Curcumin and PLA-curcumin coating's chromaticity and colour stability in reaction to the effectiveness of pH

Understanding the limitations and unfavourable conditions of curcumin would be an advantage to increase the stability of the pigment. Therefore, the ultimate objective of this research is to evaluate the effects of pH on chromaticity and stability of curcumin and PLA-curcumin extracted from Curcuma...
