Physicochemical Properties of Lotus (Nelumbo nucifera) Root Slices Dehydrated with Polyethylene Glycol

다국어 초록 (Multilingual Abstract)

Lotus root slices were dehydrated with polyethylene glycol (PEG) 4000. The PEG-treated samples had better results than those of freeze dried or hot-air dried samples in terms of rehydration ratio and color. The total phenolic content of the PEG-treated samples was higher than that of the freeze dried or hot-air dried sample. The microstructure of the PEG-treated samples was better than that of the freeze dried or hot-air dried one. These results suggest that lotus root slices can be dehydrated with PEG 4000 without loss of functional components and dehydrated lotus root be applicable as functional cosmetic ingredient.
