Ascorbic acid retaining using a new calcium alginate-Capsul based edible film

Abstract

This work aimed to produce a new calcium alginate-Capsul edible film with antioxidant incorporated in matrix. The vitaminic stability was evaluated in the films during their storage under different conditions for 140 days. The films were characterized with respect to their mechanical properties and surface morphology. The results indicated a 25.6% of vitamin C incorporation in matrix during the film preparation. The films stored under refrigeration in the dark did not show a decrease in the vitaminic retention. The films stored under room temperature in the dark and in the bright/dark cycles exhibited significant decreases in the vitamin retaining from the 84th and 70th days, respectively. The vitamin C addition significantly decreased the tensile strength in the new pellicle. The results of the microscopy revealed a cohesive matrix in the new edible films. These results support the utilization of the new pellicle to protect ingredients, although more studies are necessary.
