Effect of Different Essential Oils on the Properties of Edible Coatings Based on Yam (Dioscorea rotundata L.) Starch and Its Application in Strawberry (Fragaria vesca L.) Preservation

Every year the world loses about 50% of fruits and vegetables post-harvest in supply chain. The use biodegradable coatings films with antioxidant properties has been considered an excellent alternative to extend shelf life food. Therefore, objective this work was develop a coating based on yam (Dioscorea rotundata L.) starch-containing lime, fennel, lavender essential oils strawberries (Fragaria vesca l.). tensile properties, barrier (water vapour permeability (WVP) oxygen (OP)), moisture content, water-solubility, absorption capacity, water contact angle, optical activity resultant starch-based were evaluated. After that, active assessed inoculated Aspergillus niger during 14 days storage at 25 °C. results showed that incorporation improved elongation WVP provided capacity antimicrobial films. In particular, oil lime higher activity. This fact caused unwanted modification other such as decrease strength, elastic modulus increase OP. present study revealed potential incorporated into polymeric starch matrix produce (antioxidant antimicrobial). Obtained be viable protect them against niger.
