[0025]According to the mass ratio of 1:5, mix the natural zeolite with the mass fraction of 5% ammonium chloride solution, heat it in a water bath at 85°C for 8h, filter and collect the filter cake, wash it with deionized water for 5 times, and then heat it at 650°C. Calcined in a furnace for 120 minutes. After the calcination was completed, let it stand and cool to room temperature. Collect the calcined particles and mix the calcined particles with 5% hydrochloric acid in a mass ratio of 1:8. After stirring and mixing for 8 hours, filter to obtain a filter cake. Rinse with deionized water until the pH of the washing solution reaches 7.0, and dry in vacuum to obtain modified zeolite particles; mix β-cyclodextrin with deionized water at a mass ratio of 1:5, heat and stir in a water bath at 50°C to obtain a mixed solution, adjust the pH to 8.5 with a mass fraction of 3% sodium hydroxide solution to obtain an alkalized solution, and then add 2,3-epoxypropyltrimethylammonium chlori...

Abstract

The invention discloses a preparation method of an enveloping acidulant for feeds, and belongs to the technical field of feed additives. According to the preparation method disclosed by the invention, essential oil is coated with cyclodextrin, a traditional fatty acid enveloping substance is replaced, and the cyclodextrin and the essential oil slowly release and decompose in the stomach and the intestine, so that the release time of the acidulant in animal bodies is shortened, foraging of animals is promoted, and besides, the enveloping acidulant has excellent antibacterial properties, effectively prevents harmful bacteria in gastrointestinal tracts from proliferating, and promotes beneficial bacteria to propagate; besides, the enveloping acidulant is free from excessive fatty acid, effectively controls fatty acid taken in by the animals, protects the livers of the animals, shortens the growth time of the animals, and prolongs the life of the animals; zeolite is used for fixed cross-linking and adsorption modification, so that the quantity of oxygen free radicals is reduced, and the animal organisms are protected; synthetized or modified zeolite can also alleviate the oxidation process in muscular tissues, and can effectively overcome the defects that essential oil is easy to oxidize and decompose in human bodies and enveloping substances are consumed untimely, and the utilization efficiency of the acidulant is improved.

Description

technical field [0001] The invention discloses a preparation method of a coating acidifier for feed, belonging to the technical field of feed additives. Background technique [0002] Acidifiers are generally divided into inorganic acids, organic acids and their corresponding salts. The study found that among the inorganic acids, only the addition of phosphoric acid in the diet can have a positive effect on animal growth performance, while other inorganic acids such as sulfuric acid have a negative impact on animal performance. Therefore, phosphoric acid is the most commonly used inorganic acid additive in pig diets. Commercially, since the price of inorganic acids is usually lower than that of organic acids, and the combined use of inorganic acids and organic acids is generally better than a single acidifier, because they can be separated and absorbed at different positions in the digestive tract of pigs, which can improve animal performance. more attention. Organic acids...
