Study on water loss under low pressure and low temperature plasma

The objective of this study was to evaluate the effect of water evaporation under low pressure (1.2mbar) and low temperature plasma which provided a guide to the study of plasma sterilization and mutation. Materials were deionized water, skimmed milk, liquid medium. The result showed that, low temperature plasma obviously promoted water evaporation. The water evaporation was different in different materials (small tube) :deionized water>skimmed milk>liquid medium. Boiling tube was differed from small tube. The test group was significantly higher than blank group. There were two main effect happened:thermal effects of plasma and activation effect of steam by low temperature plasma excitation. The low-temperature plasma would as a new and broad prospect technique for the food industry.
