Potential of Fermented Fruit Peel Liquid in Cosmetics as a Skin Care Agent

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.

Investigation and Characterisation of New Eco-Friendly Cosmetic Ingredients Based on Probiotic Bacteria Ferment Filtrates in Combination with Alginite Mineral

“…DPPH scavenging results are shown in Table 2, Similarly to the results of [30]. IC50 values represent the amount of the filtrates, which reached 50% inhibition, so the lower the value, the better the result is.…”

From Industrial Food Waste to Bioactive Ingredients: A Review on the Sustainable Management and Transformation of Plant-Derived Food Waste

“…Industrial plant-derived food waste could represent, for the cosmetic field, an important natural source of biodegradable, skin-friendly, and environmentally friendly ingredients, such as proteins, polysaccharides, lipids, fibers, vitamins, phytochemicals, and minerals, that can exert either functional or technical activities, including antioxidants, moisturizing, nourishing, antiwrinkle properties, thickening, stabilizing, etc. [158][159][160].…”
