Aseptic packaging is a method used to preserve food and beverages by keeping them free from harmful microorganisms. This process involves sterilizing both the product and the packaging separately before they are combined in a sterile environment. This helps to extend the shelf life of products without the need for refrigeration. Commonly used for items like juice, milk, and soup, aseptic packaging allows these products to remain safe and fresh for months or even years. The packaging is typically made from materials like plastic, paperboard, and aluminum, which are designed to protect the contents from light, air, and moisture.
