The present study was conducted to optimize the operational conditions for development of spray‐dried ginger oleoresin powder by using response surface methodology (RSM). The carrier agent concentration (15–35%), gingerol concentration (10%–30%), inlet temperature (155–175°C), and feed flow rate (300–500 ml/hr) were kept as independent variables. While the responses analyzed for deciding the optimum operational conditions were moisture content, product yield, hygroscopicity, rehydration ratio, and total oleoresin content, respectively. Although experimental values and the predicted ones exhibited small deviations, but the values were within the acceptable limits. Results showed the most desirable optimum condition for ginger oleoresin powder were gum acacia and whey protein isolate (30%), gingerol concentration (23% and 25%), inlet temperature (170°C), and feed flow rate (350 ml/hr), respectively, for obtaining powder with desired characteristics such as low moisture content, increased yield, low hygroscopicity, high rehydration ratio, and high oleoresin content. Practical applications Gingerols prepared by various solvent extraction methods consists of volatile oil, nonvolatile fatty and resinous material, and other active ingredients. They possess number of health beneficial effects such as antitumor, antioxidant, antimicrobial, and anti‐inflammatory properties. The microencapsulation of ginger oleoresin helps to reduce oxidation process by exposure to the environment, increasing the shelf life and the solubility. Oleoresin microcapsule can also be used as a therapeutic agent.
