The invention discloses fermented wolfberry jam and a preparation method thereof. The preparation method for the fermented wolfberry jam comprises the following steps that (1) the edible part of wolfberry
pomace is rehydrated and ground so as to obtain fruit pulp, a compound
enzyme is added for enzymolysis, and refining treatment is carried out through a
colloid mill again; (2)
fresh milk or milkpowder reconstituted milk and the fruit pulp are mixed according to a certain ratio, and high-temperature sterilization is carried out so as to obtain mixed
fermentation liquor; and (3) a milk and fruit pulp
mixed solution is inoculated with a propagated strain for
fermentation so as to obtain the wolfberry jam. According to the fermented wolfberry jam and the preparation method thereof, a plurality of composite
bacteria are adopted for
fermentation, the prepared wolfberry jam is sour, sweet, palatable, smooth in taste, mellow and strong,
lutein and
carotenoid contained in the wolfberry pomacehave the oxidation resisting, eyesight improving and
eye protecting effects, amino acids, vitamins, mineral elements and soluble dietary fibers generated after compound strain fermentation can be more conveniently absorbed by human bodies, and the good
health improvement effect on digestive tracts is achieved.
