Abstract


The present work introduces a preparation of coating fruits film from natural biodegradable materials with evaluation of its efficiency in keeping the quality of fresh date fruits. Triple blend (Tb) which involved PVA, chitosan (Cs) and tannic (TA) acids was studied in preservation of Rutab (Hyani) date. Antimicrobial characters besides decay of fruits during a cold storage were determined. The blend solutions were exposed to the γ-irradiation (5.0 to 20 kGy) before casting or use. The effects of polymer composition and irradiation dose on the mechanical and thermo-mechanical properties were studied. The obtained results showed that γ-irradiation and the addition of tannic acid (TA) increased the mechanical properties of the films and the shelf-life of Rutab (Hyani) date during the marketing period (12 ± 2 °C, 98%, RH) from one week to one month of marketing period for consumers with accepted freshness and quality.
