effect. At present, with the purchase price of Chinese herbal medicine Continuously increasing, the on-site use cost of the above-mentioned patented technology constitutes a huge economic pressure especially for the poultry industry

[0004] There is also a related patent CN201911279534.1 which discloses a kind of gallocatechin and its use in the preparation of intestinal pathogenic bacteria drugs and feed additives; For the application of pig feed additives and the prepared pig feed, the above-mentioned patented technologies for catechin-type feed additives are mostly directly added after simple processing, which ignores the most restrictive factors that restrict the bioavailability of catechins. That is, catechin is a polyphenolic substance, which has the problems of poor stability and easy oxidation failure. Although the stability of ester-type catechins such as EGCG is better than that of conventional non-ester-type catechins, a considerable amount of effectiveness still occurs. Loss, the effect can only be guaranteed by increasing the dosage. At the same time, considering that the phenolic hydroxyl group of catechin is easy to react with various active groups on the protein to form precipitates, and the reactants have anti-nutrient absorption effects, so especially adding large doses Catechin additives often lead to feed nutrient loss or aggravate side effects such as malnutrition
