The paper investigates the use of poly(1-vinylpyrrolidone-co-2-dimethylaminoethylmetacrilate) (PVP-co-DMAEMA) as a novel coating agent in the preparation of alginate-based microcapsule for the supplement delivery of probiotics. Probiotic Lactobacillus plantarum is used to study the viability of the encapsulated bacterium when exposed to conditions simulating the gastrointestinal tract and industrial process. Results demonstrate that the PVP-co-DMAEMA polymer constitutes a pH-responsive coating suitable for probiotic supplement delivery.
