In this work, a study on the occurrence and behavior of illicit drugs and metabolites in sewage water systems has been made. A comprehensive dataset was obtained by analyzing illicit drugs daily in influent and effluent waters from three sewage treatment
The aim of this study was to make lemon marmalades in which sucrose is replaced by sweeteners such as tagatose and isomaltulose. Analyses of Brix, pH, moisture, water activity, antioxidant capacity, optical and rheological properties were carried out on marmalades on their first day of storage, and after 60 days of storage. Microbiological analyses were also performed. Moreover, a sensory evaluation was performed to assess its consumer acceptance as compared to marmalade made with sucrose. The results showed that the antioxidant capacity of the new formulations was lower than in marmalade with sucrose. Moreover, marmalades made with healthy sweeteners showed lower consistency than those made with sucrose. Lemon marmalades formulated with a higher proportion of isomaltulose initially had high luminosity compared to the other samples, but browned over time. All marmalades were microbiologically stable, and the marmalades made with healthy sweeteners were scored better than those made with sucrose.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
