Innovation of synthetic dyes successfully eliminated the utilisation of natural materials as textile dyes. Simplicity as well as variety of colours strongly increased the application of synthetic dyes. Nevertheless, environmental concern has lately forced the use of natural dyes. To simplify the usage of natural dyes, production of natural dyes powder is inevitable. Investigation was carried out to examine the effects of solvent and filler types on the yield, chromaticity, flavonoid content, and water content of natural dyes powder. In this work, Brachiaria mutica was used as a sample source. It was crushed and grinded before extracted using mixture of methanol and water as solvents at various methanol concentration of 25%, 50%, 75%, and 100%. Extraction was carried out at a ratio of raw materials to solvent of 1:10. The filler of maltodextrine or gum arabic was added into dye extract before then converted into powder form by the aid of spray dryer. It was found that among the provided.....
