European Journal of Nutrition and Food Safety. 2025 Apr; 17(4): 216-2282347-5641https://imsear.searo.who.int/handle/123456789/248193Spray drying is an unprecedented technique in the food industry which involves conversion of liquid foods into stable powdered form, allowing enhanced transportability, solubility and stability of temperature-sensitive bioactives. It involves atomization of liquid feed into fine droplets which are rapidly dried by hot air. One of the biggest advantage of this method is its ability to preserve nutrients like vitamins, antioxidants and probiotics because of which this technique is widely applied to dairy products, fruit and vegetable powders, flavour encapsulations and nutraceuticals. For the effective encapsulation and controlled release, it is very essential to select suitable wall materials like gum Arabic and maltodextrin. Compatibility with core materials, emulsification, solubility and viscosity are some of the factors upon which the quality of products depend. Efficiency of the technique is influenced by certain parameters like air temperature, feed composition and method of atomization. Many advancements like nano and electrostatic spray drying have helped in improving precision, energy use and minimizing thermal damage. Computational modeling and real-time monitoring optimize the drying conditions. Though spray drying technology has many benefits,high energy demand and degradation of heat sensitive ingredients are few challenges which require further research and optimization.Spray dryingfood processingmaltodextrinencapsulationwall materialsJournal ArticleIndiaUniversity Institute of Agricultural Sciences, Chandigarh University, Mohali-140413, Punjab, IndiaUniversity Institute of Agricultural Sciences, Chandigarh University, Mohali-140413, Punjab, IndiaUniversity Institute of Agricultural Sciences, Chandigarh University, Mohali-140413, Punjab, India.
