Abstract

The invention discloses a preparation method of a polysaccharide type compound acidifier for a feed, and belongs to the technical field of acidifiers. The technical scheme adopted by the invention lies in that the preparation method comprises the following steps: step 1, preparing a component A from the following components in percentage by weight: 8-13% of phosphoric acid, 7-10% of citric acid, 12-14% of fumaric acid, 9-15% of lactic acid, 2-6% of benzoic acid, 1-1.5% of formic acid, 1-4% of acetic acid, 2-4% of propionic acid and the balance deionized water; step 2, smashing and sieving radix bupleuri, adding a surfactant aqueous solution, performing heating reflux, and performing cooling to obtain cooling liquid; and 2.1, centrifuging the cooling liquid, taking supernatant, and performing extracting with saturated n-butyl alcohol to obtain a radix bupleuri extracting solution, namely a component B; and 3, mixing the component A with the component B according to a mass ratio of 1: (3-4), adding cane molasses, and performing uniform stirring to obtain the compound acidifier. The preparation method is of great significance to intestinal health of animals and prevention and treatment of intestinal diseases of the animals.

Description

technical field [0001] The invention relates to the technical field of acidulants, in particular to a preparation method of a polysaccharide compound acidulant for feed. Background technique [0002] Acidifier is a very common feed additive in the feed industry. It is mainly used in the diet of young animals to adjust the environment in the digestive tract. It refers to a class of substances added to feed to supplement the insufficient secretion of gastric juice in young animals and reduce the pH value in the stomach. It is a class of substances mainly composed of one or more acids and acid salts, used to reduce the acidity of livestock and poultry diets and the pH value of the gastrointestinal tract. Including inorganic acids, organic acids and their salts. As an efficient, pollution-free, and residue-free feed additive, acidifiers are listed as new green feed additives along with enzyme preparations and flavoring agents, and their applications are becoming more and more ...
