Abstract

The invention discloses a preparation method of fruit and vegetable granules for being added into normal-temperature yogurt. The preparation method includes the steps: cutting at least one of the fruits or vegetables into small blocks, and adding 30-40% of white granulated sugar, 0.2-0.3% of thickening agents, 0-1% of edible essence and 0.5-2% of acidity regulators to obtain mixture in weight percent; stewing the mixture, sterilizing the stewed mixture, and filling tanks with the mixture to obtain the fruit and vegetable granules. The content of net fruit granules in the fruit and vegetable granules is 50-60%, the viscosity of the fruit and vegetable granules is 4-8cm / min, the content of total protein and fat is 0wt%, and the content of carbon water is 30-40wt%. The state of the fruit andvegetable granules is good in the placing process of 6-9 months at normal temperature, water separation out and laying are omitted, product uniformity is high, fruit and vegetable flavor is effectively released, the viscosity and the liquidity are moderate, and the fruit and vegetable granules can be directly and sterilely added into the normal-temperature yogurt online. A fruit and vegetable granule product system and a normal-temperature yogurt system can be effectively compatible, the stability of the normal-temperature yogurt within the warranty period cannot be destroyed after the fruit and vegetable granules are added into the normal-temperature yogurt, and the fruit and vegetable granules are in a suspension state within the warranty period of the yogurt.

Description

technical field [0001] The invention belongs to the technical field of jam processing, in particular to a fruit and vegetable grain for adding normal temperature yoghurt and a preparation method thereof. Background technique [0002] Normal temperature fermented dairy products are favored by dairy processors and consumers because of their unique taste and flavor, no need for refrigeration, and convenient logistics, transportation and storage. Although fermented milk products at room temperature do not contain live bacteria, according to the conclusion of the World Dairy Federation (IDF) on fermented yogurt, the metabolites produced during the fermentation of yogurt have unique nutritional value and are the core of the nutritional value of fermented milk. It does not depend on the activity of lactic acid bacteria after the fermentation is completed. A large number of studies have shown that most of the lactic acid bacteria in traditional fermented milk are killed by gastric ...
