Food Preservation

Food preservation is the process of treating and handling food to stop or greatly slow down spoilage (loss of quality, edibility or nutritive value) caused or accelerated by micro-organisms. Maintaining or creating nutritional value, texture and flavor is important in preserving its value as food.
