8 ancient food preservation methods that are still practiced

Long before refrigerators and freezers became a part of our everyday kitchen life, the idea of food preservation had a different meaning and approach. Back in time, people around the world relied on traditional methods to keep food safe for longer periods. According to food experts, these ancient techniques not only helped prevent food spoilage but also enhanced flavour, nutrition, and minimised wastage. Interestingly, many of these time-tested practices are still effective and are used in Indian homes and kitchens across cultures. Take a look at these eight ancient food preservation methods that remain effective even in modern times.
