Zinc (Zn) is important in maintaining metabolic condition of human health and its deficiency increases the prevalence of diarrhea especially in children. Novel Zn fortificants such as carbohydrate/protein-Zn chelates, nano-Zn oxides, etc., enhance the solubility of Zn under various processing conditions. In the present study, the conditions for the production of spray dried whey protein concentrate-Zn complex (WP-Zn) were optimized using combinations of variables like inlet air temperature, feed flow rate and total solids and responses like moisture, yield and solubility by adopting Central Composite Response Design (CCRD). The models for moisture, solubility and yield were statistically significant. Optimized conditions comprised of 200 degrees C inlet temperature, 3 mL/min flow rate and 14.4% total solids. Milk fortified with WP-Zn (@35 ppm Zn) showed similar sensory acceptability with control (unfortified milk). Physicochemical properties (pH, acidity and viscosity) of fortified milk showed non-significant differences with control.
