The invention discloses a medicinal and edible
probiotic composite preparation formula optimization segmented
fermentation method, and relates to the technical field of
fermentation engineering, and the method comprises the following steps: S1,
raw material pretreatment: selecting red
ginseng,
donkey-hide
gelatin and red rose according to a weight ratio of 3: 2: 1 to form a composite
raw material, crushing the red
ginseng and the red rose, sieving with a 80-mesh
sieve, dissolving the
donkey-hide
gelatin with
warm water, mixing with the crushed red
ginseng and red rose, and carrying out uniform mixing to obtain a mixed material; adding
sterile water until the ratio of the total
mass of the raw materials to the weight of the
sterile water is 1: 5, adjusting the initial pH value to 6.8-7.0, putting the raw materials into a
fermentation tank, sterilizing at 121 DEG C for 20 minutes, and cooling to
room temperature; by adopting a multi-temperature-zone dynamic segmented fermentation design, four dynamic temperature zones and matched stirring and inoculating parameters are accurately set by combining a
probiotic growth curve and a conversion rule of active ingredients in red ginseng,
donkey-hide
gelatin and red roses, so that the core contradiction between
probiotic proliferation and
active ingredient conversion in existing fixed temperature zone fermentation is effectively solved; good growth and
reproduction of probiotics are guaranteed, and full conversion of active ingredients such as
saponin and flavone in the raw materials is promoted.
