Abstract
Food packaging is one of the unswerving method in food containment to assure and control the factors that can affect the food safety, quality and shelf life. The combination of antioxidant and antimicrobial property that the mango peel extract material is an excellent innovation in active packaging material in guaranteeing those factors. This study specifically aimed to develop an active antioxidant and antimicrobial packaging material utilizing extract from mango (Mangifera indica var. carabao) peel. The mango peel was subjected to maceration method with ethanol to obtain mango peel extract. The mango peel extract was subjected to different analyses such as DPPH Scavenging Radical Activity and Total Phenolic Content. The total phenolic content of the extract was 116.05 mg gallic acid equivalent (GAE)/g. The highest antioxidant activity recorded among the concentrations is 96.85% in 100ppm of the mango peel extract. The effective concentration in which the mango peel extract can scavenge the half of the DPPH radicals is 11.26 ppm. The films were characterized according to its weight, moisture, thickness and solubility and showed no significant differences among the varying concentrations. The films with 1000 mg extract of mango peel showed the highest DPPH radical scavenging activity at all periods and attained the highest percentage of 91.5423% at 420 minutes. The films with and without mango peel extract showed no zone of inhibition implying the negative antimicrobial property. The extract can be commercially exploited as natural antioxidants. It can also be incorporated in products such as packaging films to enhance their antioxidant activity and help retard rancidity of food products.
