Abstract

The purpose of this study was to evaluate the antioxidant, antibacterial, and anti-UVB of three kinds of fermented fruit peel extracts by pectinase enzyme, including pomegranate, pomelo, and banana peel. The antioxidant was evaluated by the DPPH (2,2-Diphenyl-1-picrylhydrazyl) free radical scavenging method. Antibacterial activity against Escherichia coli and Staphylococcus aureus was assessed by disk diffusion assay, and the photoprotective activity was measured using a photospectrometric method. The results revealed that pomegranate peel extract at 3000 IU/g peel exhibited potent free radical scavenging property against DPPH, with the smallest IC50 value at 0.18%, which was better than that of pomelo peel extract at 55.79%. Furthermore, the results suggested that the pomegranate peel extract also exhibited antibacterial activity against E. coli better than pomelo peel extract, but none of the three samples shows the antibacterial capacity against S. aureus. Moreover, 10% pomegranate peel extract also expressed the strongest anti-UVB activity, with an SPF value of 36.582. The research demonstrates pomegranate peel’s bioactivity potential for further experiments.

Summary

Introduction

People all around the world consume a huge amount of fruit every year. Much research has demonstrated the importance of fruit peels in a variety of aspects, such as fertilizer, biofuel, enzymes, food, or cosmetics. There were about 102 million tons of banana consumed in 2018, and the peel represents the 35% of the weight. Banana peel waste has been used as a medicinal source for the treatment of anemia, diabetes, inflammation, and cancer, due to its high amount of phenolic and fiber [1]. Pomelo peel contains many bioactive compounds, such as coumarins and flavonoids, polyphenols, and vitamins, that impact health benefits beyond basic nutrition [2]. According to Zhai et al [3], pomegranate is a popular fruit with a variety of products, such as juice, wine, and jam, in which its peel contains a large amount of phenolics, flavonoids, and tannins, which are commonly used in medicine
