Abstract

The aim of this study was to determine the content of water-soluble vitamins in various parts of beetroot (pulp, leaves and stems) that had been subjected to various drying methods in a bid to explore the effect of physical processes, i.e., the application of ultrasound, on micronutrient preservation. The experiments were performed at the Department of Service Technologies of Tashkent State Technical University, and chromatographic analysis was performed in the Institute of Bioorganic Chemistry of the Academy of Sciences of the Republic of Uzbekistan. Chromatography was performed on Agilent-1200 chromatograph with Exlipse XDB C18 column and diode array detector using a detection wavelength of 250 nm. Acetate buffer-acetonitrile elution gradient of flow rate 0.8 ml/min and temperature 25 °C was used for the separation. Seven samples were analyzed: three of beetroot pulp (control sample, without treatment; conventional drying; drying with ultrasonic device), two of leaves (with and without ultrasonic device) and two of stems (with and without ultrasonic device). All samples were dehydrated at 55°C, with the final moisture content being 10-17%. Ultrasound (20-30 kHz) application diminished considerably the drying time as well as the water-soluble vitamin retention, particularly B1, B2, B6 and C. These results show that ultrasound treatment is an interesting alternative for dehydration of beetroot in order to maximize the conservation of bioactive compounds. These findings are of great interest for beetroot by-products food valorisation for the agri-food industry.
