Development of Kamaboko-folding Tester

Abstract

Kamaboko-folding tester was designed to evaluate elasticity of kamaboko gel by an objective folding test. In the folding tester developed here, a sample of disk type (3cm diameter, 3mm thickness) was first once-folded to 6-7mm thickness, and after a prescribed time (1, 5 or 10s), twice-folded to 6.5-8.5mm thickness. The tester was reliable and sufficiently utilizable for quality control of kamaboko manufacturing. The force required to fold a sample, however, was remarkably influenced by the thickness of the sample, therefore, it should be needed to make its thickness accurate to obtain good correlation between quality of the sample and time-force curve during folding.
