Spray drying is widely used for powder production from liquid concentrates. Often low input temperatures are desired, as many materials, like proteins, are sensitive to heat. However, this demand leads to increased concentrate viscosities. Commonly used pressure swirl atomizers are limited concerning maximum processible viscosity. In this study, a so called Air-Core-Liquid-Ring Atomizer is used for pilot scale spray drying of whey protein concentrate (WPC80) at 40 °C and hence a viscosity of 0.09 Pa s. The produced powder was compared to an industrially produced reference. As a result, no significant differences in particle size distribution and particle morphology were observed. Keywords: spray drying, atomization, ACLR, high viscous feeds, whey protein concentrate.

Roselle (Hibiscus sabdariffa) was a member of Malvaceae family. Its calyxes had bright red color due to presence of anthocyanin with an excellent antioxidant property. Raw roselle (Hibiscus sabdariffa L.) calyx was highly perishable due to its high moisture content. In order to diversify products from this plant, this research evaluated the possibility of spray drying for roselle extract into dried powder for long-term consumption. We focused on the effect of sugar alcohols (mannitol, sorbitol, isomalt, xylitol, erythritol) at 8%, carrier agents (maltodextrin, gum arabic, glutinous starch, whey protein concentrate, carboxymethyl cellulose) at 12%, operating parameters of spray dryer (inlet/outlet air temperature, feed rate) on physicochemical quality (bulk density, solubility, total phenolic content, total flavonoid content, anthocyanin content) of rosselle powder. Results showed that the optimal spray drying variables for rosselle powder should be 8% isomalt, 12% whey protein concentrate, inlet/ outlet air temperature 140/85oC/oC, feed rate 12 ml/min. Based on these optimal conditions, the highest physicochemical attributes of the dried roselle calyx powder would be obtained.
