The purpose of any pasteurization process is to eliminate pathogenic bacteria from the milk. All the while preserving the product’s integrity for consumer satisfaction.
While many opinions on milk treatment are universally available, in this article, we will be discussing the benefits of the UHT aseptic high-temperature processing combined with aseptic filling.
The high-temperature treatment is generally in the range of 137-142℃ and will kill all the bacteria, molds, and yeasts that might spoil the milk at ambient conditions. The UHT aseptic processing is the step needed before aseptic packaging the milk.
When combined with aseptic filling equipment, the UHT process for Dairy products poses little risk for post-processing environmental contamination. The expiration date on these products is ~ 6 months at room temperature when stored on shelves. The products’ life is not extended more than that because the milk’s sensory characteristics gradually degrade with time. And not because of its possible spoilage but due to bacteria.
The Benefits of UHT-processing and Aseptic Packaging
The treatment of milk at Ultra-high temperatures can provide several benefits to the packaging and shelf life of the UHT-treated milk. The following benefits of UHT processed milk are easily noticeable and can help save you time and offer health-related advantages following the processing and consumption.
Short UHT Processing Time
Sterilization causes the milk to be safe, nutritious, and yet stored at room temperature without needing refrigeration. This happens because, once the UHT sterilization process is done at UHT temperature with a very short holding time of a few seconds, the quantity of microorganisms in the milk becomes almost zero.
The time it takes to further process the milk is also decreased as the impurities, as well as non-friendly organisms, have previously been eliminated. This means that you can then make yourself a cup of tea or coffee within a few minutes.
Long Shelf Life
Milk, when sterilized, lasts for a more extended period than it does in its raw or unprocessed form. Immediately after the UHT milk processing, the milk is packaged into containers that can be stored conveniently for many days. The UHT-treated milk contained inside the air-tight packaging stays fresh for almost nine months. However, the users are advised to consume it immediately once the package is opened.
Safer Than Untreated Milk
With the UHT milk processing, any heat-resistant bacteria in the milk gets eliminated, which then ensures its safety for you and your family. Processed milk is also readily available for use, making it the preferred choice for customers concerned about time and energy, for finding the right dairy products easily.
As UHT milk processing equipment manufacturer, we design equipment that can be used during the processing of premium quality aseptic products. The state-of-the-art UHT milk processing plant can be used for treating heat-sensitive dairy products such as white milk, milkshakes, flavored milk, buttermilk, and non-dairy products like soya milk, fruit juice and concentrates, sauces, and more.
