Embodiment 1

[0108] A kind of preparation of composite liquid feeding acidulant comprises the following steps:

[0109] Grind 140kg of broken rice and 10kg of corn, add 1050kg of water to adjust the slurry, add 0.15-0.20kg of liquefaction enzyme and glucoamylase to liquefy and saccharify when the temperature rises to 95°C, and obtain 1200kg of slag-containing sugar liquid, sterilize and cool at high temperature, and insert 20kg of citric acid-producing strains were aerobically fermented at 22-28°C for 60-72 hours, and then 30kg of citric acid residue wet base and 1150-1165kg of citric acid fermentation broth were obtained through solid-liquid separation;

[0110] After 1150-1165kg of citric acid fermentation broth is evaporated and concentrated, 290-320kg of citric acid concentrate is prepared;

[0111] Grind 100kg of corn, add 250kg of water to make slurry, add liquefaction enzyme and glucoamylase to enzymatically hydrolyze, and obtain 350kg of saccharified liquid with slag. Through soli...

Embodiment 3

[0126] A kind of preparation of lactic acid type liquid feeding acidulant comprises the following steps:

[0127] Crush 100kg of broken rice, add 400kg of water to adjust the slurry, add liquefying enzyme and glucoamylase for enzymatic hydrolysis, and obtain 500kg of saccharified liquid with slag. Through solid-liquid separation, 18kg of sugar residue wet base and 482kg of residue-free saccharification liquid were obtained.

[0128] In 482kg of slag-free saccharification liquid, high-temperature sterilization and cooling, 20kg of lactic acid-producing lactic acid bacteria seed solution was inserted, and under the basic constant conditions of continuous flow of calcium hydroxide solution, temperature 42-45°C, and fermentation pH: 7, carried out After anaerobic fermentation for 48-60 hours, 482 kg of crude lactic acid fermentation liquid was obtained, and after solid-liquid separation, lactic acid residue and lactic acid fermentation liquid were obtained. Add 60kg of 20% dilute...

Abstract

The invention relates to a preparation method of a liquid feed acidulant. The preparation method comprises the following steps of respectively inoculating organic acid strains into liquid culture mediums, and then performing fermentation for producing liquid fermentation source organic acid; omitting a decoloration ion-exchange technology, directly performing evaporation and concentration on the liquid fermentation source organic acid, and mixing the evaporated and concentrated liquid fermentation source organic acid with one or more of feed inorganic acid, organic acid salt, saccharide, Chinese herbal medicines and vitamins so as to obtain the liquid feed acidulant. A feed prepared by the preparation method disclosed by the invention contains nutrients including lactic acid, citric acid, other organic acid, saccharide and the like, and has the characteristics of being capable of resisting diarrhoea, quickly dissolving in water, being high in drinking attraction, being high in eating attraction and the like.

Description

technical field [0001] The invention belongs to the technical fields of feed, enzyme preparations and microorganisms, and in particular relates to a preparation method of a liquid feeding acidifier. Background technique [0002] In recent years, food safety and environmental pollution have been widely concerned by governments at all levels in various countries, which are related to the health and life safety of the people. The safety of animal products requires that the feed has no drug residues, and the environmental protection requires that the feed has low pollution. In the past, we talked about "effective and safe" feed, but now the Ministry of Agriculture has repeatedly emphasized "safe, effective and low pollution". As we all know, since the advent of antibiotics, their use in livestock and poultry to prevent diseases and stimulate growth has indeed received good results. However, with the passage of time, the defects of antibiotics have been fully exposed: first, ant...
