AI Technical Summary

Problems solved by technology

(2) The acidulant is released too quickly and is completely absorbed in the stomach, unable to play a role in the small intestine
(3) Large amount of addition and high cost
(4) The production and use of acidifiers will corrode machinery and transportation equipment
These technologies have defects such as complex processes and high raw material costs.

Embodiment 1

[0021] Mix formic acid and potassium hydroxide in a ratio of 1.55:1.5, slowly add formic acid dropwise to potassium hydroxide, control the reaction temperature at 50-70°C, and continue stirring for 40 minutes after the addition to complete the reaction. Then add the second batch of 1.05 parts of formic acid, control the reaction temperature at 50-80°C, stir for 1 hour, and the reaction product is in a liquid state. Then lower the temperature to 40°C, add citric acid 1 and lactic acid 1 to the reactor according to the recipe, and stir for 20 minutes until the solid citric acid is completely dissolved, so as to avoid the volatilization loss of lactic acid as much as possible, and the obtained liquid mixture is a liquid mixed acidulant.

[0022] Excipient stage: add the liquid mixed acidulant to the excipient silicon dioxide, stir constantly, and the final white powder is the product solid acidulant. The main component of the obtained product is a mixture of lactic acid, citric a...

Embodiment 2

[0025] Mix formic acid and potassium carbonate at a ratio of 1.5:1.45, slowly add formic acid dropwise to potassium carbonate, control the reaction temperature at 50-70°C, and continue stirring for 40 minutes after the addition to complete the reaction. Then add the second batch of 1.0 parts of formic acid, control the reaction temperature at 50-80° C., stir for 1 h, and the reaction product is in a liquid state. Then lower the temperature to 40°C, add citric acid 0.9 and lactic acid 1.1 to the reactor, and stir for 20 minutes until the solid citric acid is completely dissolved, so as to avoid the volatilization loss of lactic acid as much as possible, and the obtained liquid mixture is a liquid mixed acidulant.

[0026] Excipient stage: add the liquid mixed acidulant to the excipient silicon dioxide, stir constantly, and the final white powder is the product solid acidulant. The main component of the obtained product is a mixture of lactic acid, citric acid, formic acid and t...

Embodiment 3

[0029] Mix formic acid and potassium bicarbonate at a ratio of 1.6:1.55, slowly add formic acid dropwise to potassium bicarbonate, control the reaction temperature at 50-70°C, and continue stirring for 40 minutes after the addition to complete the reaction. Then add the second batch of 1.1 parts of formic acid, control the reaction temperature at 50-80°C, stir for 1 hour, and the reaction product is in a liquid state. Then lower the temperature to 40°C, add citric acid 1.1 and lactic acid 0.9 to the reactor, and stir for 20 minutes until the solid citric acid is completely dissolved, so as to avoid the volatilization loss of lactic acid as much as possible, and the obtained liquid mixture is a liquid mixed acidulant.

[0030] Excipient stage: add the liquid mixed acidulant to the excipient silicon dioxide, stir constantly, and the final white powder is the product solid acidulant. The main component of the obtained product is a mixture of lactic acid, citric acid, formic acid ...

Abstract

The invention discloses an acidulant for feed. Effective components of the acidulant for feed comprise the following ingredients according to parts by weight: 1.05-1.15 parts of formic acid, 1.45-1.55 parts of formate, 0.9-1.1 parts of lactic acid, 0.9-1.1 parts of citric acid and an appropriate amount of excipient, such as silicon dioxide and the like. The acidulant of the invention has simple preparation process, low raw material cost and low absorptivity in stomach, as a result, a majority of the acidulant can give play to bacteriostatic action in rear section of alimentary canal.

Description

technical field [0001] The invention relates to a feed additive and a preparation method thereof, in particular to an acidifier for feed and a preparation method thereof. Background technique [0002] Acidifier is a kind of non-nutritive feed additive, which can increase the acidity of feed, inhibit the growth of harmful bacteria, improve the environment of animal digestive tract, and improve the growth performance of animals. [0003] Acidifiers mainly include single acidifiers and compound acidifiers, and single acidifiers are divided into organic acids and inorganic acids. The currently used inorganic acidifiers are mainly phosphoric acid; the organic acidifiers mainly include citric acid, fumaric acid, lactic acid, propionic acid, malic acid, sorbic acid, formic acid, acetic acid and the like. Composite acidifier is made by compounding two or more single acidifiers according to a certain ratio. The composite acidifier can be used together with several acids, or it can b...
