Embodiment Construction

[0023] An example of this method is as follows:

[0024] 1. Preparation of auxiliary material a: In the batching tank 1, 10% fruit juice and 0.5% stabilizer are mixed vigorously through a colloid mill for 3 times, and then homogenized at a pressure of 18-35 MPa to obtain auxiliary material a.

[0025] 2. Raw milk pretreatment: Centrifuge and clean 83% of the raw milk, raise the temperature to 45°C, pump it into the batching tank 2, add 8% white sugar, and mix well.

[0026] 3. Ingredients: Pour auxiliary ingredient a into the ingredient tank 2 filled with milk and mix. Add 1.5% water to constant volume, and mix well to become the fermentation base material.

[0027] 4. Homogenization: After the fermentation base material is prepared, it is homogenized. Preheat to 55°C before homogenization, and the average pressure is 25MPa.

[0028] 5. Sterilization: The homogenized material is sterilized by heat preservation, the temperature is controlled at 95°C, and the ster...

Abstract

A preparation method of set-style yogurt containing acid juice (pH value of original juice less than or equal to 4) belongs to the technical field of food processing. The technology relates to a method which is used for preparing the set-style yogurt containing acid juice by taking fresh milk (or full-cream milk powder) and acid juice as raw materials. The preparation method comprises the following main processes: firstly mixing 3%-10% of acid juice and 0.3-0.8% of stabilizing agent into an auxiliary material a, and adding 6%-9% of white granulated sugar to 80-85% of milk liquid; mixing two feed liquids, metering the volume, sterilizing for 5-12 minutes at the temperature of 90 DEG C to 98 DEG C after heating and homogenizing, and cooling till reaching 42 DEG C to 45 DEG C for standby application; inoculating lactic acid bacteria into the prepared milk liquid containing the acid juice, filling and sealing covers; and keeping the inoculated milk liquid containing the acid juice warm at the temperature of 42 DEG C + / - 2 DEG C for 5.5 hours, and then refrigerating the milk liquid for 12-18 hours to obtain the product. The set-style yogurt prepared by the method integrates the nutrition of the acid juice and fruit juice and is unique in mouthfeel; no like products are sold on the market; and as the set-style yogurt has high added value and the production cost of the set-style yogurt is lower than that of stirred yoghurt, the set-style yogurt has a great market potential.

Description

technical field [0001] The method relates to a production technology of a coagulated yogurt product, which uses fresh milk (or whole milk powder) and acid fruit juice (pH value of the original fruit juice ≤ 4) as raw materials. The method belongs to the technical field of food processing. Background technique [0002] At present, all kinds of yogurt products are deeply favored by consumers because of their good flavor and rich nutrition. Traditional set yogurt has a long history and sells well, but it does not contain nutrients such as acidic juice (pH value of the original juice ≤ 4). At present, there is still a gap in the market for set yogurt products containing acidic juice (pH value of the original juice ≤ 4). In order to fill this gap and enrich the market demand, it is imperative to develop set yogurt products containing acidic juice. Contents of the invention [0003] The key technology of the method is to provide a method for making a new type of solidified yog...
