This article reports the results of a study that aimed at evaluating the effects of aging technique on cachaça samples produced and sold by small farmers in São Paulo State, Brazil. Cachaças, aged and not aged were sent by 10 cachaça producers that take part in the community project and course: São Paulo State Contest of Distillery Cachaça and Production Chain of Cachaça Meeting, organized by the Food and Nutrition Department of Pharmaceutical Sciences University, UNESP/Araraquara, SP, Brazil, in partnership with the Brazilian Service of Support to Micro and Small Enterprise of São Paulo State (SEBRAE-SP) and the Rural Union of Araraquara. The evaluation of the samples was made based on sensory tests conducted in Analysis and Quality Control of Foods and Drinks Laboratory of the Department. The survey results showed significantly higher acceptance average in the aged samples compared with not aged ones. The aging process, which was one of the topics discussed in the course, was considered as an effective way to improve the quality of cachaça, the research also confirmed the importance of the University support to improve the quality of food and drink produced in Brazil.

The Current work to assess the capacity of water potability samples for that, we used seven different brands of mineral water, bought locally, and also collected seven samples of public drinking fountains located in different places on campus headquarters of the State University of Maringá. The parameters analyzed were presence of fecal and total coliform, turbidity, color and compounds with UV-absorption at 254 nm. On the analysis of coliforms, two brands of mineral water and four samples of drinkers showed presence of total coliform, but no analysis indicated the presence of fecal coliforms. In the turbidity parameter, all samples were within the limits allowed by law, for both cases. No apparent color attribute, two samples of mineral water and a sample of drinking were outside the range required by law. Finally, the determination of UV showed the values of light absorption of each sample at a wavelength of 254nm, however, does not yet exist in Brazil a regulation on this parameter. With such analysis, it was possible to compare the results with current legislation. After these findings, it appears that more stringent hygienic practices should be adopted throughout the processing of mineral water as drinking in public. It is also necessary for greater oversight over the other parameters for determining the quality of water.
