Abstract

Abstract In the present study, encapsulated strain Lactiplantibacillus rhamnosus NCDC 347 was used to prepare a novel whey protein–based beverage. The encapsulation process utilized skimmed milk powder matrix and evaluated strain viability, physico-chemical properties, sensory assessment, and shelf-life stability. Encapsulated L. rhamnosus NCDC 347 within skim milk powder maintained viability at 8.0 log CFU/g, forming spherical microcapsules with 1–12 µm concavities. Probiotic addition to whey protein beverages maintained pH and acidity within desired ranges. Physico-chemical analysis showed protein content of 8.71 ± 0.21 % to 10.05 ± 0.42 %, fat content of 0.56 ± 0.24 % to 0.67 ± 0.13 %, viscosity of 5.14 pa/s, and total soluble solids (TSS) of 14.42 ± 0.31 to 16.16 ± 0.23° Brix. The shelf-life study revealed that the beverage remained stable for up to 90 days with no significant changes (p > 0.05) in sensory analysis. The sensory analysis scored the test sample’s acceptability at 7.3 ± 0.41. The protein-rich probiotic drink exhibited favorable sensory qualities. Overall, incorporating encapsulated probiotic strain L. rhamnosus NCDC 347 into whey protein beverages could address daily protein requirements and enhance health.
