preparation example Construction

[0034] See attached figure 1 , a kind of preparation method of yogurt, comprises the following steps: 1) the preparation of starch liquid: add water in starch, mix uniformly, make the starch liquid that weight concentration is 5-15%; 2) the preparation of fruit and vegetable slurry: in step 1) Add maltodextrin and 6-8 parts by weight sweetener to the obtained starch liquid, stir evenly, heat at 80-90°C for 5-10min, then add fruit and vegetable pulp, and heat at 85-95°C , heated for 1-5min, cooled to 30-50°C to make fruit and vegetable slurry; 3) saccharification of sweetener: add water to the remaining sweetener, the weight of water is 2-3 times the weight of sweetener, Stir and saccharify at 45-60°C to make an aqueous sugar solution; 4) Preparation of emulsion: add water to the milk powder, the weight of the water is 4-7 times the weight of the milk powder, and stir at 40-50°C 5) Preparation of fermented liquid: add the aqueous sugar solution obtained in step 3) to the emuls...

Embodiment 1

[0041] Prepare yogurt as follows:

[0042] 1) Preparation of starch liquid: take 4 parts by weight of potato starch, add water to the starch, mix evenly, and make a starch liquid with a mass concentration of 10%;

[0043] 2) Preparation of fruit and vegetable slurry: In the starch liquid obtained in step 1), 4 parts by weight of maltodextrin and 4 parts by weight of xylitol are stirred evenly, heated at 80° C. for 10 minutes, and then 20 parts by weight of Mango pulp, heated at 85°C for 5 minutes, and cooled to 50°C to make mango pulp;

[0044] 3) Saccharification of aspartame: take 10 parts by weight of aspartame, add water to the mixture, the weight of water is 3 times of the weight of aspartame, stir and saccharify at 45°C to make aspartame sweet water solution;

[0045] 4) Preparation of emulsion: get 30 parts by weight of milk powder, the milk powder is a mixture of whole milk powder and skimmed milk powder, add water in the milk powder, the weight of water is 7 times o...

Embodiment 2

[0050] 1. Prepare apple pulp by following steps:

[0051] a) Soaking: Wash the apples, peel and core them, and soak them in the soaking solution for 50-70 minutes. The mass ratio of the soaking solution to the apples is 2:1-10:1. The soaking solution consists of vitamin C, citric acid, salt and water. Composition, the mass concentration of vitamin C in soaking liquid is 0.2%, the mass concentration of citric acid is 0.2%, the mass concentration of salt is 0.5%;

[0052] b) blanching, using the soaking solution obtained in step a) as a blanching solution, and blanching the apples obtained in step a) in the blanching solution. When blanching, the temperature of the blanching solution is 98°C, and the blanching time is 40s. The mass ratio of blanching liquid to apples is at least 20:1;

[0053] c) Cooling, cooling the apples obtained in step b) to below 20°C, and performing pulping to obtain apple pulp; the obtained apple pulp also undergoes a probiotic fermentation step, and th...

Abstract

The invention discloses yoghourt and a preparation method thereof, relates to the technical field of yoghourt, and aims to solve the problems that existing yoghurt is inconvenient to store and carry, and single in nutrient ingredient. The yoghourt is prepared from the following raw materials in parts by weight: 30-50 parts of milk powder, 14-28 parts of a sweetening agent, 0.2-0.5 part of lactic acid bacteria powder, 20-30 parts of fruit and vegetable pulp, 3-5 parts of maltodextrin, 1-4 parts of starch and 4-6 parts of collagen peptide powder. The preparation method for the yoghourt comprises the following steps: preparing a solution, mixing, fermenting, homogenizing and performing freeze-drying. The yoghourt disclosed by the invention is dried solid-form circular or heart-shaped yoghourt, convenient to store and carry, long in quality guarantee period, high in lactic acid bacteria content, beneficial for restoring the equilibrium of floras in a human intestinal tract and promoting intestinal tract movement, rich in dietary fiber, capable of cleaning the intestinal tract, promoting digestive absorption and timely supplementing lost collagen peptide for a human body, beneficial for preventing osteoporosis, free of sugar, and especially suitable for the middle aged and elderly people with diabetes to eat.

Description

technical field [0001] The invention relates to the technical field of yogurt, in particular to yogurt and a preparation method thereof. Background technique [0002] With the improvement of living standards, people no longer worry about food and clothing. However, the requirements for food are getting higher and higher, and people are paying more and more attention to food safety, health and nutrition. As one of the nutritious products, yogurt has a good taste and is deeply loved by people. [0003] The existing production process of yogurt is as follows: fresh milk or milk powder is fermented at 40-45°C through batching, standardization, sterilization, cooling, refrigerated at 2-6°C, aged, and inspected before leaving the factory; this yogurt is all liquid , its lactic acid bacteria are easily inactivated, and those that need cold chain transportation and sales have a short shelf life and are inconvenient for people to eat; moreover, cold yogurt is not suitable for people...
