This happened a few days ago. As I was at work and I needed a hand for my tasks so I requested my colleague but he didn’t respond, his face was filled with nervousness. Seeing his worried look, I asked him what was wrong. He replied that his son was not well as he had loose milk. He kept complaining about the how unhealthy milk is these days. That it is not hygienic enough to drink.  If it is not hygienic, how can it be nutritious? Where can we get a proper clean wholesome milk? How will we know the milk is reliable enough to drink? These questions were to heavily think about. So I started researching whenever I got a chance and came across aseptic processing and packing. This method is for liquid food products, enabling otherwise easily spoiled food items to be packaged, distributed and stored for long periods without the need for cooling or additives. In the aseptic process, liquid foods and drinks are sterilized by rapidly heating up to ultra high temperatures and equally rapid cooling before packaging or filling. Tetra Pak aseptic packaging provides high-quality packaging and long life to the products. They use UHT process (Ultra High Temperature)  the milk is heated at a high boiling point and quickly cooled in 3-4 seconds. In this way, the germs and bacteria in the milk are killed without losing its taste, look and nutrients. This process helps the milk stay clean and away from germs when the package is not opened. But Remember! Once opened, it should be stored in the fridge and consumed in the same conditions. When it is not opened, the product in Tetra Pak has a shelf life of 3 months and should be consumed in 2-3 days. The UHT products does not contain any preservatives. Thanks to UHT and aseptic packaging technologies, the milk has long life and aseptic package prevents milk from external factors such as air and light as well.
