Abstract
Cannabidiol (CBD)-infused bottled water has recently become one of the new types of functional beverages in the expanding cannabinoid and nutraceutical market. This paper presents preliminary experimental observations combined with a literature-based analysis to investigate quality and stability parameters of CBD-infused bottled water. Physicochemical characterization, microbial quality analysis and stability monitoring of CBD under storage conditions were included in the experimental work. The results indicated that the formulation maintained the properties of its initial dispersion during the first period of storage. An increase in transparency and a decrease in CBD concentration were noted. Microbial counts increased during storage, suggesting that microbiological stability is limited by time under the tested conditions. Reviewing the literature underlines the significance of cannabinoid stability in aqueous beverages aided by nanoemulsion delivery systems, packaging materials and controlled storage environments. The results show that CBD can be infused into bottled water but challenges regarding formulation and storage exist. The research was not conducted to address long shelf-life, commercial scalability or compliance with regulations but to provide primary information on quality and stability factors influencing CBD beverages. More research using standardized procedures is required to understand safety, efficacy and stability over time.
