摘要

本研究揭示了开发的以葫芦巴为基础的生物膜对提高易腐食品的保质期的作用。制备了几种不同的生物膜[葫芦巴:琼脂],即V0 (100:0), V1 (90:10), V2 (80:20), V3(70:30),并根据透明度和厚度以及其他功能特性进行了表征。获得的数据表明,与V2和V3相比,V1(2.50)的透明度更高。这些变化能够保留营养成分,即抗氧化性能、抗坏血酸、酚含量和重量损失百分比,与未包覆的样品相比,营养损失可以忽略不计。此外,使用伽马源照射样品,观察联合处理(生物膜和伽马辐射)的效果。记录观察显示涂层辐照样品(V1- Ir)的保质期延长了19天。本研究揭示了植物基生物膜和辐射提高易腐食品货架期的策略途径。

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