Making of extruded noodles mixed with soymilk residue

두유박을 이용한 압출면의 제조

For the improvement of the nutritive value of extruded noodles, dry soymilk residue flour (DSRF) was mixed with wheat How. The effects of the addition of DSRF on the viscosity of wheat flour and the quality of cooked noodles were evaluated As the proportion of DSRF addition was in-creased the viscosity of composite flour was decreased And so were the texture and cooking quality of noodles. To improve noodle-making characteristics of extruded noodles with 10% DRFF, Na-alginate, Na-carboxymethyl cellulose, guar gum crude gluten and xanthan gum were added. Then, the noodle-making characteristics were examined. The viscosity increased with the increase in the concentration of additives and Bnnthan gum was the most effective. The texture of noodles supplemented by Na-alginate 2.0%, Na-carboxymethyl cellulose 2.0%, guar gum 2.0%, xanthan gum 1.0% was similar to that of wheat flour noodles. The results of sensory test (color and texture) was coincidal with the results of instumental tests.

압출면의 영양강화 목적으로 두유박을 제면 원료인 소맥분과 섞어 점도 특성을 고찰하고, 압출면을 제조한 후 조리시험, 조리면의 조직감 시험 및 관능검사를 통하여 알아본 결과 두유박 첨가 비율이 증가함에 따라 복합분의 점도, 조리면의 조직감 및 조리 품질은 감소하였다. 두유박 10% 첨가 압출면의 제면 특성을 향상시키기 위하여 각종 첨가제의 첨가효과를 보면, 첨가제의 첨가량이 증가함에 따라 점도는 증가하였으며, 첨가제중에서는 xanthan gum이 가장 효과적이었다. 조직감에 있어서는 Na-alginate 2.0%, Na-carboxymethyl cellulose 2.0%, guar gum 0.5%, xanthan gum 1.0%가 좋을 결과를 나타내었다. 관능검사도 이와 유사한 결과를 보였다.
