Isoflavones supplementation of a probiotic soy product: effects on quality characteristics and isoflavones profile

The aim of the present study was to investigate the effect of isofl avones supplementation of a fermented soy product on its sensory acceptance, physicochemical properties and probiotic cell viable count. Additionally we also investigated the ability of the mixed starter cultures (Enterococcus faecium CRL 183 and Lactobacillus helveticus 416) to modify the isofl avones profi le of soy product during the fermentation process. Three products were analysed: soy product fermented with E. faecium CRL 183 and L. helveticus 416, isofl avonessupplemented soy product (fermented with E. faecium CRL 183 and L. helveticus 416; 50mg/100g, Isofl avin®, Galena, Brazil) and unfermented soy product. A panel of judges evaluated the acceptability of the samples on a nine point structured hedonic scale. The chemical composition namely fat, protein, ash and total carbohydrate contents, pH, enumeration of viable Lactobacillus spp. and Enterococcus spp. and quantifi cation of isofl avones using HPLC were investigated. All determinations were conducted after 7 days storage at 10°C. The sensorial acceptance was reduced in the isofl avones-supplemented soy product, but this effect was not signifi cant compared to the sample without isofl avones addition. Chemical composition did not differ (p<0.05) among the samples. Cell viable counts were reduced and total fermentation time was longer in the isofl avonessupplemented soy product, suggesting that the isofl avone addition could inhibit the starter cultures. However, all the products may be considered probiotic since they exhibited lactic acid bacterial populations varying from 2.3 x 109 up to 1.22 x 1010 CFU/mL. Fermentation of soymilk did not change the isofl avones profi le. In conclusion, it was possible to obtain a fermented soy product containing a high isofl avones concentration, adequate sensory and chemical characteristics and lactic acid bacterial viability suffi ciently high to characterize the product as a probiotic. The mixed starter culture was not able to convert the glycoside isofl avones into aglycone or produce equol during the fermented soy product processing.

A influência do contexto multimidiático na configuração atual do telejornalismo

The TV news, like other productions for television, are in the process of adaptation of its discursive structures and its production as a consequence of the structures of the digital systems. Focusing not only the formatting, but mainly on the routines, its possible to notice the emergence of a new dynamic of production and consumption of information. Interactivity is the resource that has mobilized the most effort in the adaptation of television companies, anticipating the trend towards a more strengthening receiver role in communication relationship, which should be intensified by the convergence of medias with the deployment of Brazilian digital TV. While this is not realized, producers encourage a forged approach of receivers, since the proposal is not fully enforceable, either because of limitations in the routine production or in the technological devices. Then, the enunciative strategy of interactivity seeks to renew the social bond between the TV news and its audience.

Modelagem gravimétrica no Lineamento Guapiara, sul do Estado de São Paulo

The Guapiara Lineament is an important geological feature of the State of São Paulo, Brazil, associated with Mesozoic volcanism in the Paraná Basin. This paper aims at the interpretation and modeling of gravity data collected at a semi-detailed scale between Capão Bonito and Apiaí to identify the geometry of crustal partitioning along this lineament. Maps of Bouguer anomaly in the area show a remarkable positive gravimetric anomaly oriented NW-SE, which coincides with the orientation of the greater concentration of dikes associated with the Guapiara Lineament. The crustal model developed from anomalies shows a significant thinning of the crust in the area and corroborates previous studies. The crustal thinning was caused by mantle rise, reflecting the epirogenetic activity generated by the propagation of the divergent tectonic forces that occurred at the margin of the South American Plate during the Cretaceous.
