Abstract
This study evaluated the effects of microwave vacuum drying (MVD), microwave drying (MD), heat pump drying (HPD), hot air drying (HAD), and freeze drying (FD) on the drying kinetics, and changes of physicochemical properties and bioactive compound of Orah slices. In the analysis of the seven models examined, the Page model was found to be the most accurate in describing the changes in moisture content during the drying process. MD was significantly faster than HAD and HPD, reducing drying time by 95.12 and 94.17%, respectively, and increasing the effective moisture diffusion rate by 94.40%. Microscopic analysis showed MVD samples had large, uniform pores, which improved moisture diffusion. FD and MVD preserved bioactive nutrients and demonstrated superior antioxidant activity over other methods. MVD produced products with balanced texture, minimal color change, and the shortest drying time of 38 min. MVD can be a promising dehydration technique for producing high-quality Orah products.
期刊介绍：
The FSB journal covers food chemistry and analysis for compositional and physiological activity changes, food hygiene and toxicology, food microbiology and biotechnology, and food engineering involved in during and after food processing through physical, chemical, and biological ways. Consumer perception and sensory evaluation on processed foods are accepted only when they are relevant to the laboratory research work. As a general rule, manuscripts dealing with analysis and efficacy of extracts from natural resources prior to the processing or without any related food processing may not be considered within the scope of the journal. The FSB journal does not deal with only local interest and a lack of significant scientific merit. The main scope of our journal is seeking for human health and wellness through constructive works and new findings in food science and biotechnology field.
