  • We analyzed the physicochemical properties, quality properties and thermodynamic functions of the passion fruit juice microencapsulated by spray drying.

  • The influence of temperature, moisture content and water activity play an important role on vitamin C retention of passion fruit juice microencapsulated.

  • Factors such as the type of wall material, composition and diffusion for porosity in the structure of the wall material can explain like affect the stability of the microcapsules.

  • The thermodynamic analysis of sorption isotherms allowed determination of the best storage conditions for providing long-term physical stability to passion fruit juice microencapsulated.

  • The passion fruit juice microencapsulated can be used to industrial applications (i.e., instant beverage) and served as a source of vitamin C.
