RHEOLOGICAL PROPERTIES OF AIGYOKUSHI GELS

Changes in the rheological properties of "Aigyokushi" gels stood at room temperature were studied. 1) The values for textual properties of the slime extracted within 15 min were very high and gelation occurred, but then they decreased by syneresis, and after a considerable amounts of water were released from the gel, the values increased again a little. 2) The value for the strain of Hookean body of "Aigyokushi" was the highest after standing for 2 h, however, the strain of Voigt, Newtonean and plastoelastic body, was lowest at that time, respectively. 3) Both in the syneresis rate and total amounts of water released from the gels within 10 h were greater than those of low methoxyl pectin gels. However, the calcium and galacturonic acid contents in the released water of "Aigyokushi" gels were lower than those of low methoxyl pectin gels.
