Five different concentrations of the compound ranging from 0.01 mg/ml, 0.05 mg/ml, 0.1 mg/ml, 0.5 mg/ml to 1.0 mg/ml were prepared in isopropanol. The antioxidant activities of octacosanol were studied at these concentrations for four in vitro assay systems including DPPH radical scavenging activity, reducing activity, metal chelation activity and inhibition of lipid peroxidation. Maximum antioxidant potency was displayed at 1.0 mg/ml for all the assays except the metal-chelation assay which demonstrated highest activity at 0.5 mg/ml. Octacosanol also showed anti-bacterial activities against Escherichia coli, Pseudomonas aeruginosa and Bacillus subtilis as observed by disc assay against concentrations of 1 mg/ml and 2 mg/ml. -

Received: 17 June 2020; Accepted: 20 July 2020; Published: 24 July 2020 Abstract: Liquid food adhesion on containers has increased food waste and pollution, which could be effectively alleviated with a superhydrophobic surface. In this research, the superhydrophobic coating was fabricated with edible soybean wax on different substrates by a spraying method. The coated surface showed excellent superhydrophobicity due to its microstructure formed by self-roughening, which could repel a variety of viscous liquid food with the apparent contact angle of 159 2 . ± ◦ The coated surface was still liquid-repellent after hot water immersion (45 ◦C), abrasion test with sandpaper, water impact, finger touch and immersion into yogurt. The liquid-repellent coating with soybean wax, which is natural and green, is promising for application in the food industry to reduce waste. Keywords: non-wettable coating; edible; soybean wax; residue 1. Introduction With the development of the economy, people’s living standards improved, especially in food demand. In daily life, viscous liquid food (such as yogurt, honey, milk, coffee, et al.) residue remain adhering to the container after drinking, which has given us a great deal of inconvenience and resulted in huge waste (up to 15% of liquid food products) [1]. -
