Sodium cyclamate contents in the widely consumed low calorie soft drinks were determined. Low calorie soft drinks made from cola, guarana, orange, lemon and grape were analyzed following the technique described by Sjörberg and Alanko (1987), with some modifications. The methodology recovery assays were carried out at three spiked levels, and the average recovery of 92.5% and 110.3% were found in cola and guarana, respectively; and the relative standard deviation was of 3.7%. The average sodium cyclamate contents ranged from 27.1 ± 1.1 (cola A) to 127.3 ± 1.5 mg.100 mL-1 (lemon B), indicating that the acceptable daily intake of the sweetener can be easily exceeded after drinking low calorie beverages. All of the analyzed low calorie soft drinks showed sodium cyclamate contents higher than those stated on the label, ranging from 12.9% (cola A) to 19.0% (lemon B). Among 18 low calorie soft drinks analyzed, only four showed the average sodium cyclamate contents in accordance with the maximum limit permitted by Brazilian legislation, that is 40 mg.100 mL-1 of beverage; and in other samples the sweetener exceeded ranging from 74.8% (orange) to 218.3% (lemon B) above of the limit permitted.

This study aimed to evaluate the use of a mixer to determine the rheological properties of fluids. The mixer is comprised of an agitation tank and an anchor type impeller. The tests were performed with honey and fruit juices (orange, guava and peach). The rheological characterization was performed using data from the torque and rotation speed required for the operation of fluid agitation. Tests were also made with a concentric cylinder rotational viscometer with the samples being subjected to various shear rates. The rheological parameters were obtained from the flow curves fitted to the power law model. Analyses of results showed that the mixer can be used, within its limitations, to determine rheological properties.

The use of medicinal plants is common in many Brazil's ethnic groups, because the diversity of plant species in the country is large. But the utilization of these plants as standardized herbal doesn't occur with de same frequency, due the lack of studies related to these therapies, classified as alternatives. Due to the high cost of some synthetic medicines for the treatment of chronic diseases, phytotherapy is a low-cost alternative and efficient, since the phytomedication has proven scientific studies and its production meets strict criteria for manufacturing and quality control to ensure its safety and efficacy. Among the medicinal species used for the treatment of chronic diseases, such as pain and inflammation, is Eugenia speciosa Cambess, popularly known as the bush laranjinha. Against this context, this paper held preliminary studies and developed the chromatographic profile of the hydroalcoholic extract of the leaves of E. speciosa by High Performance Liquid Chromatography coupled to photodiode array detector (CLAE-DAD). Preliminary qualitative results and the chromatographic profile have identified some metabolites classes present and some constituent as: homogentisic acid, homorientina, isovitexin and quercetrin

Research on natural products is extremely important either for new compound discovery with possible pharmacology uses or for its impact on economy, which moves millions of dollars for year. Scientific studies related on utilization and characterization of bioactive substances are important due to the fact that many drugs currently used by the population were synthetized from isolated compounds of natural products. Among many medicinal species commonly used, there are that ones from the genus Eugenia, witch belongs to Myrtaceae family. Eugenia is one of the biggest genus from this family and has about 5000 species and Brazil has 400 of them, which are appreciated on gastronomy for its fruits, for example, pitanga (Eugenia uniflora), cherry (Eugenia involucrata), clove (Eugenia caryophyllata) and cagaita (Eugenia dysinterica). Phytochemical studies of plants from this genus report the presence of several secondary metabolites like flavonoids, tannins, coumarins, anthocyanins and more. Eugenia species have important pharmacology activity as antioxidant, hypothermic, antidiarrheal, antihypertensive, antimicrobial and fungicide. Thus, Eugenia is a genus which has species with potencial phytotherapic products

Diagnóstico de conflitos em áreas de preservação permanente na bacia do Rio Capivara - Botucatu (SP)
Resumo:
The permanent preservation areas (PPA) established by Brazilian law are there to protect the natural environment. With the expansion of space occupied by man and development of economic activities in these areas were engaged in conflicts characterized PPA, where the use is other than the natural vegetation. According to these paradigms work aims to raise these conflict areas in the River Basin Capivara, Botucatu (SP) with the help of GIS Ilwis 3.4, topographic maps of IBGE and satellite images CBERS 2B. The map was generated from PPA in the GIS by distance calculation in relation to drainage, springs and break line on Cuesta de Botucatu. The classes of land use and natural vegetation were determined by interpretation of satellite images and field visits to check their veracity. With the cutting of the map of land use and natural vegetation in relation to PPA unit it was determined that the total 44,63% PPA is in conflict occupied by pasture, forest plantation, orange, annual crops, farms and irrigated rice project in lowland. This diagnostic characterizes the degradation of the environment and highlights the need to harmonize the economic and urban development with the preservation of the environment to ensure sustainability of the region.

This work has the objective to elaborate the potentialities of the farming expand diagnosis of the Capivara River Hydrographic basin, in the Botucatu – SP municipal district, to obtain an interpretation of the system actual situation through the historical trajectory and possible evolution with the assistance of the SIG Ilwis 3.4 and orbital images CBERS 2B, in the pancromatics bands, obtained in 12/07/2008. The potentialities of the farming expand diagnosis was obtained through the physical mean modeling, of the farming expand presents in the studied environment and shows possible line actions to minimize the impacts e reach a sustainable development to the region. The Capivara river basin presents more than 70% of your areas occupied by the anthropic expanding, with the extensive farming predominance, forestall planting, orange and sugar cane. In the potentiality diagnostic analyses notes the good quality of the basin to the farming expand, except the region comprehended by the Botucatu Cuesta and the meadows area. The basin until has a good environmental quality and this diagnosis must serve for a start point to the realization of the territorial ordination as quick as possible to the environment conditions finds remains the same, granting the recovery capability.
