Konserve refers to the process of preserving food by sealing it in airtight containers, often using heat to kill bacteria and enzymes that cause spoilage. This method allows food to be stored for long periods without refrigeration, making it a popular choice for home canning and commercial food production. Common items that are conserved include fruits, vegetables, and meats. The process typically involves cooking the food, placing it in jars or cans, and then sealing it to create a vacuum. This technique is essential for ensuring food safety and extending the shelf life of products like jams, pickles, and sauces.
