Embodiment 1

[0032] Prepare 20 kg of fresh beef bones, 60 kg of fresh leather, and 20 kg of beef.

[0033] Saw the fresh beef bone with a chainsaw into small pieces of 3×3cm, remove the grease and wash it with clean water, then put it into an autoclave, add 20 kg of water to cook, the steam pressure is 1.5kg, and the cooking time is 2 hours until the oil floats and the soup is clear , the index of bone crisp, separate the glue liquid wherein for subsequent use, contain albumen 2.4 (calculate by every hundred kilograms of fresh bovine bones containing albumen 12 kilograms) in the glue liquid.

[0034] After removing impurities from the fresh hide, soak it in lime water to degrease the collagen structure in the hide. Neutralize with hydrochloric acid after soaking. Then clean, put into autoclave after cleaning, add 60 kilograms of water to cook, steam pressure 1.5kg, cooking time 2h, separate hide glue for later use, contain protein 12.6 kilograms in the hide glue liquid (according to every...

Embodiment 2

[0039] Prepare 50 kg of fresh beef bones, 20 kg of fresh leather, and 30 kg of beef.

[0040] Saw the fresh beef bones into small pieces of 8×8cm with an electric saw, remove the grease and wash them with water, then put them into an autoclave, add 75 kg of water to cook, the steam pressure is 2kg, and the cooking time is 3 hours until the oil floats, the soup is clear, The index of bone crisp, the glue solution wherein is separated for subsequent use, contains 6 kilograms of protein in the glue solution (according to every 100 kilograms of fresh beef bones contains 12 kilograms of protein calculations).

[0041] After removing impurities from the fresh hide, soak it in lime water to degrease the collagen structure in the hide. Neutralize with hydrochloric acid after soaking. Then clean, put into autoclave after cleaning, add 30 kilograms of water to cook, steam pressure 2kg, cooking time 3h, separate hide glue for subsequent use, contain protein 4.2 kilograms in the hide glu...

Embodiment 3

[0046] Prepare 60 kg of fresh beef bones, 30 kg of fresh leather and 10 kg of beef.

[0047] Saw the fresh beef bone with a chainsaw into small pieces of 10×10cm, remove the grease and wash it with water, then put it into an autoclave, add 120 kg of water to cook, steam pressure 4kg, cook for 5 hours until the oil floats and the soup is clear , the index of bone crisp, separate the glue solution wherein for subsequent use, contain 7.2 kilograms of protein in the glue solution (calculate by every hundred kilograms of fresh beef bones containing 12 kilograms of protein).

[0048] After removing impurities from the fresh hide, soak it in lime water to degrease the collagen structure in the hide. Neutralize with hydrochloric acid after soaking. Then clean, put into autoclave after cleaning, add 60 kilograms of water to cook, steam pressure 4kg, cooking time 5h, separate hide glue for subsequent use, contain protein 6.3 kilograms in the hide glue solution (according to every hundr...

Abstract

The present invention provides I-type protein small peptide and its preparation process. The I-type protein small peptide has protein as the main component in 90 % or over, and protein component with molecular weight greater than 2500 Da accounting for 90 % or over of the protein. The present invention adopts biological emzymolysis process, which is reasonable, simple, feasible, high in efficiency, low in cost and suitable for industrial production. The product is produced with ox bone, hide, beef and other material, has rich protein and comprehensive nutritious components, and is suitable for people with poor digestion function to absorb protein and used as food additive to increase the protein content in food.

Description

technical field [0001] The invention relates to the field of biological products, in particular to a small type I protein peptide and a preparation process thereof. Background technique [0002] Protein is the first of the six elements that human beings depend on for survival, and is the main component of human cells. However, the molecular weight of protein is relatively large, usually between tens of thousands and hundreds of thousands. It must be digested by the human digestive system and turned into small molecules or amino acids before it can be absorbed by the human body. Infants and young children with immature digestive function, the elderly with impaired digestive function, and the infirm have certain difficulties in protein absorption. At present, there are no small protein peptides suitable for different groups of people to absorb and the preparation process for obtaining such small protein peptides that are easy to absorb and comprehensive in nutrition and suita...
