You preserve fruits and vegetables in the home to keep them from spoiling. This allows you to use them at a later date. Many people grow vegetable gardens during the summer and preserve them by canning or freezing to eat during the winter. Foods are commercially preserved to prevent spoilage during transportation to markets and while sitting on the shelf until they are sold.
