Method for preparing antibiotic substituent for feed by probiotic asynchronous fermentation of Chinese herbal medicine

Abstract

The invention discloses a method for preparing antibiotic substituent for feed by probiotic asynchronous fermentation of Chinese herbal medicine, belonging to the field of food nutrition and the technical fields of microorganisms and feed. The method comprises the following steps: extracting Chinese herbal medicine by adopting asynchronous fermentation and enzymolysis technologies, namely adding water and nutritive salt in proportion to prepare a Chinese herbal medicine fermentation liquid after a plurality of Chinese herbal medicines are subjected to impurity removal and super-micro smashing; firstly inoculating Aspergillus niger for aerobic fermentation, thus cellulose and pectinase are prepared; and then inoculating enterococcus faecium and lactobacillus plantarum for anaerobic fermentation; and then carrying out enzymolysis on damage cell walls, and dissolving out active substances of saponin, alkaloid, phytosterol, enzymic preparations, organic acid and the like. A plate-and-frame filter press is adopted to filter the fermentation liquid, the filtration liquid is directly subjected to low-temperature spray drying to prepare antibiotic substituent powder A; a filtration cake is dried by adopting a roller drier to prepare antibiotic substituent powder B, and the power A and the powder B are mixed and formulated in proportion to replace fermented enzymolysis Chinese herbal medicine extracts of antibiotic for feed.

Description

technical field [0001] The invention belongs to the technical field of food nutrition, microbes and feed, and specifically relates to the asynchronous fermentation of Aspergillus niger and lactic acid bacteria to prepare Chinese herbal medicines such as camellia seed cake (meal) powder, ulmoides ulmoides leaves, astragalus, hawthorn, pine needle powder, epimedium and licorice, which can replace feed Fermentation and enzymatic hydrolysis of antibiotic herbal extracts. Background technique [0002] In recent years, food safety incidents have occurred frequently, and the hazards of antibiotics have attracted much attention: first, antibiotics are likely to remain in livestock and poultry products such as meat, eggs, and milk, endangering human health; Increased drug resistance. Therefore, some countries have banned its use. In 1974, the European Community prohibited the use of penicillin and tetracycline in feed, and in 1998, the use of spiramycin, bacitracin zinc, virginiamy...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: it is intended to overcome the research or products of the few Chinese herbal medicines extracted by fermentation for feeding on the above-mentioned market that are all single aerobic fermentation or anaerobic fermentation, and the fermentation products or researches of Chinese herbal medicines are also mostly single However, due to the lack of scientific formulas and the lack of separate drying of medicinal residues and medicinal liquids, it is planned to use asynchronous fermentation and enzymatic hydrolysis technology to extract Chinese herbal medicines, that is, to remove impurities and ultrafinely pulverize several kinds of Chinese herbal medicines for feeding, and then add water and nutrient salts in proportion to make them. To form a Chinese herbal medicine fermentation liquid, first insert Aspergillus niger for aerobic fermentation to produce cellulase and pectinase, then insert Enterococcus lactis and Lactobacillus plantarum for anaerobic fermentation, and then enzymatically hydrolyze the damaged cell wall to dissolve saponins and alkaloids , sterol organic acids and other active substances
