Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the defect that there are no live bacteria in yogurt at room temperature in the prior art, because lactic acid bacteria continue to grow in yogurt at room temperature, resulting in poor product state and taste, and the product cannot be stored at room temperature. The defect that lactic acid bacteria must be killed , providing a live bacteria room temperature yogurt with live bacteria and a preparation method thereof

Embodiment 1

[0032] formula:

[0033]

[0034] The process steps are as follows:

[0035] 1. Heat the milk to 40°C, add sucrose and whole milk protein powder, and keep stirring for 30 minutes;

[0036] 2. Heat up the material obtained in step 1 to 60°C, homogenize at 60°C and 20Mpa, and then sterilize at 90°C for 600s to obtain a fermentation substrate;

[0037] 3. Cool the fermentation substrate obtained in step 2 to 39° C., add a starter, and insulate and ferment until the terminal acidity is 80° T;

[0038] 4. Add 7.4% (w / w) fructose syrup to the fermented milk in step 3, stir for 5-10 minutes, fill and store at room temperature.

[0039] The protein content in the raw material is 4.69%, pH: 4.78.

Embodiment 2

[0041] formula:

[0042]

[0043] The process steps are as follows:

[0044] 1. Heat the milk to 50°C, add sucrose, modified starch, and agar, and keep stirring for 15 minutes;

[0045]2. Raise the temperature of the material obtained in step 1 to 65°C, after homogenizing at 65°C and 18Mpa, sterilize at 135°C for 5s to obtain the fermentation substrate;

[0046] 3. Cool the fermentation substrate obtained in step 2 to 43°C, add a starter, and insulate and ferment until the terminal acidity is 70°T;

[0047] 4. Add 5.2% (w / w) fructose syrup to the fermented milk in step 3, stir for 5-10 minutes, fill and store at room temperature.

[0048] The protein content in the raw material is 2.95%, pH: 4.35.

Embodiment 3

[0050] formula:

[0051]

[0052] The process steps are as follows:

[0053] 1. Heat the milk to 50°C, add sucrose, whole milk protein powder, modified starch, and pectin, and keep stirring for 15 minutes;

[0054] 2. Heat up the material obtained in step 1 to 60°C, homogenize at 60°C and 25Mpa, then sterilize at 90°C for 600s to obtain the fermentation substrate;

[0055] 3. Cool the fermentation substrate obtained in step 2 to 40°C, add a starter, and insulate and ferment until the terminal acidity is 75°T;

[0056] 4. Add 30% (w / w) jam (25% sugar content) to the fermented milk in step 3, stir for 5-10 minutes, fill and store at room temperature.

[0057] The protein content in the raw material is 3.81%, pH: 4.55.

Abstract

The invention discloses a living bacteria type normal temperature yoghurt and a preparation method thereof. The raw materials of the living bacteria type room temperature yogurt include conventional raw materials of yogurt, wherein the content of sucrose is 0.6-0.8%, and the content of protein in the raw materials is 2.95-4.69%; ; The starter of the yogurt is the brand Acidifix TM Starter; the specific steps include: 1) mixing raw materials other than starter; 2) homogenizing and sterilizing the materials obtained in step 1) to obtain a fermentation substrate; 3) cooling the fermentation substrate in step 2), and adding fermentation 4) adding sucrose-free sweetening substances to the fermented substrate in step 3), stirring evenly, and filling to obtain live bacteria type normal temperature yoghurt. The yogurt breaks through the technical barrier of no live bacteria in yogurt at room temperature, and the acidity, state, taste, and lactic acid bacteria count remain stable during the shelf life at room temperature.

Description

technical field [0001] The invention relates to the field of dairy products, in particular to live bacteria type room temperature yoghurt and a preparation method thereof. Background technique [0002] In recent years, yogurt has been favored by consumers for its good taste and physiological functions. Yogurt is a food made from milk as the main raw material and fermented by lactic acid bacteria. Because the live bacteria itself has a probiotic effect and many physiologically active substances are produced during the fermentation process, yogurt not only has all the advantages of milk, but also adds many nutrients beneficial to the human body on this basis, taking into account all the benefits of fermented products. benefit. Yogurt is a food with good health functions. Its health functions mainly include: regulating gastrointestinal flora, improving the body's immune system, inhibiting tumors, lowering cholesterol levels, inhibiting toxins in the body, and delaying body ag...
