Embodiment 2

[0031] After crushing 100 kg of broken rice, adding 400 kg of water to adjust the slurry, adding liquefying enzyme and glucoamylase for enzymatic hydrolysis and sterilization, the broken rice enzymatic hydrolysis solution is obtained. Weighing 250kg of broken rice enzymatic solution, adding 10kg of lactic acid-producing Lactobacillus plantarum seed solution, fermenting a single strain in liquid at 30-40°C for 60-72h, and concentrating to obtain 120-150kg of lactic acid fermentation solution. Weigh 250kg of broken rice enzymatic solution, add 15kg of citric acid-producing Aspergillus niger seed solution, and ferment for 72-96h with a single strain at 30-40°C, then concentrate to obtain 120-150kg of citric acid fermentation solution .

[0032] Mix 120-150kg of lactic acid fermentation broth, 120-150kg of citric acid fermentation broth, 30kg of lemons, 20kg of apples, 10kg of grapes, 5kg of figs, 5kg of tomatoes, 20kg of calcium formate and 50kg of silicon dioxide, and spray dry ...

Embodiment 3

[0034] After crushing 50kg corn and 50kg broken rice, adding 400kg water to make slurry, adding liquefying enzyme and glucoamylase to enzymolyze and sterilize, the corn+broken rice enzymolysis solution is obtained. In 500kg of corn+broken rice enzymatic solution, insert 3kg of lactic acid-producing Lactobacillus plantarum, 3kg of Lactobacillus acidophilus, 2kg of Lactobacillus coagulans, 5kg of citric acid-producing Aspergillus niger, propionic acid 2kg of Propionibacterium, after 60-72 hours of liquid fermentation of different product compound strains under the condition of 32-40°C, 120-150kg of compound acid fermentation broth rich in lactic acid, citric acid and propionic acid was obtained after concentration.

[0035] After mixing 120-150kg of compound acid fermented liquid, 50kg of lemons, 30kg of apples, 20kg of grapes, 50kg of calcium formate and 50kg of silicon dioxide, the mixture is dried to obtain 195-205kg of the fruit acid feed additive.

Abstract

The invention relates to a preparation method of a tartaric acid feed additive. The preparation method comprises the following steps: (1) inoculating single strains or same product composite strains to a liquid culture medium, wherein the single strains or the same product composite strains are fermented to produce a fermentation liquor mainly containing certain organic acid, and then at least two single organic acid fermentation liquors are mixed to prepare a fermented source composite acidification liquor; or inoculating different product composite strains to the liquid culture medium, wherein the different product composite strains are fermented to produce a fermentation liquor which is rich in various organic acid, directly preparing a fermetated source composite acidification liquor (2), and directly drying the fermented source composite acidification liquor to obtain the tartaric acid feed additive; or mixing the fermented source composite acidification liquor, fruits, general organic acid, organic acid salt, mineral acid and carriers to obtain a wet base of the tartaric acid feed additive. The feed additive disclosed by the invention is rich in nutrition, good in palatability and high in digestibility, and is beneficial for increasing the food consumption and the daily gain of animals, and reducing the diarrhoea rate.

Description

technical field [0001] The invention belongs to the technical field of feed, feed additives and microorganisms, and in particular relates to a preparation method of a fruit acid feed additive. Background technique [0002] China is a country with a large population and a large breeding industry. In 2014, the output value of animal husbandry reached 2.826 billion yuan, and the output of meat, poultry eggs, milk and aquatic products reached 853.05 million tons, 28 million tons, 37.25 million tons and 53 million tons respectively. Along with the development of aquaculture, the feed industry has developed at an astonishing speed. According to statistics from the Ministry of Agriculture, the national commercial feed production reached 197 million tons in 2014. Among them, 169 million tons of full-price feed, 21.51 million tons of concentrated feed, 6.4 million tons of premixed feed, including 86.86 million tons of pig feed, 90 million tons of poultry feed, 53 million tons of aq...
