Hydrolysis fermentation protein and its preparation method

Abstract

The invention discloses a hydrolyzed fermentation protein and a preparation method thereof, pertaining to a protein feed and the preparation method thereof. Aiming at solving the problems of great loss, strong odor, high energy consumption, high cost and low output of the existing method for producing amino acid powder and the problems of easy moisture absorption and high content of ammonium salt of the existing amino acid powder, the invention provides the hydrolyzed fermentation protein that contains above 40 percent of protein, above 15 percent of amino acid and under 8 percent of ammonium salt according to weight percentage. The invention also provides a preparation method of the hydrolyzed fermentation protein. The method comprises the following steps: concentrating the water agent of hydrolyzed amino acids, absorbing the hydrolyzed amino acids by grinded plant, fermenting, baking, cooling and grinding. The preparation method has the advantages of low equipment investment, light odor, low energy consumption, high output and low cost in the preparation process; the product has low content of ammonium salt, does not absorb moisture and is beneficial to popularization and application.

Description

technical field

[0001] The invention relates to a hydrolyzed fermented protein feed and a preparation method thereof. Background technique

[0002] Hydrolyzing keratin protein to produce amino acids will produce a large amount of unextracted amino acid wastewater during the production process, which is likely to cause environmental pollution. To digest these amino acid waters, packaging, transportation, and sales costs are very high. Taking packaging as an example, one ton of amino acids for sale The packaging of water (for agricultural use, 100ml / bottle, 200ml / bottle, 500ml / bottle) costs 3,000-5,000 yuan, and the packaging of every 100,000 tons of amino acid water costs 300 million yuan, which is too high. Therefore, it is necessary to use these amino acid waters to produce compound amino acid powder in large quantities to reduce packaging and transportation costs. However, at present, compound amino acid powder is all produced by spraying, which consumes a lot of coal; De...

Examples

Embodiment 1

[0025] Using hair, pig hair, feather and other keratin protein as raw materials, hydrolyzed by HCl, NH 3 The process of neutralization prepares cystine, and the amino acid wastewater extracted from cystine is the hydrolyzed amino acid aqueous solution in this embodiment.

[0026] Hubei Xinxinyuan Bioengineering Co., Ltd. is a manufacturer of cystine. During the production process, it produces a large amount of unextracted amino acid wastewater containing 8wt% of nearly 100,000 tons per year. There are many similar manufacturers in China. How to economically and effectively Turning waste into treasure is exactly the problem to be solved by this patent.

[0027] The preparation method of the hydrolyzed fermented protein in the present invention is, the hydrolyzed amino acid aqueous solution (using conventional methods such as evaporation) is concentrated, and the degree of concentration is based on the amino acid weight in the hydrolyzed amino acid aqueous solution accounting fo...

Embodiment 2

[0031] The difference between this example and Example 1 is that the ammonium salt in the concentrated hydrolyzed amino acid solution is first separated by adding sodium hydroxide or lime, and then adsorbed by crushing plants. This separation process can reduce the ammonium salt in the amino acid water solution according to the need. In the specific operation, the removal amount of the ammonium salt can be controlled according to the different needs of producing high-end or low-end products.

Embodiment 3

[0033] The difference between this example and Example 2 is that after the crushed plants are used for adsorption, the concentrated hydrolyzed amino acid water is fermented together with the vegetable protein. During the fermentation process, part of the ammonium salt can be converted into bacterial protein, and the ammonium salt While making the product utilization rate higher.
