Milk jelly samples made with six different gelling substances, agar, gelatin, l-carageenan, corn starch, sodium alginate and LM pectin, were prepared, and the physical properties of these samples were investigated. The rupture stress of all samples was the same. The rupture strain of the agar milk jelly was the lowest, while the values for the elasticity of the Hookean and Kelvin-Voigt bodies, and the viscosity of the Kelvin-Voigt body of the agar milk jelly were the highest. On the other hand, the values for the elasticity of the Hookean body and viscosity of the Newtonean body of the gelatin milk jelly were the lowest. The melting temperatures of the agar, LM pectin, l-carageenan and gelatin milk jelly samples were 84.1°C,55.8°C,52.3°Cand 30.3°C, respectively. While there was marked syneresis of the agar milk jelly, there was little with the alginate milk jelly and LM pectin milk jelly. A sensory evaluation judged the agar and gelatin milk jelly samples to be palatable, while the LM pectin and alginate milk jelly samples were judged to be unpalatable.
