Production process of composite probiotics

Abstract

The invention discloses a production process of composite probiotics. The process comprises the following specific steps of: 1, breeding, namely (1) preparing a culture solution, and heating, dissolving and saccharifying the culture solution to obtain a saccharified solution; (2) sterilizing the saccharified solution at a high temperature, and cooling the sterilized saccharified solution to obtain a breeding culture medium; and (3) inoculating strains of lactic acid bacteria, bifidobacterium, bacillus subtilis and candida utilis into the breeding culture medium for culturing, thus obtaining four mature bacterium solutions; 2, fermentation, namely (1) mixing and sterilizing bean pulp and bran, thus obtaining a solid material; (2) respectively adding the four mature bacterium solutions into a diluent, thus obtaining four diluted bacterium solutions after diluting; and (3) respectively inoculating strains of the four diluted bacterium solutions into the solid material for fermentation, thus obtaining four fermented materials; and 3, drying and packaging, namely (1) mixing the four fermented materials and drying the mixed materials for the first time; (2) drying the mixed materials for the second time; (3) drying the mixed materials for the third time; and (4) crushing, outputting and packaging the dried materials to obtain the composite probiotics. The process can realize large-scale and continuous production and is suitable for industrial production.

Description

Technical field [0001] The invention belongs to the field of biotechnology, and particularly relates to a production process of composite probiotics. Background technique [0002] With the rapid development of the current feed industry, various feed additives are also showing a diversified trend. Due to the gradual emergence of the various disadvantages of antibiotics, compound probiotics can adjust the structure of animal intestinal flora, improve the activity of digestive enzymes in animals, and improve Animal production performance and the excellent characteristics of improving animal immunity have gradually become indispensable feed additives in the animal husbandry industry. [0003] At present, the research, development and application of composite probiotics in my country is still in its infancy. The production methods of most composite probiotics are simply the expansion of laboratory preparation methods, which are not suitable for large-scale and continuous industrial prod...

Problems solved by technology

[0003] At present, the research, development and application of compound probiotics in my country is still in its infancy, and the production methods of most compound probiotics are only simple expansion of laboratory preparation methods, which are not suitable for large-scale and continuous industrial production, and are not suitable for temperature , The control of fermentation time is not strict enough, resulting in the problems of short shelf life, evolution of probiotic population structure, and low biological activity
