Problems solved by technology

At present, domestic feeding blood meal processing mainly adopts the traditional steaming method, the digestibility of the dried blood meal produced by this processing method is 30% to 50%, the bloody smell is heavy, the palatability is poor, and the utilization rate is low
In recent years, with the rapid development of bio-enzyme technology, there have been many reports on the method of enzymatically hydrolyzing blood meal by using proteases to improve its utilization rate, but the actual application effect is not satisfactory

Embodiment 1

[0018] Example 1, the enzymatic processing method of whole blood polypeptide protein powder using fresh blood of livestock and poultry as raw material.

[0019] (1) Steam the fresh blood or water-blood mixture collected from the livestock and poultry slaughterhouse, control the blood coagulation temperature to 80°C, and sterilize; dehydrate the coagulated blood containing 80% to 90% water by centrifuge , to reach a substrate concentration of 50% into the enzymolysis reaction tank;

[0020] (2) Add 3 ‰ of sodium bicarbonate by substrate weight to adjust the pH value to 7.5, and add 3 ‰ by substrate weight simultaneously by 1 part of weight of alkaline protease, 1 part of weight of aspergillus oryzae and 2 parts of weight of Mix the compound enzyme composed of trypsin, stir it well, keep it at 55°C for 6 hours, and carry out the enzymatic hydrolysis reaction;

[0021] (3) At the 7th hour, add the reducing agent sodium metabisulfite according to 5‰ of the weight of the substrate...

Embodiment 2

[0025] Example 2, the enzymatic processing method of whole blood polypeptide protein powder using dried blood clots of livestock and poultry as raw material.

[0026] (1) After removing impurities, the dried blood clots of livestock and poultry are pulverized, put into an enzymolysis tank, add water and stir and mix until the substrate concentration is 50%;

[0027] (2) Add 3‰ of compound enzyme and 3‰ of sodium bicarbonate according to the weight of the substrate to adjust the pH value to 7.5, after fully stirring, keep the temperature at 55°C for 6 hours, and carry out the enzymolysis reaction; the compound enzyme is prepared in parts by weight A mixed composition of 1 part of alkaline protease, 1 part of aspergillus oryzae and 2 parts of trypsin;

[0028] (3) Add 5‰ reducing agent sodium pyrosulfite according to the weight of the substrate in the 7th hour, leave it to stand after fully stirring, and carry out the reduction reaction;

[0029] (4) In the 8th hour, the temper...

Abstract

The invention discloses an enzymolysis processing method of whole blood polypeptide albumen powder. In the method, livestock and poultry blood serve as a raw material, proper primer density, effective albumen enzymolysis complex enzyme and reductant and enzymolysis reaction temperature are chosen to cause livestock and poultry blood to be performed with enzymolysis reaction, reduction reaction and low-temperature drying and smashing to obtain the whole blood polypeptide albumen powder. The enzymolysis processing method degrades large-molecular albumen hard to adsorb and utilize in the livestock and poultry blood into small-molecular albumen, polypeptide and free amino acid easy to digest and adsorb, and improves the palatability and the nutritional value of dried blood for feeding. The processing method has small investment, low cost, short reaction time and high production efficiency. The whole blood polypeptide albumen powder obtained by the processing method can lower feed formulation cost if added by 1-5% in animal diet, improve feed compensation, enhance daily gain andresistance to disease and obtain favourable economic benefit.

Description

technical field [0001] The invention relates to an enzymolysis processing method for producing whole blood polypeptide protein powder for feeding by using livestock and poultry blood as raw material. Background technique [0002] my country is rich in livestock and poultry blood resources. Every year, 570 million pigs, 35 million cattle, 2.6 billion sheep, and 9.8 billion poultry are slaughtered. The annual livestock and poultry blood resources exceed 350,000 tons. Livestock and poultry blood is rich in protein and is an important animal protein resource. In the feed industry, the utilization of livestock and poultry blood is mainly to process it into blood meal as animal protein supplement feed. At present, domestic feed blood meal processing mainly adopts the traditional steaming method. The digestibility of the dried blood meal produced by this processing method is 30% to 50%, and the bloody smell is heavy, the palatability is poor, and the utilization rate is low. In r...
