쌀전분겔의 매트릭스와 구조를 안정화하고 텍스쳐 특성을 개선하기 위하여 멥쌀전분에 다양한 검물질을 혼합하여 겔을 제조하여 형태적, 텍스쳐 특성, 냉동-해동 안정성을 비교하였다. 검물질을 첨가하면 종류에 따라 다르나 쌀전분겔을 조밀하고 균일하여 안정된 매트릭스 갖게 할 수 있었으며 겔란검과 알긴이 효과적이었다. 쌀전분/검질 혼합 겔의 텍스쳐 특성도 검질에 따라 달랐으며 겔란검은 단단하고 알긴은 부드러운 겔을 형성하였다. X-선 회절도에 의하면 쌀전분겔은 V형의 결정형을 나타내며 검을 첨가하였을 때 $2 heta$ = $20^{o}$의 피크가 낮아졌다. 냉동-해동 안정성도 검물질을 혼합하였을 때 증가하였으며 겔란검과 알긴을 첨가한 쌀전분겔이 바람직 하였다.
To improve the textural properties and stabilize the structure and gel matrix of non-waxy rice starch gels, non-waxy rice starch/gum mixture gels were prepared from various food gums, gum arabic, guar, algin, deacyl gellan, xanthan and gellan gums. The morphological and textural properties and freeze-thaw stability of their gels were compared. Rice starch/gum mixture gels with various gums formed a more homogeneous gel matrix with smaller particle size than rice starch gel without Em, but the trends differed depending on the gum types. The textural properties of rice starch/gum mixture gels were changed with the gum types. The shape of the rice starch/gum mixture gel matrix was desirable when mixed with gellan and algin. The textural properties of gels hardened in the rice starch/algin mixture gel and softened in the rice starch/algin mixture gel. The rice starch gels showed V-type crystallinity by x-ray diffractometer, but the peak at $2 heta$ = $20^{o}$ was decreased with increasing gum addition. The freeze-thaw stability increased with increasing gum addition. Gellan and algin were especially effective.
