Probiotic orange Bacillus‐infused jelly candies: development and effect on food borne, oral pathogen and commercial probiotics

Summary This research presents a novel approach to develop pigmented probiotic jelly candies by incorporating an orange pigment‐producing Bacillus 63‐11 strain, encapsulated with surface maltodextrin (MDs) or internal coating maltodextrin (MDi) or sodium alginate (SA). The study evaluated the impact of different coating methods on probiotic activities, antagonistic effects, physical properties and consumer acceptance. Results indicated that coating methods did not compromise the probiotic and antagonistic properties of the Bacillus 63‐11 strain. Over a 6‐month period, all coating methods exhibited increased water activity with minimal microbiological changes. MD‐coated candies demonstrated optimal probiotic viability, tolerance and sensory appeal, emphasising colour preferences. SA‐coated candies exhibited lower viability but superior texture. This study demonstrated the successful development of an unconventional jelly candy prototype with implications for commercialisation. The findings underscore the pivotal role of coating material and method in influencing crucial aspects of the candy, offering valuable insights for the market potential of such innovative products.
