The invention belongs to the field of
food processing and particularly discloses fermented black
garlic powder and a preparation method thereof. The method comprises the following steps: pulping minced garlic, adding water, the weight of which is 25 times that of the minced garlic, to prepare garlic juice, heating, cooling through standing, adding a composite
lactobacillus fermentation agent, the weight of which is 3.5%-5% of the garlic juice, and carrying out sealed
fermentation at the pH of 5.9-6.3 and the temperature of 32-35 DEG C for 16-18 hours until the terminal pH of
fermentation liquor is 3.7-4.1; heating to the temperature of 100 DEG C, boiling for 30 minutes, then, adjusting the temperature to be 88-96 DEG C, performing fermentation by standing naturally for 36-42 hours, then, filtrating, carrying out high-speed
centrifugation, carrying out film-
evaporation concentration,
drying, crushing and sifting, thereby preparing the fermented black
garlic powder. According to the fermented black
garlic powder, a technical process of combining
probiotic biological fermentation and natural fermentation is adopted, so that the nutritive value of the product can be increased effectively,
bad tastes of the product are reduced, the
flavor is unique, and the mouth feel of the product is improved. The preparation method is simple in preparation process and has a good fermentation effect.
