Benefits of technology

This new type of food called Fermentated Soymilage (FSO) was created during World War II for use as an ingredient or bread improving nutritional value while reducing harmful substances released from animal waste. FS0A describes different ways to make it easier than previous methods such as adding yeast strains directly onto raw materials like rice grain without losing their original taste attributes. These techniques help keep them alive longer even when they become contaminating with other microorganisms found on human skin.

Problems solved by technology

This patented technical issue addressed by this patents relates to finding new ways to improve the production of ferric acid-rich foods made through yeast culture processes without compromising their taste qualities such as flavor stability during storage.

preparation example Construction

[0028] The preparation process of the novel fermented soybean meal provided by the embodiment of the present invention mainly includes the following steps: preparing the seed solution of the bacteria, preparing the bacteria solution after expanding the culture, mixing the bacteria solution and the soybean meal and fermenting.

[0029] The strains used for preparing the strain seed solution include Hansenula anomalies, Bacillus subtilis and Lactobacillus acidophilus. In the embodiment of the present invention, Hansenula anomalius is used instead of the commonly used Saccharomyces cerevisiae for fermentation to produce esters and produce aroma, which is thicker and thicker than Saccharomyces cerevisiae fermentation, thereby improving the food-attractiveness of the feed. In addition, the above strains contain not only Hansenula anomaly and Bacillus subtilis which ferment aerobically, but also Lactobacillus acidophilus which ferment anaerobically. It is beneficial to improve the n...

Embodiment 1

[0062] Inoculate Hansenula abnormalis slant in YPD liquid medium, culture at 30°C and 200r / min for 20 hours, divide into shake flasks, and prepare 1.8L Hansenula abnormalis seed solution. Bacillus subtilis slant was inoculated in LB liquid medium, cultured at 37°C and 200r / min for 20h, divided into shake flasks, and 1.8L Bacillus subtilis seed solution was prepared. Lactobacillus acidophilus slant was inoculated in MRS liquid medium and cultured statically for 48 hours to prepare 1.8L Lactobacillus acidophilus seed solution.

[0063] The seed liquid of Hansenula anomaly, Bacillus subtilis and Lactobacillus acidophilus were respectively inoculated into three different 3-ton fermenters according to the inoculum amount of 0.5vt‰, and the loading amount was 60vt%. Among them, the Hansenula anomaly seed liquid and the Bacillus subtilis seed liquid were cultured for 15 hours, and the seed liquid of Lactobacillus acidophilus was cultured for 24 hours. The number of live bacteria in ...

Embodiment 2

[0072] Inoculate Hansenula abnormalis slant in YPD liquid medium, culture at 30°C and 200r / min for 24 hours, divide into shake flasks, and prepare 1.8L Hansenula abnormalis seed solution. Bacillus subtilis slant was inoculated in LB liquid medium, cultured at 37°C and 200r / min for 24 hours, divided into shake flasks, and 1.8L Bacillus subtilis seed solution was prepared. Lactobacillus acidophilus slant was inoculated in MRS liquid medium and cultured statically for 48 hours to prepare 1.8L Lactobacillus acidophilus seed solution.

[0073] The seed liquid of Hansenula anomalius, Bacillus subtilis and Lactobacillus acidophilus were inoculated into three different 3-ton fermenters according to the inoculation amount of 1.5vt‰, and the loading amount was 60vt%. Among them, the Hansenula anomaly seed liquid and the Bacillus subtilis seed liquid were cultured for 18 hours, and the seed liquid of Lactobacillus acidophilus was cultured for 28 hours. The number of live bacteria in Han...

Abstract

The invention relates to novel fermented soybean meal as well as a preparation process and application thereof, belonging to the field of feedstuff. The preparation process of the novel fermented soybean meal comprises the following steps of preparing a strain seed solution, preparing a bacteria solution after spreading cultivation, mixing the bacteria solution with the soybean meal and fermenting. Strains comprise hansenula anomala, bacillus subtilis and lactobacillus acidophilus. Fermentation comprises a first fermentation stage and a second fermentation stage which are continuously performed, an hansenula anomala bacteria solution and a bacillus subtilis bacteria solution are inoculated to the soybean meal when the first fermentation stage is started, and a lactobacillus acidophilus bacteria solution is inoculated to a fermentation system of the first fermentation stage when the second fermentation stage is started. The preparation process is simple, the condition controllability isgood, the fermentation time is short, and the efficiency is high. In the obtained fermented soybean meal, the contents of small molecule peptide and organic acid are relatively high, the antigen degradation is good, the living bacterium quantity is high, and the soybean meal has good flavor and palatability. By applying the fermented soybean meal to prepare pig feed, the feed intake of pigs can be effectively improved, the daily gain is increased, and the feed conversion rate and diarrhea rate are reduced.
