Abstract

Miana (Coleus scutellaroides) is an ornamental plant of single leaf a purple color. The purple color found from miana leaves is an indicator of the presence of anthocyanin pigments. Anthocyanin from miana leaves can be utilized as a natural pigment for various staining purposes especially in the food industry, anthocyanin harvesting on miana leaves can be done at any time and does not depend on the season due to its abundant availability in nature.The aims of this study were to isolate, identify, and microencapsulated anthocyanin pigments of miana leaves. The result, pigment extracted from miana leaves had characteristic of purple color and having maximum absorbance at wavelength 529 nm, suspected as anthocyanin derivative (cyanidin-3-routosida).The total microcapsulated anthocyanim was 0.149542 mg / g. Thermostability of encapsulated anthocyanin pigment from miana leaves stable with heat exposure temperature 100C up to 60 minutes. Based on those collected information, encapsulated miana leaves pigment could be used as an additional natural coloring in food industries.
