Method for producing dairy product containing fruit grains by ohmic sterilization process

Abstract

The invention relates to a method for producing a dairy product containing fruit grains by adopting an ohmic sterilization process. According to the present invention, a fruit particle sterilization process method is mainly adjusted, such that a traditional fruit particle sterilization process is replaced with the Ohmic sterilization method, such that the heat treatment strength is reduced on the premise of food safety ensuring, the fruit particle freshness is ensured to the maximum extent, the mechanical loss caused by the traditional sterilization mode is reduced, the fruit particle damage degree is reduced, and the taste is ensured. The product adopting the ohmic sterilization process is generally superior to a traditional tube type fruit granule sterilization process and a scraper type ultra-high temperature sterilization process in terms of overall flavor, fruit taste and product color.

Description

technical field [0001] The invention relates to a method for producing dairy products by using an ohmic sterilization process, in particular to a method for producing a milk beverage containing real fruit tastes by using an ohmic sterilization process. Background technique [0002] At present, milk beverages containing fruit generally have problems such as small size of added fruit, soft texture and high degree of damage, which seriously affect the further upgrading of consumer experience and product quality. In response to this situation, the present application provides an ohmic sterilization method, which solves the problems of limited size of fruit particles, soft texture / high degree of damage of fruit particles caused by traditional sterilization methods, and excessive heat treatment, so as to ensure the fruit quality to the greatest extent. grain freshness. [0003] In the existing technology, due to the use of traditional fruit sterilization equipment and technology,...

Problems solved by technology

[0007] At present, some manufacturers apply ohmic sterilization technology to the sterilization process of pure liquid products; however, in pure liquid products, compared with traditional indirect sterilization, the advantages of ohmic sterilization technology cannot be fully reflected: 1) usually liquid thermal conductivity Excellent, fast heat transfer, the volumetric heating method of ohmic sterilization cannot give full play to its advantages; 2) The equipment designed according to the pure liquid product does not need to consider problems such as solid blockage, and the pipeline is usually designed to be relatively thin, and the heating efficiency can be effectively controlled by adjusting the flow rate. There is little difference between the heating speed of traditional partition-type sterilization and ohmic sterilization; 3) ohmic sterilization converts electrical energy into heat energy, which consumes more energy than industrial steam heating, and processing pure liquid products cannot reflect its technical advantages, so the overall economical not tall
