What does ultra high temperature sterilization do |
Posted: December 13, 2022 |
Milk and occasionally other dairy products are heated to around 137° Celsius for only 4 seconds during ultra-high-temperature pasteurization, after which they are quickly cooled back down. Utilizing UHT milk processing equipment, the procedure is sometimes known as UHT pasteurization or simply ultra-pasteurization. Both hazardous and regarded-as-beneficial bacteria in dairy are known to be killed by high heat. The benefits of pasteurization have come under scrutiny because of this. The FDA claims that pasteurization has little impact on the nutritional value of the food. However, the milk does wind up tasting a little bit "cooked." Unprocessed milk is typically not recommended for consumption by those with various conditions, including cancer, due to the potential for increased health risks from the milk's dangerous bacteria. The only solution in that situation will be sterile, secure ultra-pasteurized dairy. Additionally, if you don't drink milk frequently, ultra-pasteurized milk (in unopened Packs) can be kept in your refrigerator for a very long period. An aseptic unit and a sterilizer are necessary for ultra-high temperature sterilization (for packaging the product). It is used for low-acid (above pH 4.6) goods like soy milk, UHT milk, UHT flavored milk and other dairy substitutes. Food, such as soups, sauces, sweets, tomatoes, fruit preparations, and baby food, are likewise sterilized using the same procedure. In the early 1800s, high-heat processing and canning were invented in France to preserve food. Tin-coated steel vessels were commonly used by 1839. Packaging developed its own continuous UHT process and aseptic packaging methods in the 1960s, expanding on this early food preservation technology, which helped to expand the ultra-high temperature sterilization milk market. UHT treatment aims to maximize microbial elimination while minimizing chemical alterations in the product. This entails determining the ideal temperature and processing time combination for various food varieties. Product Packaging provides two more UHT treatment options: direct and indirect. Steam is temporarily introduced into the product during direct UHT heating, swiftly followed by flash cooling. The short duration of the treatment allows for very good product quality. In contrast to indirect UHT treatment, the process consumes a fair amount of energy. Indirect heating involves employing heat exchangers to warm the product rather than having it in direct contact with the heat source. The fact that most of the thermal energy can be recovered makes this technology so affordable. Changes Occurred in Milk During UHT
Optimizing food safety and production versatilityHow can heating technology, including heat exchangers, offer the best quality for a growing number of products? What are heat load parameters appropriate for your new products' shelf life? The guide to heating technology explains how to optimize your heating system for better product quality, increased energy effectiveness, and lower total cost of ownership. Download it today if you're prepared to reconsider how you use heat to create food. Selecting the proper pasteurization method for your dairy product requires careful consideration of several factors. You must consider the product you are pasteurizing, the quality and composition of its raw materials, the kind and composition of its packaging, the viscosity, the anticipated temperature profile, the flow rate, and any pressure drops that may be present. To consider this a solution for your requirements, you must have the appropriate UHT pasteurization equipment.
