What are the different ways of stocking foods?

Food can be stocked in various ways, including refrigeration and freezing, which preserve freshness and prevent spoilage. Canning and bottling involve sealing food in airtight containers, extending its shelf life without refrigeration. Drying and dehydrating remove moisture to inhibit microbial growth, while vacuum sealing eliminates air for longer preservation. Additionally, fermentation can be used to extend the life of certain foods while enhancing their flavor and nutritional value.
