Problems solved by technology

As a food attractant, the flavoring agent basically has little effect on the palatability of the feed and the feed intake of livestock and poultry; the main component of the sweetener is sodium saccharin, which has a certain effect on improving the palatability of the feed, but It has a metallic bitter taste, but also has an after-bitter taste, and has no nutritional function, which limits its effect and application range to a certain extent

preparation example Construction

[0024] The present invention provides a kind of preparation method of bean wheat paste fermented feed, comprises the following steps:

[0025] 1) mixing soybeans, wheat and water, grinding, and homogenizing to obtain soybean-wheat homogeneous slurry;

[0026] 2) Inoculate the composite strains into the soybean-wheat homogeneous slurry in the step 1), and aerobically ferment at 28-32° C. for 36-48 hours to obtain fermented slurry;

[0027] Described compound bacterial classification is Aspergillus oryzae bacterial classification, rhizopus bacterial classification, Mucorus tallum and Aspergillus niger bacterial classification; The mass ratio of described Aspergillus oryzae bacterial classification, Rhizopus bacterial classification, Mucoralmyces tallum bacterial classification and Aspergillus niger classification is 100 :20~30:10~20:2~5;

[0028] 3) Mix the salt with the fermented pulp of the step 2), and after anaerobic fermentation at 38-42°C for 12-18 days, separate the soli...

Embodiment 1

[0046] Weigh 500Kg of soybeans, 50Kg of wheat and 1500Kg of water and soak for 1 hour, use a colloid mill to grind at a speed of 20,000r / min, and homogenize the obtained grinding liquid at 25MPa for 3 times to obtain soybean-wheat homogeneous slurry. The obtained soybean-wheat homogeneous slurry was sterilized at 95° C. for 40 minutes. A sterilized soybean-wheat homogeneous slurry is obtained. According to the inoculum amount of 3%, the composite strains (mass ratio of Aspergillus oryzae, Rhizopus, Mucorus tallowa and Aspergillus niger are 100:20:20:2) were inoculated into the sterilized soybean-wheat average In the plasma pulp, aerobic fermentation was carried out at 28°C for 48h (during the fermentation process, 0.20m 3 / min through sterile air, stirring at a speed of 100r / min), to obtain fermented slurry. Add salt to the obtained fermented pulp (the mass ratio of salt to fermented pulp is preferably 1:10), stir at a speed of 5000r / min for 2min, and ferment anaerobically a...

Embodiment 2

[0049] After weighing 500Kg of soybeans, 100Kg of wheat and 1000Kg of water and soaking for 3 hours, use a colloid mill to grind at a speed of 10000r / min, and then homogenize the obtained grinding liquid once at 35MPa to obtain soybean-wheat homogeneous slurry. The obtained soybean-wheat homogeneous slurry was sterilized at 105°C for 20 minutes. A sterilized soybean-wheat homogeneous slurry is obtained. Inoculate the compound strains (aspergillus oryzae strains, rhizopus strains, mucormyces tallowa strains and aspergillus niger strains in a mass ratio of 100:30:10:5) to the sterilized soybean-wheat homogeneous strains according to the inoculum amount of 3%. In the pulp, aerobic fermentation was carried out at 32°C for 36 hours (during the fermentation process, 0.30m 3 / min through sterile air, stirring at a rotating speed of 80r / min), to obtain fermented slurry.

[0050] Add salt to the obtained fermented pulp (the mass ratio of salt to fermented pulp is preferably 1:12), st...

Abstract

The invention provides a bean-wheat paste fermented feed and a preparation method and application thereof, which belong to the technical field of pig feed processing. The preparation method of the feed comprises the following steps: 1) mixing soybeans, wheat and water, grinding and homogenizing to obtain a soybean-wheat homogeneous slurry; 2) inoculating the soybean-wheat homogeneous slurry for aerobic fermentation with composite strains; 3) mixing Salt is mixed with the fermented slurry of step 2), fermented anaerobically, and the solid-liquid separation of the obtained anaerobic salt-added fermented slurry is obtained to obtain a thin liquid of soybean paste and a wet base of soy sauce; 4) mixing the wet base of soy sauce with soybean meal powder, and inoculated with Aspergillus oryzae strains for aerobic fermentation to obtain a solid fermented product of soybean paste; 5) mixing the thin liquid of soybean paste in step 3) with the solid fermentation product of soybean paste in step 4) to obtain soybean paste Sauce fermented feed. The soy-wheat paste fermented feed provided by the invention is easy to digest and absorb, and can effectively improve the production performance of piglets.

Description

technical field [0001] The invention belongs to the technical field of pig feed, and in particular relates to fermented soy-wheat paste feed and a preparation method and application thereof. Background technique [0002] China is the world's largest pig raising country. In 2017, the output value of China's animal husbandry industry reached 3.6 trillion yuan, and 689 million pigs were slaughtered. According to statistics from the Ministry of Agriculture, the national commercial feed production reached 205 million tons in 2017. Among them, 179 million tons of full-price feed, 21.51 million tons of concentrated feed, 6.9 million tons of premixed feed, including 89.74 million tons of pig feed, 90 million tons of poultry feed, 53 million tons of aquatic feed, and 8.5 million tons of cattle and sheep feed, 3.5 million tons of feed for rabbits, raccoons and pets, and more than 6 million tons of feed for piglets nationwide. It is estimated that by 2020, the national compound feed ...
