Abstract

To obtain the the processing technology of lotus root chips, taken lotus root as raw materials, the effects offreeze drying time, hot-air drying temperature and hot-air drying time on quality of lotus chips by combination of freeze drying and hot-air drying were explored. Experiment results indicated the optimized technological parameters of combined freeze dring and hot-air drying were freeze drying 4h, then hot-air drying at 50 ℃ for 2 h. At those conditions, the color value L*, a*, b* and hardness value of lotus root slices were 77.65, 0.96, 9.03 and 385.3 g, respectively. The results showed that combined drying technology combined freeze dring and hot-air drying were superior to the hot-air drying.
