Phase Characterization of Cucumber Growth: A Chemical Gel Model

الملخص EN

Cucumber grows with complex phenomena by changing its volume and shape, which is not fully investigated and challenges agriculture and food safety industry.

In order to understand the mechanism and to characterize the growth process, the cucumber is modeled as a hydrogel in swelling and its development is studied in both preharvest and postharvest stages.

Based on thermodynamics, constitutive equations, incorporating biological quantities, are established.

The growth behavior of cucumber follows the classic theory of continuous or discontinuous phase transition.

The mechanism of bulged tail in cucumber is interpreted by phase coexistence and characterized by critical conditions.

Conclusions are given for advances in food engineering and novel fabrication techniques in mechanical biology.
