In this study the potential of cloud point extraction formed by a non-ionic surfactant was used in order to separate polyphenols from industrial residues of camu-camu. The effects of operational conditions of the cloud point extraction(CPE) on the polyphenol recovery and volumetric ratio were investigated. The results showed a maximum recovery of 95.71% that was obtained using 7.0 wt% Triton X-114, native pH(3.25), and 80 wt%polyphenol extract at 30 °C. The use of cloud point extraction was successful to recover the polyphenols from agroindustrial residue since it is a simple as well as of low-cost technique.

Brazilian Sugar in Domestic Retail: The Quality of Sugar Consumed in the State of Sao Paulo

引用

Natural Science 2016年第3期8卷 160-169页

作者： Anna Flavia de souza silva Sandra Helena da Cruz Escola Superior de Agricultura Luiz de Queiroz Universidade de Sao Paulo Piracicaba Brazil

Brazil is the largest producer of sugarcane and its derivatives in the world, and one of the largest consumers of sugarcane derivatives. Sugar places a position of great prominence in Brazilian feed, either by direct consumption or as a component of industrialized products, from increasing consumption in the country. Sugar samples taken from local market were analyzed as the quality of table sugar consumed in the state of Sao Paulo (Brazil). The analysis of the parameters and basic attributes of characterization of sugar was according to the methodology developed by ICUMSA (2005;2011) and ICUMSA modified by Copersucar (2002). Samples of sugar from this region showed that medium-low quality. It can be observed in fundamental aspects such as purity and insoluble residues, which were below the standard. In addition, it should be noted the difficulty of obtaining information about the limit values for each attribute, by virtue of Legislation not be assertive to the product and, also, the scientific studies have not been unified to present the specifics for each type of sugar.

Background: IgG4-related disease is a rare autoimmune condition that presents with lymphoplasmacytic infiltrate and fibrosis in the organ affected. Isolated testicle involvement is uncommon and there are only a few cases reported in the literature. Case Presentation: We report a case of isolated chronic orchitis due to IgG4 hypersecretion in a 61-year-old patient that evolved with asymptomatic tumor-like mass growth and was treated with left orchiectomy. Histopathological study revealed orchitis related to IgG4 hypersecretion disease. Conclusion: IgG4-related disease can be manifested as a multi or single-organ disorder. Most diagnoses are made after surgery with histopathological analysis. Most of the cases in literature stand out the difficulty in diagnosis and necessity of high suspicion due to this condition’s similarity with neoplasm presentation.
