Embodiment 1

[0024] (1) Use whey protein as raw material, add 5 times the weight of water, pass through a colloid mill, add papain to hydrolyze until the degree of hydrolysis of whey protein is 10%, keep at 80°C for 30 minutes to inactivate the enzyme, centrifuge at 6000g for 30 minutes, and use cut-off molecular weight Perform ultrafiltration on a 30kDa membrane to obtain permeate to obtain whey protein hydrolyzate;

[0025] (2) Enzymatic hydrolysis and concentration of whey protein to a solid content of 30% to obtain an enzymatic hydrolysis concentrate;

[0026] (3) Add 0.01% ethyl maltol by weight of the concentrated solution to the enzymolysis concentrated solution, and keep it warm at 100°C for 3 hours to obtain No. 1 piglet feed ingredient.

[0027]

Embodiment 2

[0029] (1) Use whey protein as raw material, add 10 times the weight of water, pass through a colloid mill, add trypsin to hydrolyze until the degree of hydrolysis of whey protein is 15%, keep at 90°C for 20 minutes to inactivate the enzyme, centrifuge at 7000g for 20 minutes, and use cut-off molecular weight Perform ultrafiltration on a 50kDa membrane to obtain permeate to obtain whey protein hydrolyzate;

[0030] (2) Enzymatic hydrolysis and concentration of whey protein to a solid content of 35% to obtain an enzymatic hydrolysis concentrate;

[0031] (3) Add 0.05% ethyl maltol by weight of the concentrated solution to the enzymolysis concentrated solution, and keep it warm at 110°C for 2 hours to obtain No. 2 piglet feed ingredient.

[0032]

Embodiment 3

[0034] (1) Use whey protein as raw material, add 15 times the weight of water, pass through a colloid mill, add compound protease (Protemex) to hydrolyze until the degree of hydrolysis of whey protein is 20%, keep at 95°C for 10 minutes to inactivate the enzyme, and centrifuge at 8000g for 15 minutes. Using a membrane with a cut-off molecular weight of 100kDa to perform ultrafiltration to obtain the permeate to obtain a whey protein enzymatic hydrolyzate;

[0035] (2) Enzymatic hydrolysis and concentration of whey protein to a solid content of 40% to obtain an enzymatic hydrolysis concentrate;

Abstract

The invention relates to a piglet forage ingredient and its preparation method and use. The preparation method comprises the following steps of carrying out controlled-enzymatic hydrolysis of lactalbumin to a hydrolysis degree of 15 to 20%, carrying out sterilization at a temperature of 80 to 95 DEG C for 10 to 30min, concentrating the sterilized enzymatic hydrolysis product into an enzymatic hydrolysis product concentrated solution having solid content of 30-40%, adding 0.1 to 0.3% of ethyl maltol into the enzymatic hydrolysis product concentrated solution, and carrying out heat preservation at a temperature of 100 to 120 DEG C for 1 to 3h to obtain the piglet forage ingredient. Through being used in weaned piglet forage, the piglet forage ingredient can obviously improve piglet forage attraction to a weaned piglet.

Description

technical field [0001] The invention relates to the preparation technology and application of piglet feed, in particular to the preparation method and application of piglet feed ingredients that can attract weaned piglets to eat. Background technique [0002] The feeding of weaned piglets is an important link in pig production. The transition from mainly consuming breast milk to solid feed during weaning and other weaning stresses lead to reduced feed intake and growth retardation in piglets. For weaned piglets, they have no experience of contacting solid feed, and their feeding experience is mainly obtained from eating breast milk. Therefore, how to make weaned piglets accept solid feed as soon as possible is the key to weaned piglet feeding. At present, a lot of research has been done on weaned piglet feed at home and abroad, mainly focusing on the following directions: (1) The production method or formula of functional piglet feed. For example, the patent on a compound f...
