Abstract: This article analysed the freezing properties of ginger while taking air as freezing medium by testing its freezing points under different low-temperatures.The impact of scalding and freezing velocity on the texture of products were also studied. The results showed that the temperature below -40℃ satisfies quick-freezing, while scalting process makes the freezing point rise but the freezing time spent on zone of maximum crystallization dose not change obviously while the temperature is below -40℃.

Key words: ginger, quick freezing, scalt, zone of maximum crystallisation
