preparation example Construction

[0023] Based on the above-mentioned probiotic yogurt, the present invention also provides a preparation method for the probiotic yogurt, the specific preparation steps are as follows:

[0024] 1) Heat the raw milk to 45-55°C, add inulin and white sugar, continue to heat up to 60-70°C, and then filter through a filter to obtain the raw material base liquid;

[0025] 2) After pouring the raw material base liquid into the sterilizer for sterilization, preheat at a temperature of 55~65°C;

[0026] 3) Pour the preheated raw material base liquid into the homogenizer, and homogenize under the condition of a pressure of 8~10MPa;

[0027] 4) Heat the homogenized raw material base liquid to 90~95°C, keep it warm for 3~8 minutes, and then cool it to 40~45°C;

[0028] 5) At a temperature of 42~43°C, inoculate the probiotics into the raw material base liquid, then stir and ferment evenly until the pH value reaches 4.2~4.5, stop the fermentation, and cool the product to 15~ within 30 minut...

Embodiment 1

[0037] Ingredients of raw milk: 100g of fresh milk, 1.2g of whole milk powder, 1.34g of food additives, 3.5g of concentrated whey protein, 30mg of taurine, 3mg of niacinamide, and 0.8mg of zinc citrate.

[0038] Among them, the food additives are sodium carboxymethylcellulose, polydextrose, citric acid, lactic acid, sodium tripolyphosphate, sodium citrate, guar gum, glycerol monostearate fatty acid ester, sucrose fatty acid ester, aspartame Blend of Sweet (with Phenylalanine), Acesulfame K, Natural Vitamin E, Xanthan Gum, or Emulsified Silicone Oil.

[0039] The above-mentioned ingredients are transferred to a pressurized concentration tank through a balance tank, concentrated under reduced pressure, and solids are strengthened by adding milk powder to obtain milk, wherein the added amount of milk powder is 2% of the total weight of the above-mentioned ingredients, and the remaining The following preparation process is the same as step 1) to step 5) in the above preparation me...

Embodiment 2

[0042] Ingredients of raw milk: 100g of fresh milk, 1.2g of whole milk powder, 1.34g of food additives, 3.5g of concentrated whey protein, 30mg of taurine, 3mg of niacinamide, and 0.8mg of zinc citrate.

[0043] Among them, the food additives are sodium carboxymethylcellulose, polydextrose, citric acid, lactic acid, sodium tripolyphosphate, sodium citrate, guar gum, glycerol monostearate fatty acid ester, sucrose fatty acid ester, aspartame Blend of Sweet (with Phenylalanine), Acesulfame K, Natural Vitamin E, Xanthan Gum, or Emulsified Silicone Oil.

[0044] Whole preparation process is identical with embodiment 1.

[0045] Wherein, the content of inulin is 20% by weight based on the weight of the probiotic yoghurt, and the probiotic is a mixed strain of Streptococcus thermophilus and Bifidobacterium.

Abstract

The invention discloses probiotic yogurt and a preparation method thereof. The probiotic yogurt contains inulin the content of which is 0.1-20% by weight. The probiotic yogurt is prepared by the following steps of preparing materials, preheating, homogenizing, sterilizing, inoculating and fermenting, has the advantages of regulating the balance of human intestinal microecology, improving function of intestines, controlling the blood fat, improving the immunity of human bodies and being high in dietary fiber content and the like. Moreover, the preparation process is simple, and is easy to operate.

Description

technical field [0001] The invention relates to yogurt, and in particular provides a probiotic yogurt and a preparation method thereof. Background technique [0002] There are hundreds of kinds of microorganisms in the human body, and the microbial flora that is beneficial to the human body in the intestinal tract are called beneficial bacteria, that is, probiotics. Probiotics can effectively maintain the micro-ecological balance of the intestinal tract. However, many factors such as aging, disease, and antibiotic treatment can cause the imbalance of the micro-ecological system in the intestinal tract, leading to human diseases. Studies have found that artificial supplementation of active beneficial bacteria can not only regulate the imbalance of intestinal microecology, make it tend to balance, restore and maintain human health. It can also enhance human immunity; promote intestinal peristalsis and help digestion; inhibit the growth of spoilage bacteria; reduce the risk o...
