Problems solved by technology

[0007] The purpose of the present invention is to provide a kind of tilapia fish paste feed protein and processing method thereof, aiming at the current tilapia meal processing by-product fish paste with high feeding value, large discharge, easy to be corrupted and deteriorated, unable to keep fresh and stored, resulting in waste of resources and Environmental pollution, the current utilization of technology requires large investment, high production costs, and immature technology. The protein content and nutritional value of conventional fermented soybean meal cannot reach the level of fish meal. A kind of solid-state fermentation of fish paste absorbed by plant protein is provided to process it into high-quality feed. The protein method realizes the low-cost and large-scale fresh-keeping storage of fresh tilapia raw materials, and at the same time enables the beneficial fermentation of plant proteins, and the obtained fermented feed protein is more comprehensive and balanced in nutrition, so that the raw materials of tilapia pulp can be turned from waste to treasure. Do more harm than good

Embodiment 1

[0025] For every 1000Kg single plant feed protein or mixture, add fish paste 850Kg, molasses 8-10Kg, pineapple peel juice 30-70Kg, magnesium sulfate 300g, potassium phosphate 500g, ammonium sulfate 4500g, Bacillus subtilis 6kg, feed yeast 4 kg, 7 kg of Lactobacillus delbrueckii, when adding a large amount of pineapple peel juice, reduce the amount of molasses, stir and mix evenly, and ferment in the fermentation tank for 72 hours. During the first 40 hours of fermentation, if the temperature in the center of the pile exceeds 45°C It is necessary to take cooling measures such as stirring, and carry out drying, crushing, inspection, and packaging after the fermentation is completed.

Embodiment 2

[0027]For every 1000Kg single plant feed protein or mixture, add fish paste 850Kg, molasses 8-10Kg, pineapple peel juice 30-70Kg, magnesium sulfate 300g, potassium phosphate 500g, ammonium sulfate 4500g, Bacillus natto 7kg, feed yeast 5 kg, 8 kg of Streptococcus thermophilus, stir and mix evenly, and ferment in the fermentation tank for 72 hours. During the first 40 hours of fermentation, if the central temperature of the pile exceeds 45°C, cooling measures such as turning over should be taken. After the fermentation is completed, carry out Drying, crushing, inspection, packaging.

Embodiment 3

[0029] For every 1000Kg single plant feed protein or mixture, add fish paste 850Kg, molasses 8-10Kg, pineapple peel juice 30-70Kg, magnesium sulfate 300g, potassium phosphate 500g, ammonium sulfate 4500g, Bacillus subtilis 8kg, Tropical Candida 6 kg of yeast and 9 kg of Lactobacillus delbrueckii. When adding a large amount of pineapple peel juice, the amount of molasses added should be reduced appropriately, stirred and mixed evenly, and fermented in the fermentation tank for 72 hours. During the first 40 hours of fermentation, if the temperature in the center of the pile exceeds At 45°C, cooling measures such as stirring are required, and after fermentation is completed, drying, crushing, inspection, packaging, and finished products are carried out.

Abstract

A tilapia pulp feed protein and a processing method thereof, using peanut meal, rapeseed meal, cottonseed meal or a mixture to absorb tilapia pulp, adding bacterial strains for solid-state fermentation, drying and pulverizing to make fish paste feed Protein is used as protein raw material for feed industry and aquaculture industry. The method of the invention has the advantages of simple process, less investment in equipment, low cost, strong aroma of fish paste feed protein, good food attractant, high protein content, high small peptide content, easy digestion and absorption, and can reduce anti-nutritional factors in rapeseed meal and cottonseed meal , rich in probiotics, plays a positive role in increasing weight gain and feed conversion rate, enhancing the immune function of the body, and improving production performance. It can greatly replace fish meal in livestock and poultry feed, significantly reduce feed cost, and turn fish paste into waste It is a treasure, which is conducive to environmental protection and energy saving.

Description

technical field [0001] The invention relates to a tilapia pulp feed protein and a processing method thereof Background technique [0002] Fishmeal is an excellent protein feed and a strategic resource for the feed industry and aquaculture. The output of tilapia in my country ranks first in the world, and the main producing areas are Guangdong, Guizhou and Qiong. At present, tilapia is mainly processed into frozen fish fillets for export, and the processed leftover fish heads, fish steaks and viscera account for about 40-50% of the whole fish weight. More than %, tilapia leftovers contain a large amount of protein, fat, minerals and other substances, and have high utilization value. At present, the utilization of processing leftovers is mainly wet processing of fishmeal. For every ton of fishmeal produced, 3 to 3.5 tons of fish paste can be produced. The fish paste produced by fishmeal processing is usually 70% to 80% of the weight of the raw fish, of which the solid content ...
