Reducing post-harvest losses through nanotechnology

India is the largest producer of mangoes, but a short shelf life and poor handling can mean 35% in post-harvest loss, or $33 billion every year. These losses strain local producers, who rely on exports for their livelihood. But researchers are developing nanotechnology applications, of hexanal, a natural plant extract, to slow ripening by three weeks and double the shelf life of mangoes. Smart packaging systems slowly release hexanal to extend shelf life and prevent market glut so farmers can demand premium prices and increase incomes up to $100 per hectare per year. The additional income is used to cover education and health expenses and to buy more nutritious foods for their families. Now researchers are scaling up by working with institutions in Kenya, Tanzania, and Trinidad and Tobago.
