The invention belongs to the technical field of
biotechnology, and discloses a
kefir whey and tea
polyphenol composition as well as a preparation method and application thereof. The method comprises the following operation steps: preparing a reduced milk solution from
whole milk powder by using
sterile water, sterilizing in a water bath, naturally cooling, adding
kefir grains into the sterilized reduced milk under sterile operation, fermenting for 7-45 days at the constant temperature of 15-30 DEG C under a sealed condition, centrifuging, and filtering to obtain a
kefir whey primary extracting solution; the preparation method comprises the following steps: preparing a
Kefir whey working solution, carrying out reduced pressure
evaporation and concentration to obtain a
Kefir whey working solution, adding tea
polyphenol into the
Kefir whey working solution to prepare a solution with the
mass percentage concentration of tea
polyphenol being 0.05-0.5%, carrying out split charging, and carrying out water bath sterilization to obtain the Kefir whey and tea polyphenol composition. The composition has a very good effect of treating the
inflammatory bowel disease, and the kefir whey and the tea polyphenol are derived from edible raw materials, so that the product is edible, high in safety, simple in production process and relatively low in cost.
