3. Effect of water activity and storage of tahini on the viability of stressed Salmonella serovars
Abstract Tahini (sesame seed paste) is a low water activity product that has been involved in several salmonellosis outbreaks. The objectives of the study were to examine over a year the impact of aw and storage temperature of tahini on the viability of Salmonella serovars previously stressed by drying or heat exposure. Tahini samples adjusted to aw values o

5. Does an urban environment affect leaf structure of Eugenia uniflora L. (Myrtaceae)?
ABSTRACT External factors can interfere with the structure and biological activity of plants. Nevertheless, the susceptibility of plants to specific environmental conditions varies, which raises many questions about the behavior of medicinal plants when grown in urban areas. This study aims to detect possible changes induced by exposure of Eugenia uniflora L
