Description
An aqueous extract from the tuberous roots of Decalepis hamiltonii was encapsulated by spray-drying and freeze-drying for food applications. The study aimed to identify suitable carrier materials among sodium caseinate, maltodextrin, and gum acacia, used alone and in blends, to understand their collective effect during encapsulation. The physicochemical characteristics of freeze-dried and spray-dried samples revealed differences of 14%20% in 2-hydroxy-4-methoxy benzaldehyde, 12%40% in phenolic content, and 7%40% in flavonoid content in the dried powders. Similarly, the methanol extracts of freeze-dried encapsulated samples demonstrated good antioxidant potential compared with those of spray-dried encapsulated powder. Among the carrier materials used, sodium caseinate showed good retention of bioactives and a flavor metabolite (2-hydroxy-4-methoxybenzaldehyde), which was quantified by high-performance liquid chromatography (encapsulation efficiency 82%; yield 40 w/w) and confirmed by1H nuclear magnetic resonance (NMR). However, in this study considering flavor retention and powder yield (encapsulation efficiency 74% and 59 w/w), maltodextrin in combination with sodium caseinate (MS) was observed to be the best carrier material for spray-drying. These "maltodextrinsodium caseinate" microcapsules are stable and show 70% retention of flavor metabolite after 3 months of storage at room temperature, with the microbial load remaining within acceptable limits. The particle size of the carrier materials ranges from 11.1 to 17.6 m. Thus, the current study suggests that a carrier material mixture (sodium caseinate and maltodextrin) can be used as a prospective material for encapsulating Decalepis hamiltonii bioactives with flavor metabolites and may be useful in food formulations. 2025 by the author(s).
