Problems solved by technology

However, the above technology of processing tilapia scraps into fishmeal has the following disadvantages: (1) Long heating time, large amount of steam, high drying cost, and long-term high temperature will destroy nutrients
(3) In the process of fishmeal production, waste water that is difficult to treat will be produced, and many manufacturers discharge it directly without treatment, seriously polluting coastal tidal flats and offshore waters
Although some manufacturers adopt the method of heating and evaporating to recover protein in wastewater, due to the large amount of evaporated water, high energy consumption and high cost, this is the main reason why most fishmeal processing enterprises are unwilling to invest in wastewater treatment

Embodiment 1

[0022] Embodiment 1: According to the ratio of 1:1 by mass ratio, 1000 kilograms of minced tilapia leftovers and 1000 kilograms of soybean meal crushed and passed through a 60-mesh sieve were mixed, and 200 kilograms of water were added and mixed together to obtain Mixed fermented raw materials; then add 1 kg of Bacillus subtilis, 3 kg of feed yeast, 5 kg of Lactobacillus delbrueckii, 1 kg of protease, 0.1 kg of cellulase, 0.3 kg of β-glucan into the mixed fermented raw materials Carbohydrase, 0.5 kg β-mannan, 0.3 kg lipase, stir and mix evenly, start closed solid-state fermentation in the fermenter, control the fermentation temperature in the range of 30°C to 50°C, and periodically aerate the fermentation raw materials , ventilate once every 3 hours, and ventilate for 10 minutes each time. After 30 hours, no ventilate and ensure airtight and anaerobic conditions. Continue fermentation for 60 hours and end fermentation. After fermentation, the products obtained after fermentati...

Embodiment 2

[0023] Example 2: According to the ratio of 1:1 by mass ratio, 1000 kg of minced tilapia leftovers and 1000 kg of soybean meal crushed and passed through a 60-mesh sieve were mixed, and 200 kg of water were added and mixed together to obtain Mixed fermented raw materials; then add 3 kg of Bacillus licheniformis, 3 kg of Saccharomyces cerevisiae, 5 kg of Lactobacillus bulgaricus, 1 kg of protease, 0.1 kg of cellulase, and 0.3 kg of β-glucan into the mixed fermented raw materials Enzymes, 0.5 kg of β-mannan, and 0.3 kg of lipase were stirred and mixed evenly, and the closed solid-state fermentation was started in the fermenter. The fermentation temperature was controlled in the range of 30°C to 50°C. Ventilate once every 6 hours, each time for 10 minutes, no longer ventilate after 36 hours and ensure airtight and anaerobic conditions, continue fermentation for 48 hours and then end the fermentation. After the fermentation, the products obtained after fermentation are dried, crush...

Embodiment 3

[0024] Embodiment 3: According to the ratio of 0.8:1 by mass ratio, 800 kilograms of minced tilapia leftovers and 1000 kilograms of soybean meal crushed and passed through a 60-mesh sieve were mixed, and 300 kilograms of water were added and mixed together to obtain Mixed fermented raw materials; then add 5 kg of Bacillus subtilis, 3 kg of feed yeast, 5 kg of Lactobacillus delbrueckii, 1.5 kg of protease, 0.1 kg of cellulase, 0.3 kg of β-glucan into the mixed fermented raw materials Carbohydrase, 0.5 kg of β-mannan, 0.2 kg of lipase, stir and mix evenly, start closed solid-state fermentation in the fermenter, control the fermentation temperature in the range of 30°C to 50°C, and periodically aerate the fermentation raw materials , ventilate once every 3 hours, and ventilate for 10 minutes each time. After 30 hours, no ventilate and ensure airtight and anaerobic conditions. Continue fermentation for 60 hours and end fermentation. After fermentation, the products obtained after f...

Abstract

The invention relates to a method for preparing feed protein by mixed fermentation of tilapia leftovers and soybean meals, belonging to the field of feed additive preparation. The method comprises the following steps: mincing fresh tilapia leftovers, mixing the minced tilapia leftovers and crushed soybean meals at 60 meshes, adding water and uniformly mixing, and adding bacteria and enzyme to carry out solid fermentation; and drying and crushing the fermented raw materials to obtain the fermented feed protein. The fermented feed protein powder prepared by the invention is rich in small peptides and probiotics. According to the invention, the protein utilization rate is raised, the growth effect of animal is raised, the survival rate is raised. The fermented feed protein can completely replace fish meal in the feed industry, thus the feed cost is obviously reduced.

Description

technical field [0001] The invention relates to a method for preparing feed protein, in particular to a method for preparing feed protein obtained by mixed fermentation of tilapia leftovers and soybean meal, and belongs to the technical field of feed additive preparation. Background technique [0002] my country is currently the most important tilapia production area in the world. The processing of tilapia is mainly frozen fish fillets, which account for more than 80% of the total. During the processing of tilapia fillets, a large amount of tilapia leftovers will be produced, which mainly include minced fish meat, fish skin, fish scales, fish bones, viscera and fish heads, etc., accounting for about 65% of the raw fish. At present, there are more than 100 tilapia processing enterprises in the country, which produce more than one million tons of tilapia scraps every year, and these tilapia scraps are mainly used for the processing of feed protein. [0003] At present, the us...
