Antioxidant, Antibacterial Analysis of Pectin Isolated from Banana Peel and its Application in Edible Coating of Freshly Made Mozzarella Cheese

The present study aimed to evaluate the antibacterial, antioxidant activity of pectin extracted from banana peel. Antibacterial activity was investigated against Staphylococcus aureus, Escherichia coli, and Salmonella Enteritidis. The well diffusion method was used to assess the antibacterial effect of the pectin extract on microorganisms. The extract showed maximum activity against Staphylococcus aureus (19.6 mm). The total phenolic content and flavonoid content in the examined extract found to be 3883.6 mgGA/g and 903.03 mg QE/gm on a dry matter basis. Antioxidant activity is analyzed using in vitro Standard spectrophotometer methods. Pectin extract increases DPPH scavenging activity up to 75 μg/ml of concentration. The innovation in food packaging by the use of pectin-based edible coatings is reviewed in this paper. Thereafter, coating of pectin was done in mozzarella cheese and its shelf life was studied at 1, 7,14,21, and 28 days of storage at 5 ̊C. It was analyzed that pectin coating over mozzarella cheese increases their shelf life from 7 to 21 days. Thus, pectin is a natural polysaccharide that attracts interest for maintaining and improving the quality of cheese. Also, it minimizes the waste that occurs from non-biodegradable Original Research Article Tripathi and Mishra; AFSJ, 20(7): 82-92, 2021; Article no.AFSJ.69376 83 packaging materials and helps the environment to be safe. This research was carried out at the laboratory of Food Science analysis Laboratory, Babasaheb Bhimrao Ambedkar University, Lucknow (INDIA) between February 21-April 21.
