Abstract The objective of this study was to investigate the effects of ethanol on the physicochemical properties and microbial quality of fresh-cut sugarcane. Ethanol (300 mL/L) treatment resulted in the lowest weight loss, electric conductivity, and browning and the best quality attributes in fresh-cut sugarcane. It also significantly reduced the activities of polyphenol oxidase, phenylalanine ammonia-lyase and peroxidase and decreased total phenols and quinines contents. The total bacterial count and yeast mold count showed that there was significant suppress of microbial spoilage in fresh-cut sugarcane with ethanol treatment. Ethanol treatment increased the CO 2 production and decreased O 2 level inside the package environment compared to treatments that combined ethanol (300 mL/L) and ascorbic acid (10 g/L) as well as the control (distilled water). Ethanol was the most efficient approach to inhibiting enzymatic browning and controlling microbial growth on fresh-cut sugarcane.
