| Abstract: | The physico-chemical and nutrition properties of four types of carrot powder, obtained respectively by hot air drying (HAD), short- and medium-wave infrared drying (S&MID), vacuum microwave drying (VMD) and vacuum drying (VD), were compared and discussed. Results showed that a* value (redness to greenness) and rehydration ratio of carrot powder produced by different drying methods followed the decreasing order: S&MID ＞ VD > VMD > HAD. The oilholding capacity of carrot power obtained by four drying methods had no significant differences. The highest total sugar content and β-carotene contents were observed in S&MID carrot power, and VD carrot power was the richest in VC. In summary, short- and medium-wave infrared drying is suitable for industrial production of carrot powder due to the excellent product quality. |
