Abstract

This study aims to determine the effect of variations in drying temperature and concentration of green spinach juice (Amaranthus hybridus l) on spinach milk powder using a rotary vacuum machine. This study uses the research design method used is a factorial randomized block design with 2 repetitions. The treatment design carried out in this study consisted of two factors, namely the drying temperature (T) consisting of 3 levels. The rotary vacuum drying method produces the best characteristics with a moisture content of 2.21%, chlorophyll content of 7.65 mg/l, antioxidant activity of 2024.22 ppm. The results of the best physical analysis were 31.50 seconds of dissolution time, 14.95% yield, 80.18% solubility, 11.35% hygroscopicity, 18.11 Cp viscosity, color intensity L* 63.21, color -a* 7, 00, color b* 26.68.
