| description | Edible composite coatings based on hydroxypropyl methylcellulose (HPMC), lipid components (beeswax and shellac), and food preservatives with antifungal properties were evaluated in vivo on clementine mandarins cv. Clemenules, hybrid mandarins cv. Ortanique, and oranges cv. Valencia. Their curative and preventive activity against citrus postharvest green (GM) and blue molds (BM), caused by Penicillium digitatum (PD) or Penicillium italicum (PI), respectively, were determined. Fruits were artificially inoculated before or after the application of the coatings and incubated up to 7 days at 20 degrees C. Selected food preservatives included mineral salts, organic acid salts, parabens, and 2-deoxy-D-glucose. Inoculated but uncoated fruits were used as controls. For curative activity, HPMC-lipid edible composite coatings containing sodium benzoate (SB) were most effective in reducing the incidence and severity of GM on clementine mandarins cv. Clemenules (86 and 90%, respectively). On this cultivar, the reduction in GM incidence by the SB-based coating was twice that of potassium sorbate (PS)-based coating. On mandarins cv. Ortanique, PS- and SB-based coatings reduced the incidence of GM and BM by more than 40 and 21%, respectively. However, the HPMC-lipid coating containing a mixture of PS and sodium propionate (PS + SP) exhibited a synergistic effect in the reduction of the incidence of GM (78%) and BM (67%). Coatings with parabens modestly reduced disease incidence and severity. On oranges cv. Valencia, coatings with food preservatives better controlled BM than GM. Coatings containing SB + PS and SB + SP reduced the incidence and severity of BM by 85% and 95%, respectively. PS- and SB- based coatings controlled GM more effectively than coatings formulated with other food preservatives. In every cultivar, fruit coated before inoculation did not show any incidence or severity reduction of both GM and BM (preventive activity). In every test, the antifungal action of the coatings was fungistatic rather than fungicidal. |
