Problems solved by technology

Most of the common fermented milks currently on the market need to be stored under refrigerated conditions, and the products are in a liquid state or an unstable solid state, which is inconvenient to carry and transport
If the existing yoghurt is directly dried under normal pressure, the solid dairy product obtained will have strong toughness, will not melt for a long time after the entrance, and will have a poor taste

Abstract

The invention provides a method for preparing a normal-temperature solid dairy product, comprising: preparing fermented milk; cooling the fermented milk to 2 to 6°C and standing it for 4 to 20 hours to obtain aged fermented milk; whipping the aged fermented milk Aeration, whipping and aeration with an expansion rate of 110% to 200% to obtain aerated fermented milk; forming the aerated fermented milk and freezing it at -80 to -75°C for 1 to 2 hours to obtain frozen fermented milk; and The frozen fermented milk is dried to a moisture content of 2% to 5% to obtain a solid dairy product at room temperature. The present invention also provides a room temperature solid dairy product with a moisture content of 2% to 5%; the protein content of the fermented milk is 4.0% to 5.0%, and the fat content is not higher than 0.45%. The room temperature solid dairy product provided by the invention can produce a unique taste of "melt in the mouth" when it is ready-to-eat, and can be stored at room temperature.

Description

technical field [0001] The invention relates to a dairy product and a preparation method thereof, in particular to a normal temperature solid dairy product and a preparation method thereof. Background technique [0002] Fermented milk is a product made from raw cow (goat) milk or milk powder, which is sterilized and fermented to lower the pH value. It is a common dairy product, easy to digest and absorb, and is a high-quality protein source. Most of the common fermented milks currently on the market need to be stored under refrigerated conditions, and the products are in a liquid state or an unstable solid state, which is inconvenient to carry and transport. If the existing yoghurt is directly dried under normal pressure, the solid dairy product produced will have strong toughness, will not melt for a long time after being imported, and will have poor mouthfeel. Contents of the invention [0003] The object of the present invention is to provide a method for preparing a n...
