| Abstract | The aim of this study was to investigate the effects of drying method on shatavari quality and energy consumption. In this study, microwave powers of 1,000 and 1,500 W were used in combination with hot air at 60 ฐC. Drying on a tray at 60 ฐC was used as the traditional drying method. Fresh and blanched Shatavari roots with a sliced thickness of 3 mm were used for drying. The sample was dried until the free water content was less than 0.6. Then, the quality was analyzed, i.e., color values L* a* b* hue angle and chroma, and total phenolic content and total flavonoid content. The result showed that fresh Shatavari dried with a 1,000-W microwave dryer had the highest L* value, while the a* value and b* value were the lowest. The total phenolic content (TPC) and total flavonoid content (TFC) were highest in the drying without blanching and in the 1,000-W drying. When considering energy consumption, only the hot air dryer consumed the highest specific energy consumption (SEC) (0.30 MJ/kg), and increasing the microwave power resulted in a decrease in energy consumption. In addition, energy consumption was lower with blanching than without blanching. In terms of energy and quality, drying fresh Shatavari at a microwave power of 1,000 W combined with hot air at 60 ฐC was the appropriate condition |
