4. Conclusions
The novel technique of USV drying markedly accelerated the drying process and reduced energy consumption compared to vacuum drying techniques. Furthermore, the rehydration potential, nutritional value, color, and textural properties of USV-dried carrot slices were greatly improved when evaluated against vacuum-dried carrot slices. In future research, the effect of this novel drying technique on the functional and nutritional properties of different food materials will be investigated.
