Abstract
Biopolymer such as hydroxypropyl methylcellulose (HPMC) itself did not possess any antifungal activity. To enhance its antifungal activity, Thai essential oils (EOs) were incorporated into HPMC-based nanocomposite coatings and tested in mangoes cv. Namdokmai Sithong against an anthracnose disease. A reduction in weight loss, firmness loss, changes in colors and higher soluble solid content were observed in the coated mangoes. The mangoes coated with HPMC-based nanocomposite coatings incorporated with the antifungal EOs exhibited a higher score of overall acceptance than uncoated ones. The shelf-life of coated mangoes was extended to 18 days at 13 °C. All essential oils from ginger, plai and fingerroot incorporated into the HPMC-based nanocomposite edible coating delayed losses caused by C. gloeosporioides better than from using the HPMC-based nanocomposite coating alone. Therefore, active HPMC-based nanocomposite coatings incorporating Thai essential oils can inhibit the growth of C. gloeosporioides and prolong the fruit shelf-life of mango fruit without an adverse sensory effect.
