Abstract

This was studied to evaluate the rheology properties of the Dumpling shell added chitosans(commercial and prepared from fungal), polyphosphate, guargum and tapioca. The physicochemical properties of fungal chitosans (FCs95 and FCs 40) were as follows respectively. The nitrogen was 6.71% and 6.9％, the solubility 99.05% and 99.13％, the viscosity 2.23cps and 2.21cps, the acetylation 12.0% and 12.7% and the molecular weight 3.12${\times}$10$\^$5/Dalton and 3.01${\times}$10$\^$5/Dalton. From the above facts, the components and physicochemical properties of two kinds of fungal chitosan had little difference. The addition of polyphosphate, guargum and tapioca showed effect on the texture parameters(hardness, cohesiveness, springiness and gumminess) of Dumpling shell dough and the optimum addition concentration wag 0.074%, 6.59% and 0.062%(w/w), respectively. In case of chiotsans addition, texture of the dough by added SCs, FCs95 and FCs40 showed effect.

만두피의 반죽제조에 키토산(시판 키토산 및 제조 키토산) 및 폴리인산, 구아껌, 타피오카 등의 성분 배합비율에 따른 반죽의 물성변화를 알아보고자 하였다. 그 결과는 다음과 같다. 제조된 균류키토산의 수분함량은 6.57∼6.58%, 질소함량은 6.71∼6.91%, 용해도는 99.05∼99.13%, 점도는 2.21∼2.23cps, 아세틸화도는 12.0∼l2.7% 그리고 분자량은 3.01${\times}$$10^{5}$∼3.12${\times}$$10^{5}$Dalton으로써 산처리 온도에 따른 FCs40과 FCs95의 성분 및 물리화학적 특성의 차이는 거의 없는 것으로 나타났다. 만두피 반죽에 첨가하는 폴리인산의 적절한 농도는 만두피 전체 성분 첨가량의 0.074%인 것으로 나타났으며, 폴리인산의 첨가량이 적거나 많이 함유하였을 때는 만두피 반죽의 견고성, 응집성, 탄력성 및 점착성 등이 오히려 감소하는 경향이었다. 타피오카의 첨가량에 따른 반죽의 물성에는 큰 영향을 주지는 않았으나, 첨가량은 전체성분 중량의 6.59%정도, 또한 구아껌의 경우는 0.062%정도가 만두피 반죽의 물성에 적절하였다. 만두피의 물성에 효과적인 키토산은 고분자량의 SCs, FCs40 및 FCs95 등으로 나타났다.타났다.
