Abstract

The invention relates to fermented milk containing fruit and vegetable particles and a preparation method thereof. The fermented milk containing fruit and vegetable granules in the present invention contains fruit and vegetable granules with fresh taste, flavor and texture, and preferably retains the original nutrition and active ingredients of the fruits and vegetables. The method for preparing fermented milk containing fruit and vegetable granules in the present invention adopts ultra-high pressure to pre-treat the raw milk and then ferments it, which not only effectively sterilizes but also achieves a certain homogeneous effect, and the fermented product has better viscosity and gelatinity , it is better to ensure the dispersion of fruit and vegetable particles, and there will be no sinking and aggregation during the shelf life. The fermented milk containing fruit and vegetable particles of the present invention can be placed at low temperature for 35 days, and the microorganisms of the product within the shelf life meet the national standard.

Description

technical field [0001] The invention relates to fermented milk containing fruit and vegetable particles and a preparation method thereof. Background technique [0002] Fruit yogurt refers to the milky product made by adding raw materials such as pulp, fruit flavor or jam before or after milk-based fermentation. The finished product must contain a large number of corresponding live bacteria. For yogurt manufacturers, developing fruit and vegetable extension products based on original flavor products can provide consumers with more choices and increase product market share. With the improvement of people's quality of life, people began to pay more and more attention to safety and health issues. Fruit yogurt, as a popular health product, has a growing demand for it. Usually, fruit and vegetable yogurt is made from fresh fruits and vegetables, and is made through processes such as washing, peeling, cutting, sugaring, acid adjustment, and high-temperature cooking, among which th...
