The response surface methodology was employed to optimize the microencapsulation condition of cold‐pressed winter squash ( Cucurbita moschata Duchesne) seed oil. The powder yield, extraction efficiency, and bulk density were investigated with respect to two factors including concentration of maltodextrin DE 10 (5, 10, and 15% w/w) combined with 10% w/w gum Arabic to coating wall and inlet air temperature (140, 160, and 180°C). The predicted conditions to simultaneously provide the maximum possible yield and encapsulation efficiency were: inlet temperature 172°C and maltodextrin content 15% w/w. Under such conditions, powder yield was estimated to be 63.2% w/w, 77.4% encapsulation efficiency, 4.4% w/w moisture content, and 0.284 g/ml bulk density. The results here obtained demonstrate the potential represented by this species as an alternative for the vegetable oil industry as food ingredient and nutrition supplement. Practical applications Unsaturated fatty acids and other bioactive compounds are highly susceptible to oxidation when exposed to oxygen, light, moisture, and temperature. As response to these problems, feasibility of microencapsulating cold‐pressed winter squash seed oil by spray drying was investigated in this work. A method for optimizing microencapsulation conditions of winter squash seed oil by using response surface methodology was studied. This research may be useful for identifying the most appropriate operating conditions for winter squash seed oil microencapsulation for industrial application, especially in food and pharmaceutical industries, as well as for reference for further investigative works.
