Fermented feed protein as well as preparation method and application thereof

Abstract

The invention discloses a fermented feed protein as well as a preparation method and application thereof. The preparation method of the fermented feed protein disclosed by the invention utilizes a stepwise fermentation way which specifically comprises the following steps: fermenting moringa seed meal with aspergillus niger and rhizopus oryzae so as to have macromolecules, including cellulose, proteins and the like, degraded into small molecules; inoculating the fermented moringa seed meal with enterococcus faecium so as to allow direct use of small-molecule substances; and then, further fermenting the moringa seed meal so as to have fermentation efficiency improved, thereby more effectively increasing nutritional values of the moringa seed meal. Being subjected to the fermentation, the moringa seed meal is capable of producing sour and aromatic flavor; and moreover, the fermented moringa seed meal has significantly improved crude protein content, acid-soluble protein content, neutral protease activity and the like compared with moringa seed meal subjected to single-bacterium fermentation. Therefore, the fermented moringa seed meal is rich in probiotics, and becomes a high-quality feed protein.

Description

technical field

[0001] The invention belongs to the technical field of feed processing, and in particular relates to a fermented feed protein and its preparation method and application. Background technique

[0002] Feed protein is an important resource for aquatic products and livestock breeding. At present, all countries in the world have a great demand for feed protein, coupled with the increase in the price of traditional feed protein such as fish meal, looking for potential, high-quality feed protein is one of the important goals of the current aquaculture industry. Therefore, optimizing feed formula and reducing feed cost are important research issues in the aquaculture industry. Compared with traditional feed protein, fermented feed protein has the advantages of high digestibility and high feed-to-meat ratio. In recent years, there have been more and more researches on the production of new fermented feed protein from agricultural and animal husbandry waste such as s...
