Abstract Natural colorant extracts were obtained by extraction from tumeric root, gardenia
seeds, mugwort and green tea using water, methanol, ethanol and acetone as extractants
at room temperature for 3 hours under shaking condition(180rpm) with liquor
ratio(solid:solvent; 1:100). The main pigment components of tumeric root, gardenia
seeds, mugwort and green tea are known to be curcumin, crocin, chlorophyll b and epigallocatechin
gallate, respectively. The effects of the kind of extractant and pH on the
color characteristics of natural colorant extracts were investigated. The solubility parameters
of pigment components were determined to find adequate extractant. The solubility
parameters of curcumin, crocin, chlorophyll b and epigallocatechin gallate were found to
be 27.85, 29.40, 19.48 and 37.97(J/cm3)1/2. As expected, solvents that have a solubility
parameter similar to that of pigment component were generally found to be effective to
obtain pigment extracts having high visible absorbance(A). The extract(pigment/solvent)
with high visible absorbance was generally found to have low L*(lightness) and high
Chroma(C*, purity). |
