These findings indicate the efficiency in associating WPI and FOS for probiotics encapsulation. It is in conformity with previous study which reported higher survival rates for the encapsulation of L. plantarum when using WPI coupled with FOS as coating material [9]. WPI, on its account, has been proved to exert excellentprotectivecapacity.Indeed,justlikethegelatin,WPI isabletoformgelsinthefavorableconditionswhichissuitable fortheformationandsolidificationofthewallmaterial.Ainsley Reidetal.[8]reportedthattheprocessofmicroencapsulationin WPImicrospherescanhelpinprotectingthefreeze-driedcells against subsequent conditions such as freezing of food products.Hence,WPIusedalonewerenotasefficientaswhenused combinedwithFOS,therefore,ourresultssuggestthattheprotectiveeffectprovidedbymicrospheres(WPI+FOS)isaswell due to the adjunction of FOS.
