Abstract

Storage stability of the blue-green pigment, which was converted from Gardenia jasminoides yellow pigment by Staphylococcus epidermides and Gardenia jasminoides yellow pigment, were investigated at various conditions of light, temperature, inorganic ion and pH, The factors that cause the discoloration were light and temperature $(above\;40^{\circ}C)$. The effects of light and temperature on storage stability of blue-green pigment were less than those of Gardenia jasminoides yellow pigment. Also, the effect of light was decreased by using green filter. There were no significant effects of pH and inorganic ion on both pigments.

S. epidermidis에 의해 치자황색소에서 변환된 청녹계색소와 치자황색소의 저장안정성에 미치는 광, 온도, pH, 무기이온에 의한 영향을 조사하였다. 두 색소는 광과 $40^{\circ}C$ 이상의 온도조건에서 변색에 영향을 받았으나, 변환된 색소가 보다 안정성이 있으며, 광에 의한 영향은 green filter에 의해 감소시킬 수 있었다. pH와 무기이온에 의한 영향은 두 색소 모두 작았다.
