canning technology

Canning technology preserves food by sealing it in airtight metal or glass containers, then applying heat to kill bacteria, yeast, and molds that cause spoilage. This process creates a vacuum seal that prevents new microbes from entering, extending the food’s shelf life while maintaining its flavor, texture, and nutrients. Modern canning uses specific temperatures and durations based on food type to ensure safety and quality. It’s a reliable method for long-term storage, allowing people to enjoy seasonal foods year-round without refrigeration.
