Abstract

The invention discloses a freeze-dried fruit yoghourt block and a preparation process thereof. The freeze-dried fruit yoghourt block comprises the following raw materials in parts by weight: 5-10 parts of yoghourt, 1-2 parts of saccharide, 1-2 parts of milk powder, 1-2 parts of whey powder, 1-2 parts of citric acid, 0.1-0.5 part of starch and 0.1-0.2 part of pectin. According to the invention, fruit grains are mixed with the yoghourt, and processing procedures of quick freezing and freeze drying are carried out, so that the water content in the freeze-dried fruit yoghourt block is reduced, therespiration rate of microorganisms in raw materials is reduced, and the shelf life of the raw materials is prolonged; the quick drying procedure enables the water loss rate in the raw materials to reach 80%-90%, so that the loss rate of nutrient components is reduced; the added water is filtered and is subjected to boiling treatment, and the sterilization effect is high; and meanwhile, macromolecular saccharides in fruits are converted into small molecular substances which can be absorbed more easily, so that the absorption rate of the nutrient components of human bodies is increased.

Description

technical field [0001] The invention relates to the technical field of fruit yoghurt block preparation, in particular to a freeze-dried fruit yoghurt block and a preparation process thereof. Background technique [0002] With the improvement of living standards, people pay more and more attention to nutrition and health care. Fruit and yogurt have become a good natural partner and one of people's favorite delicacies. However, due to the influence of microorganisms, fresh fruit yogurt has a shelf life of only a few hours. It is suitable for on-site production and ready-to-eat. Fruit yogurt currently on the market uses canned fruit or jam, and preservatives are added to the canned fruit and jam to prolong the shelf life, which affects people's consumption and is also harmful to the human body. [0003] After searching, the Chinese patent application publication number CN102450322A discloses a freeze-dried fruit yoghurt, which is composed of freeze-dried fruit and yoghurt base...
