Fermentation full-fat bean feed and preparation method thereof

Abstract

The invention discloses a fermented full-fat soybean feed and a production method thereof. The production method comprises the following steps: 1) water supplementation and bacterial inoculation; 2) fermentation starter preparation under ventilation condition; 3) granulation under anaerobic condition; 4) fermentation under heat insulation; and 5) air-drying and pulverization. The fermented full-fat soybean feed contains more than or equal to 40% of crude protein, more than or equal to 16.5% of crude fat, less than or equal to 6.0% of crude fiber, less than or equal to 6.0% of crude ash, more than or equal to 2.4% of lysine, more than or equal to 6.0% of methionine, and less than or equal to 12% of water. The fermentation production process reduces the loss of lipids and fats of the fermented full-fat soybean feed, increases the nutritional indexes, increases the utilization rate of soybean, improves the efficiency of feed production, and reduces the cost of feed production.

Description

Technical field [0001] The invention relates to a full-fat soybean feed and a production method thereof, in particular to a fermented full-fat soybean feed and a production method thereof. Background technique [0002] Soybean is the main agricultural product in my country, with an annual output of 12 million tons. Generally, raw soybeans contain 32% to 40% of crude protein, mostly water-soluble protein, good amino acid composition, rich in essential amino acids such as lysine and histidine, crude fat accounts for 17% to 20%, and is an unsaturated essential fatty acid , of which linolenic acid accounts for 55%, and has high utilization value. In addition, raw soybeans are low in carbohydrates, rich in B vitamins, and low in vitamin A and vitamin D. For the above reasons, soybean is a very high-quality feed resource. [0003] However, because raw soybeans contain sugars (commonly known as flatulence factors) that hinder digestion, excessive intake of food is easy to fermen...

Problems solved by technology

[0006] In addition, the current method of using fermentation technology to produce full-fat soybeans is available in the seasoning food industry. If it is directly applied to the field of feed production, the production efficiency will be low due to large investment in equipment, low production efficiency, and inability to continue production. low cost problem
