This work aims at investigating effect of different pretreatments and varied temperature on the drying kinetics, bioactive compounds, antioxidant activity, microstructure and functional group of apple slices using pulsed vacuum dryer. Pretreated apple slices (Ethanol, US + W, and US + E) dried at varied temperature (60, 70, and 80°C) were analyzed to determine total phenolic content (TPC), total flavonoid content (TFC), 1,1-diphenyl-2-picrylhydrazyl (DPPH+), 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid color, microstructure and FT-IR spectroscopy. The findings revealed that US + E pretreatment significantly decreased drying time. US + E pretreatment retained TPC, TFC, DPPH+ and ABTS+ than Ethanol, US + W, and control and was further corroborated by the observed peaks as revealed by the FT-IR spectroscopy. However, drying often leads to a reduction in quality parameters as well as degradation of nutritional components of the apple. Novel pretreatment techniques like ultrasonic aided ethanolic pretreatment preceding to apple drying provides an added advantage over conventional drying methods in that it reduces dehydration time as a result of faster moisture removal, lowers energy consumption, improves process efficiency leading to industrial competiveness and it also preserves the nutritional and sensorial parameters of dried apple slices.
