Abstract
The screening test of the kamaboko gel-strengthening effect was made with Na and Ca salts of polyuronides and carboxymethyl cellulose (CMC), in addition to cellulose. It was found that Ca salts of alginic acid, pectic acid, pectinic acid, and CMC increased the breaking force of kamaboko obtained from the surimi of Alaska pollack, whereas their Na salts except Na-pectinate did not. The increase in the breaking force induced by Ca-CMC disappeared by increasing its degree of sub-stitution of hydroxyl groups to carboxymethyl groups. Furthermore, fine particles of cellulose (400 meshes) increased the breaking force and breaking strain, and decreased the expressible water, but were ineffective when the particles became coarser. Under the presence of potato starch, even coarse particles of cellulose were effective. The breaking force was not so increased by increasing the ratio of CaCl2 to NaCl to be added to the surimi.
