Problems solved by technology

[0006] In the prior art, a large amount of water is needed to prepare intestinal membrane protein powder by enzymatic hydrolysis of intestinal slag, and the substrate concentration is small, which is not conducive to environmental protection. The cost of drying is increased, and the amount of protease is large, the hydrolysis steps are complicated, and the hydrolysis time is long, so it is not suitable for large-scale industrial production

Embodiment 1

[0040] Weigh 1000 kg of intestinal residue after extracting heparin from pig intestinal mucosa, add 150 kg of water, and stir at 25° C. at a speed of 80 rpm for 40 minutes to obtain a mixture of intestinal residue and water. Add 5 kg of alkaline protease to the mixture of intestinal residue and water, raise the temperature to 40°C, add solid sodium hydroxide powder to adjust the pH to 9.0, mix well, and keep it warm at 40°C for 4 hours to obtain a hydrolyzate. The hydrolyzate is spray-dried to obtain intestinal membrane protein powder.

Embodiment 2

[0042] Weigh 1000 kg of intestinal residue after extracting heparin from pig intestinal mucosa, add 200 kg of water, and stir at 150 rpm for 20 minutes at 37° C. to obtain a mixture of intestinal residue and water. Add 0.5kg of alkaline protease to the mixture of intestinal residue and water, raise the temperature to 55°C, add solid sodium hydroxide powder to adjust the pH to 10.0, mix well, and keep it warm at 55°C for 2 hours to obtain a hydrolyzate. The hydrolyzate is spray-dried to obtain intestinal membrane protein powder.

Embodiment 3

[0044] Weigh 1000 kg of intestinal residue after extracting heparin from pig intestinal mucosa, add 250 kg of water, and stir at 100 rpm for 30 minutes at 40°C to obtain a mixture of intestinal residue and water. Add 10kg of alkaline protease to the mixture of intestinal residue and water, raise the temperature to 60°C, add solid sodium hydroxide powder to adjust the pH to 11.0, mix well, and keep it warm at 60°C for 1 hour to obtain a hydrolyzate. The hydrolyzate is spray-dried to obtain intestinal membrane protein powder.

Abstract

The invention provides a production and processing process of intestinal membrane albumen powder. By taking intestinal mucosa of a pig or intestinal residues with heparin extracted as a raw material, the process comprises the following steps: 1) after mixing water and the raw material in a weight ratio of (15-30) to 100, stirring for 30-60 minutes at 35-40 DEG C; 2) adding alkaline protease into the mixture of water and raw material in the step 1) in a weight ratio of (0.05-1):100, heating to 40-60 DEG C, adjusting the pH to 9.0-11.0, and preserving heat and hydrolyzing for 1-4 hours at 40-60 DEG C to obtain a hydrolysate; 3) spray drying or roller drying the hydrolysate to prepare the intestinal membrane albumen powder. The process of preparing the intestinal membrane albumen powder by using a small amount of water and alkaline protease under the alkaline condition has the characteristics of simple operation, short hydrolytic time, energy conservation and environmental protection, small use level of water and alkaline protease, low preparation cost and the like, and can satisfy the requirements on industrialized production on a large scale.

Description

technical field [0001] The invention belongs to the field of biochemical technology, and in particular relates to a production and processing technology for preparing intestinal membrane protein powder by hydrolyzing the by-product of the process of extracting heparin from pig small intestinal mucosa. Background technique [0002] Protein hydrolyzate is mainly a mixture of amino acids and peptides obtained by enzymatic, acid or alkaline hydrolysis of animal or plant proteins, generally called peptone. Protein hydrolyzate is rich in organic nitrogen compounds, and also contains some vitamins and sugars, which can be used as fermentation substrates, high-quality protein sources for humans or animals, etc. [0003] Pig intestinal mucosa or intestinal dregs contain 56.2% crude protein, and the content of various amino acids is similar to that of high-quality fish meal. Intestinal membrane protein powder is a new type of protein hydrolyzate produced from pig small intestine and ...
