Characterization of Bio-Degradable Plant Based Film to Enhance the Shelf Life of Perishable Food

Abstract

The present study discloses the role of developed fenugreek-based biofilms to enhance shelf life of perishable foods. The biofilms were prepared in different variations [fenugreek: agar] i.e. V0 (100:0), V1 (90:10), V2 (80:20), V3 (70:30) and are characterized on the basis of transparency and thickness along with other functional properties. Obtained data indicated better transparency for V1 (2.50) in comparison with V2 and V3.The variations were able to retain nutritional contents viz., antioxidant property, ascorbic acid, phenolic content and percentage weight loss in coated sample with negligible nutrient loss compared to that of uncoated sample. Further, the samples have been irradiated using gamma source, to observe the effect of combined treatments (biofilm and gamma radiation). Recorded observation depicts enhanced shelf life of coated – irradiated sample (V1- Ir) for 19 days. The current study discloses the strategic approach of plant-based biofilm and radiation in improving shelf life of perishable foods.
