Abstract

The invention discloses skim-flavor yogurt fermentation powder and a preparation method therefor. The method comprises the following steps: 1) remade milk blending: mixing dried skim milk, white granulated sugar, edible glucose, a yeast extract and water, and then, carrying out homogenization treatment, so as to obtain remade milk; 2) culture medium preparing: sterilizing the remade milk prepared in the step 1), then, carrying out cooling, and taking the sterilized remade milk as a culture medium; 3) inoculating: inoculating skim-flavor lactic acid bacteria with the culture medium prepared in the step 2); 4) fermenting: fermenting the inoculated culture medium obtained in the step 3) so as to form fermentation liquor; 5) blending: adding maltodextrin into the fermentation liquor prepared in the step 4), and carrying out stirring to thoroughly dissolve the maltodextrin, so as to prepare a uniform blended solution; and 6) spray drying: carrying out spray drying treatment on the blended solution prepared in the step 5), thereby obtaining the skim-flavor yogurt fermentation powder. The skim-flavor yogurt fermentation powder prepared by the method can be supplied to markets and is used for producing skim-flavor yogurt foods.

Description

technical field [0001] The invention relates to a defatted flavored yogurt fermented powder and a preparation method thereof. Background technique [0002] Skimmed flavored yogurt is a traditional fermented milk product, which contains a large amount of lactic acid bacteria, which can destroy the conditions for the survival of spoilage bacteria in the human body, enhance the digestive ability of the human gastrointestinal tract, and inhibit the growth and reproduction of harmful bacteria. It has rich nutritional value and Good health function. With the improvement of people's living standards and the popularity of health concepts, non-fat flavored yogurt is being loved by more and more people for its rich nutrition, easy digestion and absorption, low calorie, pleasant fragrance, sweet and sour taste. But the defatted flavored yoghurt also has the disadvantages of low temperature storage, carrying and long-distance transportation. At the same time, when food companies, merc...
