Resumen
Physicochemical, antifungal and antioxidant properties of a pectin e aloe mucilage e candelilla wax e Larrea tridentata polyphenols based bioactive film were evaluated. Antifungal capacity was analyzed against Botrytis cinerea, Colletotrichum gloeosporioides, Fusarium oxysporum and Alternaria alternata. The main antioxidants in Larrea tridentata polyphenols were identified by HPLC-MS. Water vapor permeability (WVP) was measured in the film. Antioxidant capacities for ABTS$þ, DPPH$ , lipid oxidation inhibition (LOI) and ferric reducing antioxidant power (FRAP) (97, 92, and 57 %, 0.73 mM Fe, respectively) were evaluated. It was possible to determine the MIC50 for the fungi evaluated at concentrations of 558e612 ppm of polyphenols. Antioxidants identified were nordihydroguaiaretic acid (NDGA), Quercetin, and Kaenpherol. Treatment with 1.1 % of pectin, 0.16 % candelilla wax, 0.3 % glycerol, 5 % AM and 4 % extract of polyphenols showed values of thickness and WVP suitable to be applied on model fruits.
