The invention discloses normal-temperature yogurt and a preparation method thereof. According to the normal-temperature yogurt, the
viscosity is 200-250cp, the
total protein content by
mass percent is2.56%-3.03%, the
fat content by
mass percent is 3.5%-6.0%, the
carbohydrate content by
mass percent is 4.76%-12.14%, and the acidity is 70-90 degrees T. The preparation method of the yogurt comprisesthe following steps: uniformly mixing 81.491%-93.327% of pre-sterilized antibiotic-free milk, 4%-8% of a
sweetening agent, 2.25%-8.61% of light cream and 0.42%-0.84% of a stabilizing agent by a
vacuum mixing mode, homogenizing the mixed liquid, and performing
pasteurization on the homogenized liquid, wherein the percentages are the mass percentages of the components in the mixed liquid; cooling the sterilized mixed liquid, adding 0.003%-0.009% of a
starter and 0%-0.1% of essence, performing fermenting, wherein the percentage is the mass percentage of the
starter in the mixed liquid, and performing
emulsion breaking when the acidity reaches 70-90 degrees T to obtain a yogurt base material; and performing homogenization and
pasteurization on the yogurt base material for the second time, wherein the sterilization temperature is 70-80 DEG C and the sterilization time is 10-40s, performing cooling to 20-30 DEG C after sterilization and performing
nitrogen-filled filling. The product is high in
fat content, suitable for young people to drink and smooth and delicate in
mouthfeel.
