Freezing-Thawing Characteristics of Botanical Tissues and Influence of Water Morphology

A series of visualization experiments were conducted to investigate the transport phenomena and interface behaviour during the freezing-thawing process of typical botanical tissues. Attentions were paid to the growth of ice crystals and the advancing of the phase-change interface. The comparison was made to identify the freezing/thawing behaviour for different tissues under various freezing conditions. Based on the experimental observation, analyses were conducted to explore the influence of water morphology on the freezing/thawing characteristics.
