Abstract

The invention discloses processed cheese with a long shelf life and a preparation method thereof. The processed cheese comprises the following raw materials: 3-7% of casein, 50-65% of natural cheese, 1-3% of whole milk powder, 1.5-2.5% of emulsifying salt, 8-10% of butter and the balance of water. The preparation method comprises the following steps: uniformly premixing casein, whole milk powder, emulsifying salt and butter to obtain an auxiliary material; dicing natural cheese to obtain cheese blocks; mixing the premixed auxiliary materials, cheese blocks and water, stirring and heating, and keeping the temperature to obtain crude cheese sauce; homogenizing the obtained crude cheese sauce to obtain a mixture; carrying out ultrahigh-temperature instantaneous sterilization on the mixture to obtain a cheese base material; and carrying out spray drying on the obtained cheese base material through a spray tower to obtain cheese powder, cooling and canning. The preparation method is simple in production process and easy to operate; the prepared processed cheese can meet the requirements of multiple scenes such as catering and household use, is convenient to eat, can be stored at normal temperature, has a shelf life of 2 years, and is stable in state and good in texture and taste.

Description

technical field [0001] The invention relates to the technical field of dairy processing, in particular to a processed cheese with a long shelf life and a preparation method thereof. Background technique [0002] Processed cheese is a product made from cheese as the main raw material, adding emulsifying salt, with or without adding other raw materials, and through processes such as heating, stirring, and emulsification. The "National Food Safety Standard Processed Cheese" GB25192-2010 stipulates the microbial limit index (n=5, c=2, m=100, M=1000). In industrial production, the shelf life is extended by pasteurization, ultra-high temperature instantaneous sterilization and adding preservatives. Currently, processed cheese on the market needs to be stored at a low temperature of 4°C, and the shelf life is 6-9 months. Considering the expansion of cold chain transportation, cold chain storage costs and sales scope, it is of great economic value to solve the bottleneck of low te...
