Abstract
Pregelitinized rice (PR), pregelitinized waxy rice (PWR), and pregelitinized rice flour (PRF) were evaluated for physico-chemical properties comparing with rice starch and acetylated potato starch. L value was decreased during drum drying. PFR had the highest value (P<0.05) for water absorption index and PWR had the highest value for water solubility index. Transmittance of gelitinized samples had drastically increased at
드럼건조에 의한 쌀가루의 특성을 알아보기 위해 멥쌀, 찹쌀, 및 멥쌀쌀가루를 드럼건조하여 멥쌀전분 및 감자초산전분과 비교, 검토하였다. 드럼건조시 L값이 감소하였으며, 수분흡수지수는 호화쌀가루가 가장 높았고(P<0.05) 수분용해지수는 호화찹쌀이 가장 높았다(P<0.05). 호화된 시료는
