Embodiment 1

[0011] A method for improving the utilization rate of chicken liver powder, comprising the following steps:

[0012] Take 5kg of chicken liver, chop it up, add 20L of water to homogenate it, and keep it warm at 35°C for 8 hours to make it autolyze. After reaching the specified time, adjust the pH value to 6.5, and then use a refrigerated centrifuge to centrifuge at 10°C and 9000 rpm to obtain 20 L of supernatant with a catalase activity of 28,000 U / ml and 5 kg of residue. The supernatant was concentrated by ultrafiltration with a hollow fiber ultrafiltration membrane with a cut-off molecular weight of 20kDa to obtain 11L of ultrafiltration concentrate with a catalase activity of 50,000U / ml, and 9L of ultrafiltration permeate; The roll-type nanofiltration membrane with a cut-off molecular weight of 150 was concentrated to obtain 0.4L of nanofiltration concentrate and 8.5L of nanofiltration permeate; the nanofiltration concentrate was combined with the residue, and the pH value ...

Embodiment 3

[0019] A method for improving the utilization rate of chicken liver powder, comprising the following steps:

[0020] Take 5kg of chicken liver, chop it up, add 20L of water to homogenate it, and keep it warm at 35°C for 8 hours to make it autolyze. After reaching the specified time, adjust the pH value to 6.5, and then use a refrigerated centrifuge to centrifuge at 10°C and 9000 rpm to obtain 20 L of supernatant with a catalase activity of 28,000 U / ml and 5 kg of residue.

Abstract

The invention relates to a method for improving the utilization rate of chicken liver powder. The method includes the steps that a chicken liver raw material is sheared into segments, the sheared chicken liver raw material is put in clean water, squeezed and rinsed to remove impurities and feces, then the chicken liver material is put into an enzymatic hydrolysis pot, water is added, heating is conducted, an animal protease and a flavor enzyme are added for enzymatic hydrolysis, the enzymes are inactivated, an organic acid is added to adjust the pH value, the obtained reactants are separated and concentrated, a flavoring agent is added to eliminate bitterness produced during enzymatic hydrolysis, an antioxidant is added to prevent fat oxidation, then steam cooking for sterilization is conducted, and finally sealed packaging is conducted. The method has a simple production process, prepared chicken liver peptides can be used as food for pet dogs and cats, and a large number of chicken liver produced by chicken slaughtering can be effectively utilized by the method to promote environmental protection.

Description

technical field [0001] The invention belongs to the technical field of feed raw material processing, and in particular relates to a method for improving the utilization rate of chicken liver powder. Background technique [0002] Chicken slaughtering and processing produce a large amount of chicken livers, which are mainly used as bait and fertilizer for fish, soft-shelled turtles, turtles, etc., or discarded, except for a small amount that is used by humans for cooking. It not only causes a waste of resources, pollutes the environment, but also spreads diseases. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a method for improving the utilization rate of chicken liver powder, which can effectively improve the utilization rate of chicken liver powder. [0004] The technical solution of the present invention is: a method for improving the utilization rate of chicken liver powder, comprising the following ste...
