Abstract

This study was performed to investigate the utility of egg-shell calcium with calcium soak egg-shell in the vinegar. We compared examination eluted quantity with ionization rate in each condition. The results were as follows. 1 The degree of elution and ionization of calcium was proportional to the amount of vinegar and added acetic acid in the vinegar for elution. And ionization rate was the most high in case of 200 ml vinegar volume. 2. fluted quantity were increased in the rank order to 4$0^{\circ}C$ > 3$0^{\circ}C$ > 2$0^{\circ}C$ by temperature but the rank order of ionization of calcium was 3$0^{\circ}C$ > 2$0^{\circ}C$ > 4$0^{\circ}C$ by temperature. The occurrence of unacceptable flavor resulting from the immersion at 4$0^{\circ}C$ was another obstacle to adopt. 3. Eluted quantity and ionization rate of the egg-shell calcium were appeared excellent in case of the brewage vinegar at ventilation condition. The case of brown rice vinegar did not show a considerable difference, but eluted quantity and ionization rate were appeared the most excellent to the other sample. 4. The optimum condition for elution and ionization of the egg-shell calcium was appeared Immersing egg-shells in the brewed rice-bran vinegar at 3$0^{\circ}C$ for three days.

난각 칼슘을 천연의 칼슘 소재로 사용하는 방법으로 식초에 난각을 침지하여 흡수율이 좋은 칼슘 이온상태로 퐁출시키는 방법과 여러 가지 조건에 따른 용출량과 이온화율의 변화에 관한 비교 시험 결과는 다음과 같다. 1 식초를 이용하여 난각의 칼슘을 용출시키는 방법은 식초량과 식초에 함유되어 있는 초산량이 증가할 수록 용출량 또한 증가하는 것으로 나타났다. 또한 이온화율은 식초 200ml에 용출시키는 실험군이 가장 높게 나타났다. 2. 난각칼슘의 용출 및 이온화에 작용하는 요인 중 온도는 20~3$0^{\circ}C$일 때가 가장 효과적이며 4$0^{\circ}C$에서는 난각칼슘의 용출량은 증가하였으나 이온화 정도가 감소하는 것으로 나타났다. 또한 4$0^{\circ}C$에서는 식초에서 이취가 발생하는 현상을 나타내어 식품 첨가물로써의 활용에 문제가 있을 것으로 사료된다. 3. 난각 칼슘의 용출량 및 이온화율에 있어서 통기조건은 밀폐조건보다 우수한 것으로 나타났다. 그러나 현미식초의 경우는 유의적 차이를 나타내지는 않았으나 다른 실험군에 비하여 용출량과 이온화율이 우수한 것으로 나타났다. 4. 난각칼슘의 용출과 이온화를 위한 가장 최적의 조건으로는 3$0^{\circ}C$에서 현미식초 200ml에서 용출시키는 것이 가장 효과적인 것으로 나타났다. 아울러 이들 이온화된 칼슘의 흡수율에 대해서도 연구해 볼 필요가 있을 것으로 사료된다.
