Method for improving feeding nutritive value of sesame seed meal by combining enzymolysis method with fermentation method

Abstract

The invention discloses a new process for improving the nutritional value of sesame meal by using enzymatic hydrolysis and microbial fermentation. The process prepares high-value-added fermented sesame meal products with high protein content, rich in nutrients such as polypeptides, small peptides, amino acids, organic acids, and probiotics, and low in anti-nutritional factors such as phytic acid and tannins. Crude protein content of fermented sesame meal products ≥ 50%, acid soluble protein content ≥ 10%, hydrolysis degree ≥ 35%, organic acid content ≥ 5%, phytic acid content ≤ 0.1%, volatile basic nitrogen content ≤ 100mg / 100g, The feed utilization rate is improved, and the cost of breeding is reduced; the application of fermented sesame meal in aquatic feed increases the amount of fermented sesame meal in aquatic feed, and can partially replace the application of fish meal and soybean meal. In addition, the present invention adopts solid static fermentation, and does not need to be sterilized in the fermentation process, the production process is simple, the production cost is low, and the prospect of industrial production is broad.

Description

technical field [0001] The invention relates to a new process for improving the nutritional value of sesame meal for feeding by using an enzymatic hydrolysis method and a microbial fermentation method, and belongs to the field of feed processing. Background technique [0002] Protein raw materials are the foundation of the development of the feed industry. The shortage and high price of protein raw materials in my country have become one of the bottlenecks in the development of animal husbandry and aquaculture. At present, with the improvement of people's living standards and the emphasis on the quality of life, the demand for meat, eggs, milk, and aquatic products is increasing day by day. The production of grain and feed is facing severe challenges, and feed protein resources will become increasingly scarce. It is imminent to expand feed resources and develop unconventional feed. The important strategy to alleviate the contradiction is to improve the utilization rate of ...

Problems solved by technology

Although the above studies have certain effects on the removal of phytic acid, they all use aerobic bacteria for aerobic fermentation. Compared with anaerobic fermentation, aerobic fermentation will consume a lot of nutrient production capacity, and at the same time, intermediate metabolites will be completely oxidized and lost.

Anaerobic fermentation using anaerobic or facultative anaerobic microorganisms has been reported on soybean meal, rapeseed meal, etc., but there is no report on the use of biological fermentation method for phytic acid and tannin degradation of sesame meal
