Description

Chinese herbal medicine composition for promoting growth of probiotics and application thereof
Technical Field
The invention belongs to the technical field of biology, and particularly relates to a Chinese herbal medicine composition for promoting growth of probiotics and application thereof.
Background
The probiotics change the efficacy of the Chinese herbal medicines or increase the synergistic effect by influencing the metabolism, transformation, absorption and other effects of the effective components of the Chinese herbal medicines. After microbial fermentation, active macromolecular substances in the Chinese herbal medicine are converted into small molecular substances which can be directly absorbed by animal intestinal tracts, and the small molecular substances are fully metabolized in animal bodies, so that medicine residues are avoided. The prebiotics produced by the Chinese herbal medicines after fermentation promote the propagation of microorganisms, and the microorganisms can promote the absorption and utilization of the Chinese herbal medicines. Meanwhile, the prebiotics can promote the growth of beneficial bacteria in the intestinal tract, increase the quantity of the beneficial bacteria and play a role in keeping the health of the intestinal tract. The three components complement each other and cooperate to better play the role of regulating immunity. The combination of probiotics, prebiotics and traditional Chinese medicines is an innovation point of functional food and traditional Chinese medicine research and development, and is also a new idea of traditional Chinese medicine modernization research.
There are many probiotics, prebiotic beverages and probiotic fermented traditional Chinese medicine products on the market at present, for example, gu Jinsong [1] et al patent describes a probiotic composition and application thereof, a probiotic product and a preparation method thereof, and the combined action of probiotics and polysaccharide is realized. However, there are relatively few products that utilize probiotics to ferment traditional Chinese medicine and prebiotics to make solid beverages.
Most of the existing probiotic products have improved taste by adding additives or sweeteners to the probiotic, for example Tang Zhenxing [2] et al describe a product in which the probiotic is embedded with sodium alginate, which has the disadvantage that there are many unknown factors for the long-term health effects of the additives; secondly, the activity of probiotics cannot be guaranteed, and the activity of probiotics is difficult to fully exert.
[1] Gu Jinsong, Qi Cuihua, zhangyu, etc. composition prepared by fermenting Chinese medicinal preparation with probiotics, and its preparation method and application are CN201210527023.9[ P ]. CN102934809A.
[2] Tang Zhenxing, xu Zheng, liu Ying, et cetera, a probiotic preparation and a method for preparing the same are disclosed in CN202210204681.8[ P ].2022.
