Abstract

This study was conducted to investigate the effect of acetic acid and citric acid treatments on amount and content ratio of calcium (Ca) and phosphorus (P) which were extracted from beef shank bones. The amount of Ca in shank bone extracts significantly increased with increasing citric acid and acetic acid concentration, whereas the amount of P increased with only adding citric acid to extraction media. In the case of combined treatment with 0.2 % acetic acid and 0.1 % citric acid, the amounts of Ca and P increased to 30 and 400 %, respectively and Ca and P ratio were drastically improved from 7.53 to 1.85 compared with treatment of 0.2 % acetic acid. The sensory score of shank bone extract prepared with 0.2 % acetic acid and 0.1 % citric acid treatment showed the highest values in taste and overall acceptability among the tested shank bone extracts.

사골로부터 칼슘과 인의 용출량을 증가시킴과 동시에 칼슘의 흡수에 효과적인 비율로 칼슘과 인의 함량을 조절하기 위하여 초산과 구연산의 혼합효과를 조사하였다. 사골에 구연산과 초산을 각각 첨가하여 추출물을 제조한 결과, 구연산은 사골로부터 칼슘과 인을 유사하게 용출시키나, 초산은 인보다 칼슘을 선택적으로 용출시켰다. 초산 0.2 %와 구연산 0.1 %를 혼합하여 제조한 추출물은 초산 0.2 %의 결과에 비하여 칼슘의 용출량은 약 30 %($26.89{\rightarrow}34.22mg$) 증가하였으나 인의 용출량은 약 400 % ($3.57{\rightarrow}18.45mg$) 증가하였으며, 칼슘과 인의 비율은 7.53에서 1.85로 크게 개선되었다. 관능평가에서 맛과 전체적인 기호도는 0.2 % 초산+0.1 % 구연산을 첨가하여 제조한 시료가 증류수와 0.2 % 초산을 사용한 시료보다 우수하였다.
