The present application belongs to the technical field of eight-treasure fermented black bean, and particularly relates to a preparation method of germinated black bean
probiotic fermented eight-treasure fermented black bean. The preparation method of germinated black bean
probiotic fermented eight-treasure fermented black bean comprises the following steps: S1, main material preparation: using germinated black beans in the white-leaf stage,
steaming, cooling, and then obtaining
fermentation main material; S2, auxiliary material preparation; S3, segmented koji making: sequentially connecting the
fermentation main material into four kinds of bacterial agents for three-stage segmented koji making, and obtaining koji material; S4, product preparation: mixing the auxiliary material into the koji material, and then performing homogenization, sealing, post-
ripening, low-temperature sterilization, and aseptic filling to obtain the finished product. The present application uses the germinated black beans in the white-leaf stage as the main material, and uses the segmented koji making process of four kinds of bacterial agents, realizes deep degradation of anti-nutritional factors, efficient
hydrolysis of
protein, rich ester
aroma, and retention of high content of isoflavone
aglycone, and the product has mellow
flavor and strong functionality, the process is stable and controllable, and is suitable for industrial production.
