Palaniappan and Sastry reported that the infiltration of a salt solution might increase the conductance of vegetables while, in contrast, the leaching out of ions from vegetable tissue during immersion in water may decrease conductance. Halden et al. (1990) monitored conductance during the blanching of vegetables and suggested that the destruction of cell walls released cytoplasm contents thus changing the conductance value. Later, Wang and Sastry suggested that the infiltration of salt solution to improve the conductance of vegetable tissue.
