The invention provides a preparation method of vacuum freeze
dried fruit and vegetable fruit granules through
probiotic fermentation. Fruit granules are stuffed and hardened, then the hardened fruit granules and fermenting mediums are fermented, probiotics are inoculated for
fermentation, and a vacuum
freeze drying technique is combined, so that the vacuum freeze
dried fruit and vegetable fruit granules through
probiotic fermentation are produced. Fermented
fruits and vegetables have complete
nutrition functions, during fermentation of
fruits and vegetables, probiotics can produce vitamins including B1, B2 and B6, as well as
vitamin K and the like, in addition,
lactic acid produced by the probiotics in the fermentation course also benefits absorption of
calcium, ferrum and
potassium by human bodies, and the fruits and the vegetables contain
nutrient components and
nutrient value richer than those of general
fruits and vegetables. The fermented fruit and vegetable fruit granules prepared by the method provide original nutrients of the fruits and the vegetables for human bodies, and the
nutrient value of the fruits and the vegetables can also be maximized. The fermented fruit and vegetable fruit granules are freeze-dried, the original thermal sensitivity components of products can be sufficiently guaranteed, color, scent, shape and activity of probiotics of the fruits and the vegetables can also be guaranteed, the quality guarantee period can be prolonged, and the fermented fruit and vegetable fruit granules are convenient to eat, transport and stored for a long term.
