Maillard conjugates of whey protein isolate–xylooligosaccharides for the microencapsulation of Lactobacillus rhamnosus: protective effects and stability during spray drying, storage and gastrointestinal digestion

The Maillard reaction products (MRPs) of whey protein isolate (WPI) and xylooligosaccharides (XOS) were prepared by a moist heat method for use as protectants to encapsulate Lactobacillus rhamnosus via spray drying.
