Canned foods are a staple 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 shelf life when properly sealed. The thermal processing parameters depend on the product's composition, with both physical and chemical changes occurring during processing and storage that affect sensory properties and nutrient content.

• Fresh produce (fruits, vegetables, meat, or fish) is harvested at peak quality and transported to the canning facility
• Produce undergoes thorough washing, peeling, trimming, and slicing before canning
• Prepared food is packed into cans moving along a conveyor system
• Liquid medium (brine, water, oil, syrup, or juice) is added to fill each can
• Lids are sealed and tested for airtight integrity
• Cans are cooked in specialized cookers at precise temperatures and pressures
• After cooling, cans are labeled and distributed to retailers
