Disruptions in supply chains resulting from blockages on transport routes, transport restrictions and quarantine measures are resulting in significant increases in food loss and waste, especially of perishable agricultural produce such as fruits and vegetables, fish, meat and dairy products.

With physical distancing and reduced shopping trips to supermarkets, buying large quantities of fresh fruits and vegetables becomes difficult, with the risk of them going to waste, during this COVID-19 pandemic. There are, however, simple ways in which fruits and vegetables can be preserved at home to reduce waste. Many vegetables, can be blanched by dipping in boiling water for approximately 5 minutes and then pickled and fermented. Fruits can be preserved by blanching and freezing, juicing, drying, frying, or preserved with sugar into jams and fruit preserves.
Root crops and bananas can be fried to produce chips.
