Canned foods are an essential dietary component in developed countries, offering convenient, year-round availability. The canning process uses heat treatment to destroy microorganisms while preserving food quality, resulting in products with an indefinite microbiological shelf-life when properly sealed.

The thermal processing parameters (temperature and duration) depend on the product's chemical and physical composition. Both physical and chemical changes occur during processing and storage, affecting sensory properties and nutrient content. These quality-determining changes are influenced by processing time/temperature, food composition, canning medium, and storage conditions.

• Fresh produce (fruits, vegetables, meat, fish) is harvested at peak quality and transported directly to the canning facility
• Produce undergoes thorough washing, followed by preparation steps (peeling, trimming, coring, slicing) before can filling
• Cans are filled with appropriate liquid (brine, water, oil, syrup, or juice) and sealed airtight
• Sealed cans are cooked at precise temperatures and pressures to eliminate microorganisms while preserving nutrients
• After cooling, cans are labeled and distributed to retail outlets
