Problems solved by technology

[0004] The technical problem to be solved by the present invention: Aiming at the problem that the existing acidulant prepared with organic acid or inorganic acid as the main raw material consumes too much in the stomach, it is difficult to effectively enter the intestinal tract, and the effect of preventing diarrhea in livestock and poultry is reduced, In the present invention, starch is gelatinized firstly, then pullulan is added to carry out enzymolysis and enzyme inactivation respectively, and then the products after inactivation are dissolved by boiling water, mixed with absolute ethanol and centrifuged, and the precipitate After the material is dried and pulverized, it is mixed with gelatin, carboxymethyl cellulose and other substances to prepare a slow-release carrier, and then mixed with acidic substances such as bamboo vinegar and citric acid to prepare a mixed acid, which is mixed with the slow-release carrier. And add rapeseed oil, you can get a slow-release feed acidifier

example 1

[0018] First, according to the solid-liquid ratio of 1:10, add the starch into the HAc-NaAc buffer solution with a pH of 5.5, stir and mix evenly, then add it into a three-necked flask, put the three-necked flask into a water bath, heat until the water boils, and put it in a boiling water bath Stir and mix for 50 minutes to gelatinize the starch. After gelatinization, lower the temperature of the water bath to 50°C, and add 5% pullulanase to the three-necked flask, keep stirring for 2 hours, pour out the product in the three-necked flask, and place it under a UV lamp. Inactivate the enzyme under irradiation for 20 minutes; mix the above-mentioned enzyme-inactivated product with boiling water at a mass ratio of 1:8, and stir until the solid dissolves, mix the solution with absolute ethanol at a volume ratio of 1:5, stir for 30 minutes, and centrifuge to obtain Precipitate, put the precipitate in an oven, dry at 55°C for 6 hours, crush and sieve to obtain 70 mesh powder; then sel...

[0021] First, according to the solid-liquid ratio of 1:10, add the starch into the HAc-NaAc buffer solution with a pH of 5.0, stir and mix evenly, then add it into the three-necked flask, put the three-necked flask into a water bath, heat until the water boils, and put it in the boiling water bath Stir and mix for 40 minutes to gelatinize the starch. After gelatinization, lower the temperature of the water bath to 45°C, and add 3% pullulanase in the quality of the gelatinized substance to the three-necked flask, keep stirring for 1 hour, pour out the product in the three-necked flask, and place it under a UV lamp. Inactivate the enzyme under irradiation for 15 minutes; mix the above-mentioned enzyme-inactivated product with boiling water at a mass ratio of 1:8, and stir until the solid dissolves, mix the solution with absolute ethanol at a volume ratio of 1:5, stir for 20 minutes, and centrifuge to obtain Precipitate, put the precipitate in an oven, dry at 50°C for 5 hours, cru...

[0024]First, according to the solid-liquid ratio of 1:10, add the starch into the HAc-NaAc buffer solution with a pH of 5.2, stir and mix evenly, then add it into a three-necked flask, put the three-necked flask into a water bath, heat until the water boils, and put it in a boiling water bath Stir and mix for 45 minutes to gelatinize the starch. After gelatinization, lower the temperature of the water bath to 47°C, and add 4% pullulanase to the three-necked flask, heat and stir for 1 hour, pour out the product in the three-necked flask, and place it under a UV lamp. Inactivate the enzyme under irradiation for 17 minutes; mix the above-mentioned enzyme-inactivated product with boiling water at a mass ratio of 1:8, and stir until the solid dissolves, mix the solution with absolute ethanol at a volume ratio of 1:5, stir for 25 minutes, and centrifuge to obtain Precipitate, put the precipitate in an oven, dry at 52°C for 5 hours, crush and sieve to obtain a 65-mesh powder; then sel...

Abstract

The invention relates to a preparation method of a slow-release feed acidifier and belongs to the technical field of acidifier preparation. The preparation method includes: gelatinizing starch, adding pullulanase, and respectively performing enzymolysis and enzyme deactivation; utilizing boiling water to dissolve a product obtained after enzyme deactivation, mixing with anhydrous alcohol, centrifuging, drying and smashing precipitate, and mixing with substances like gelatin and carboxymethyl cellulose to obtain a slow-release carrier; mixing acid substances like bamboo vinegar and citric acid to obtain mixed acid, mixing the mixed acid with the slow-release carrier, and adding rapeseed oil to obtain the slow-release feed acidifier. By using the slow-release feed acidifier, acidity of feed is increased, and pH in stomachs of livestock and poultry is maintained to 3.2-3.7; pathogenic bacteria are effectively inhibited and killed, and number of times of diarrhea of livestock and poultry is reduced.

Description

technical field [0001] The invention relates to a preparation method of a slow-release feed acidifier, belonging to the technical field of acidifier preparation. Background technique [0002] As the name suggests, feed acidifiers are substances that can acidify feed. There are many substances that can be used as feed acidifiers, including natural and synthetic acid preparations, inorganic acids and organic acids. In recent years, a variety of specific organic acids and inorganic acids are generally used to make compound acidifiers, so as to further improve the function of feed acidifiers. Initially, feed acidifiers are often only used as a flavor additive to improve the palatability of feed. With the development of science, the in-depth study of the absorption function of various animal digestive tracts, the generation process of feed components in the animal digestive system and the important influence of the digestive tract environment on animal growth have been increasing...
