다시마 분말을 첨가한 쌀 압출팽화물의 최적제조조건을 설정하기 위하여 원료의 수분함량, 압출성형기의 barrel 온도, 다시마 첨가량의 변화에 따른 압출팽화물의 특성을 조사하였다. 수분함량 에서 높은 수분흡수지수, 낮은 텍스쳐 값을 나타내었고, barrel 온도는 에서 낮은 텍스쳐와 높은 팽화율을 보여 이화학적 특성이 좋았다. 쌀가루에 다시마를 첨가한 압출팽화물은 첨가량이 증가할수록 수분흡수지수는 감소하고 텍스쳐는 부드러워졌으며, 팽화율은 높아졌다

This study showed the optimum conditions for producing rice extrudate added with the sea tangle powder, and presented the effects of moisture content, barrel temperature and the amount of sea tangle powder. From the results, the more the amount of sea tangle powder was added, the less the water absorption ratio was showed, while the more the texture became smooth, the more the expansion ratio increased. From the sensory evaluation, the best preference was obtained when the moisture content was , and the barrel temperature was at . Between control and sea tangle, there was no significant difference in all observed parameters. But if more than sea tangle was added, low sensory evaluation scores were obtained due to the peculiar smell from sea tangle. From these results, addition of sea tangle below (w/w) did not affect the quality of products.
