Foods that are retailed and stored at normal room temperature are called ambient food. This type of food has a longer shelf-life and fights harmful microorganisms with advanced heat treatment. Shelf life is the time span of food for which it can be kept under required conditions keeping in mind optimum quality and safety. It begins with manufacturing and depends on packaging type, ingredients, storage conditions, and manufacturing process among others. Generally, the shelf life of a food product is determined during the manufacturing process. Manufacturers determine the extrinsic and intrinsic of the food products that affect their quality and safety. These include manufacturing process, ingredients used, packaging type, and storage conditions among others. Two major processes for ambient food packaging are sterilization and pasteurization. Increasing competition for chill cabinet space signifies the increasing demand for food packaging that provides longer shelf life. The increasing trend towards sustainable packaging products is significant in the case of ambient food packaging. Different food packaging and preservation processes are used to increase product shelf life. Increasing the product’s acidity, decreasing its water content, and using airtight envelope can increase the product’s shelf life without changing its texture and taste.
