멸치액젓제품의 풍미, 색택개선 및 유통중 불용성 침전생성 억제를 위한 기초자료를 얻기 위하여 멸치액젓을 활성탄, 활성백토. 알루미늄옥사이드, 규조토 및 celite의 농도를 달리하여 첨가하고 상온에서 60분간 교반한 후 0.45$mu$m membrane filter로 감압여과 한 다음 탈색률, 총질소, 아미노태질소, 불용성질소, TMA 및 침전생성 억제율을 측정하였다. 탈색율은 활성탄과 활성백토를 첨가하였 때 높았으며 $5\%$ 첨가농도에서 $32~33\%$의 탈색효과를 나타내었으나 TMA 함량은 각 처리구에서 $7\%$ 이하의 감소를 나타내어 탈취효과는 기대할 수 없었다. 멸치액젓 저장중 침전물의 생성억제 효과는 $5\%$ 처리농도에서 활성백토 $82\%$, 규조토 $73\%$ 및 $Al_2O_3$ $70\%$로 나타났다.
To obtain the basic data for the improvement of flayer and color in salt-fermented anchovy (Engraulis japonicus) sauce and for the inhibition of non-soluble precipitates formation during storage, experiments were carried out on the changes of chemical properties by treatment with 1, 3, 5 and $7\%$ (w/v) of active carbon and filter aids such as active clay, $Al_2O_3$ diatomaceous earth, and celite. Deceleration rate were $32~33\%$ in case of $5\%$ (w/v) active carbon or $5\%$ (w/v) active clay treatments, but deodoration effect was not expected in all treatments. The inhibition rate of non-soluble precipitates formation in me of $5\%$ (w/v) active clay, diatomaceous earth and $Al_2O_3$ treatments. was shown as $82\%,;73\%$, and $70\%$, respectively.
