Embodiment 1

[0031]

[0032]

[0033] The ambient yogurt with whole blueberries is prepared by:

[0034] 1) Fermentation broth preparation: heat 50-55% of the total milk to 50-55°C, add white sugar (part), whey protein powder, acetylated distarch phosphate, gellan gum, agar, and milk In the process, use equipment with mixing, dispersing, shearing, and emulsifying effects to make the material liquid into a uniform and dispersed mixture. The time for mixing the material is kept at 15-20 minutes. Milk with part of the water separated); vacuum degassing (temperature: 55-65°C, vacuum degree of degassing: -0.3bar to -0.4bar) and homogenization (homogeneous temperature: 60-65℃, homogeneous pressure: 30 / 160bar), sterilization (temperature time: 132±1℃ / 4s), fermentation (temperature: 42-44℃, time: 5h-7h), strain: Lactobacillus bulgaricus (0.1U / kg) and Streptococcus thermophilus (0.05U / kg) to obtain a fermentation broth.

Abstract

The invention provides normal-temperature yoghurt containing whole blueberries and a preparation method of the normal-temperature yoghurt. The normal-temperature yoghourt is obtained by mixing blueberry jam and fermented milk, wherein the blueberry jam is prepared from the following raw materials: whole-grain blueberries, water, white granulated sugar, gellan gum, hydroxy propyl distarch phosphate, citric acid and sodium citrate; the blueberry jam is prepared by the following steps: hardening finished blueberries; mixing blueberries with white granulated sugar, gellan gum, hydroxy propyl distarch phosphate, citric acid and sodium citrate, boiling at 75-90 DEG C for 10-20 minutes, and sterilizing by adopting a coiled tube type sterilization machine to obtain the blueberry jam. The invention further provides a preparation method of the normal-temperature yoghourt. According to the technical scheme provided by the invention, the completeness of the whole blueberry grains in the product is ensured by optimizing a jam sterilization process.

Description

technical field [0001] The invention relates to room temperature yoghurt containing whole blueberries and a preparation method thereof, belonging to the technical field of yoghurt. Background technique [0002] Normal temperature yogurt is made from milk, after pasteurization, beneficial bacteria (lactic acid bacteria) are added to the milk, and after fermentation, the fermented milk is heat-treated again. The product is easy to carry and tastes good, and is deeply loved by consumers. [0003] The scientific name of blueberry is blueberry, which is called blueberry in Europe and the United States. It belongs to the shrub plant of Rhododendronaceae Vaccinium. Its fruit is a berry. Blueberries are rich in nutrients. Every 100 grams of fresh blueberries contain 400-700 mg of protein, 500-600 mg of fat, 12.3-15.3 mg of carbohydrates, and 81-100 IU of vitamin A. [0004] Among the existing products, there are many yogurt products containing blueberry pulp and blueberry jam. Th...
