Refrigeration and Home Freezing: A refrigerator is needed for this method. A deep freezer can also be used. Fish, meat and milk are most preserved using this method. This method slows down bacterial actions but don’t totally stop it. Food in the refrigerator can last for one or two days, while the ones in the freezer can last for three or more days.

Canning: Keeping food canned significantly extends its lifespan – but only if done correctly. The canning process preserves food by removing oxygen through an airtight seal and containing food in an acidic, sugary, or salty environment, where bacteria cannot thrive
