초록
미숫가루에 가수시 엉기는 현상을 방지하고 분산성을 개선하기 위한 목적으로 미숫가루를 응집 처리한 결과는 다음과 같다. 미숫가루의 주성분은 탄수화물로서 약 67%에 달하였으며 수분함량이 약 7%, 조단백과 조지방이 각각 12.1% 씩이었고 회분이 1.9%이었다. 비처리 시료의 초기
The effect of agglomeration treatment was examined to prevent the parched cereal powder from clumping when it is blended with water. Parched cereal powder was composed of 66.9% carbohydrate, 7% water, 12.1% crude protein, 12.1% crude fat and 1.9% ash, respectively. Particle size of parched cereal powder was generally enlarged by agglomeration treatment. This phenomenon was confirmed by particle size analyzer and microscopic observation. The color of agglomerated sample was shown to be slightly darker than the untreated sample. The water absorption indices of agglomerated samples which were steamed for 2min and re-dried were significantly increased as compared with the untreated sample. The water solubility indices of agglomerated samples showed generally lower values than those of untreated samples. In views of quality and processing time, the optimum condition of agglomeration treatment for manufacturing well-dispersable parched cereal powder in water was 15min re-drying after 2min steaming. It is concluded that the agglomeration treatment improves the dispersibility of parched cereal powder and thus facilitates the intake of it after mixing with water.
