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...
