Beta-glucan-enriched fermented feed and preparation method thereof,

Abstract

The present invention discloses a beta-glucan-enriched fermented feed and a preparation method thereof. The beta-glucan-enriched fermented feed comprises the following steps: (1) after soybean molasses are fermented, the fermented soybean molasses with water content of 40-70 wt% are obtained; (2) plant fiber feed raw materials with protein content of less than 20% are prepared; and 300-1,000 kg ofthe fermented soybean molasses obtained in the step (1) are added into per ton of the feed raw materials; and the materials are mixed and stirred; and (3) the mixture fermenting, drying and crushingare conducted to obtain the dry fermented feed. The preparation method is a step-by-step-method solid open-type fermentation technology; the soybean molasses and high-fiber feed raw materials are applied for production; due to the fact that the high-concentration molasses with solid content of 30%-60% are used for the fermenting, beta-glucan content in the fermentation product is ensured; and thefinished product achieves the high beta-glucan content and greatly reduces the cost of applying the beta-glucan for animal breeding.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a fermented feed and a production method thereof. Background technique [0002] β-glucan is a polysaccharide composed of glucose units, most of which are combined by β-1,3, which can activate macrophages and neutrophils, increase the content of leukin, cytokinin and special antibodies, thereby enhancing body immunity. [0003] Soybean molasses is a by-product of the production of concentrated soybean protein. It is rich in various oligosaccharides such as sucrose, raffinose, and stachyose, and has high biological application value. Soybean molasses is added as a carbon source into high-fiber feed materials, and a large amount of β-glucan and its organic acids can be produced through microbial fermentation, which can improve immunity, regulate intestinal tract and promote growth of farmed animals. [0004] However, the current conventional fermented feed can only...

AI Technical Summary

Problems solved by technology

[0004] However, the current conventional fermented feed can only use low-concentration molasses as a carbon source, and the solid content of the molasses dilution is 5%-15%, that is, the water content is 85%-95%, because high concentrations will inhibit lactic acid, yeast, etc. Seed strain growth

However, adding low-concentration molasses to the fermentation system will eventually produce very limited β-glucan
