Research Projects

Edible films and coatings have existed and being used since decades but the rising demands of consumers for quality and fresh foods as well as eco-friendly packaging, have given rise to increased development of edible films. Starch and protein based composite edible films are becoming an eco-friendly substitute to petroleum based polymers because of its low cost, biodegradability and capacity to form flexible films with improved properties. Bioactive starch and protein based composite films with antimicrobial and antioxidative properties can prolong the shelf-life by lowering the microbial load and maintaining the freshness of food products. In this project, we first develop composite edible films from Vicia villosa (vetch) starch and protein which is recognized as underutilized cereal variety. Followed by the incorporation of polyphenolic Nano-particles from Celtis australis (hackberry) which is also considered as an underutilized berry. Developed films will be characterized on the basis of different parameters followed by their application on different fruits and vegetables. These products in turn will be categorized for general quality parameters. As already mentioned vetch seeds are underutilized despite of being a rich source of carbohydrate and protein so, its utility for edible packaging would prove to be an efficient approach to improve global food quality and preservation. Also, we highlight the importance of underutilized hackberry as a source of polyphenols. So, it will serve as a source of active packaging and offers longer shelf life, reduction in food waste, limiting oxidation and loss of color, smell and taste.
