Definition and Function of Food Packaging
Food packaging refers to the use of appropriate materials, containers, processes, decorations, structural design, and other means to wrap and decorate food in order to maintain its quality or increase its commodity value during the processing, transportation, storage, and sales of food. Its main functions include:
Protecting food and extending its shelf life:
Protect the appearance quality of food and prevent damage during handling, loading and unloading, transportation, and storage.
Protect the original quality of food and prevent food spoilage caused by microbial growth, moisture changes, oxidation, and other factors. Through techniques such as aseptic packaging, high-temperature sterilization, refrigeration, and moisture-proof packaging, the shelf life of food can be effectively extended.
Circulation and sales of convenience foods:
Some packaging itself is a container for food circulation, such as bottled alcohol, beverages, canned goods, etc., which brings great convenience to food circulation.
Packaging can increase the variety of food, facilitate consumer selection, and promote the exchange of local famous foods.
Preventing food contamination:
Packaging can prevent food from coming into contact with containers and human hands during circulation, which is beneficial to consumers' physical health.
Promoting the rationality and planning of food circulation:
For perishable fresh foods such as fruits and aquatic products, canning them at the production site can reduce waste, lower transportation costs, and promote the rationality and planning of food circulation.
