The Research Progress of Tea Saponin in Oil-tea Cake by Microbial Degradation Method

Tea saponin is an important component in camellia cake. Tea saponin toxicity and palatability difference reduces the oil-tea cake as feed utilization, in order to make full use of the oil-tea cake, reduce the content of the tea saponin, become the most effective way to differential fertilizer utilization. In recent years, the method of microbial degradation of tea saponin got very good application, microbial fermentation, not only has a short fermentation time, mild process, small investment, simple process, no secondary pollution, etc, and it can greatly improve the palatability of oil-tea cake. This paper discusses the variety of bacteria, fungi, bacteria fermentation and mixed bacteria fermentation degradation research progress of tea saponin. aspergillus Niger and mixed strains in their respective optimal culture conditions, can for the degradation of tea saponin.
