멥쌀전분, 찹쌀가루, 멥쌀전분으로 제조한 RS3형 저항전분의 수분 함량은 비슷하였으나, 단백질 함량, 회분 함량, 지방질 한량은 찹쌀가루가 가장 높았다. 멥쌀전분으로 제조한 RS3형 저항전분의 RS함량은 9.10% 이었다. 멥쌀전분으로 제조한 RS3형 저항전분을 첨가한 인절미 경도와 부착성을 레오메타로 측정하였을 때 저장기간과 RS3형 저항전분의 첨가량이 증가할수록 증가하였다. 관능검사 결과, RS3형 저항전분을 첨가한 인절미의 경도가 무첨가 인절미보다 높은 값을 보였으나, 탄성, 부착성, 부드러움성, 전체적인 품질은 RS3형 저항전분의 첨가량에 따라 유의적인 차이를 보이지 않았으며, 전체적인 품질은 경도와 음의 상관관계를 보였다(r＝-0.331, p＜0.05).
The objective of this study was to compare the textural properties and sensory evaluation of Injulmi, a traditional Korean waxy rice cake, added with 10, 20 and 30% of RS3-type resistant starch. RS3-type resistant starch was prepared from nonwaxy rice(Odaebyeo) starch by autoclaving-cooling cycle. The RS yield of RS3-type resistant starch was 9.10%. By increasing the addition level of RS3-type resistant starch, the hardness and adhesiveness of Injulmi increased as measured by using a rheometer. Hunter color L and a values of Injulmi added with RS3-type resistant starch were increased, but b value was decreased. In case of sensory evaluation, the hardness of Injulmi added with RS3-type resistant starch was higher than that of non-added Injulmi. The overall duality of Injulmi added with RS3-type resistant starch by sensory evaluation was negatively correlated with the hardness measured by rheometer(p＜.0.05).
