Why Preserve Food?
Food spoils because of: bacteria and fungi growth, chemical reactions (oxidation), moisture. Without preservation, we could only eat seasonal food! Preservation methods extend shelf life so food is available year-round. India wastes about 40% of its food each year โ preservation helps reduce this waste significantly.
