A novel edible coating material for the postharvest quality improvement of perishable fruit crops

Our research focuses on addressing the high rate of postharvest losses in fruits and vegetables in India due to factors such as traditional storage on farms, microorganism infestation, and limited availability of processing methods and cold chain facilities. To tackle this issue, we have developed a non-toxic and edible composite coating material made from wheat straw arabinoxylan (AX) and stearic acid derivatized oat bran β-glucan (SABG).

Our AX-SABG composite emulsion can be used to coat various perishable fruits, including apples, peaches, and bananas, to prolong their shelf life. Our coating formulation has proven to extend the post-harvest quality of various apple varieties, such as Royal Delicious and Rich Red Kinnaur, for up to 30-40 days at 22°C. Additionally, the formulation has extended the shelf life of peaches for up to 6-8 days and bananas for up to 9 days without significant blackening under ambient storage conditions.

Our coating material has undergone in vivo toxicological studies, which have shown that it is non-inflammatory and non-toxic. The coating technology is simple, cost-effective, and has the potential to be an alternative to commercially available animal-based shellac coating in India. Our innovation in developing non-toxic and edible fruit coating materials has the potential to significantly reduce postharvest losses and benefit the agricultural industry in India.

India is rapidly transforming into a dynamic hub of intellectual innovation and discovery. To support the science and technology ecosystem in the country, the Sree Padmavathi Venkateswara Foundation has created peer- reviewed funding programs that recognize exceptional researchers with the potential to achieve ground-breaking results in areas of critical national
importance. Our foundation provides these researchers with generous funding and empowering mentorship to generate knowledge and develop sustainable solutions of the highest quality, particularly in the fields of biomedical and agricultural research. We also work on projects to deploy advanced knowledge and improve the income of small and marginal farmers. We believe that by working together, we can create sustainable solutions that will benefit not only India but also the world.
