The encapsulant matrix formulation containing DGS [HWP (or WPI)–DGS–RS–oil matrix] provided better probiotic protection during storage compared to the formulation containing glucose [HWP–Glucose–RS–oil matrix]. SD LGG formulations with HWP (or WPI)–DGS–RS–oil matrix had the highest % survival (~2 log10 loss, equivalent to commercial FD LGG), while also maintaining the physical characteristics (e.g. colour, powder flow properties) of the microencapsulated probiotic powder, after 12 months' non-refrigerated storage in aluminium foil packaging.
