Recently, clarification of the rheological characteristics of gelatinous materials has become important since they are closely related to the fields of ultrafiltration, expression, immobilization of enzymes or bacteria, gel permeation chromatography and the like. In these fields, gelatinous materials are generally applied by compressive stress. Therefore, in the present work, the rheological behavior of gelatin gel under compressive stress was investigated. The two-element Voigt model is usable in this case. The elastic modulus and the viscosity were calculated by the model and the effects on them of compressive stress, gelatin concentration, temperature and pH were experimentally investigated.
