Abstract: Yogurts from goat milk were elaborated and water-soluble soybean extract (WSSE) and Bifidobacterium lactis probiotic culture added during processing. The characteristics of apparent viscosity, water retention capacity and syneresis were analyzed during 29 days of storage and it was verified the influence of WSSE and the probiotic on these rheological properties. The suplementation of WSSE provoked an increase in the viscosity and water retention capacity of the yogurts while reducing the syneresis. The inoculation of the probiotic culture during elaboration of the yogurts did not significantly alter the rheological characteristics of the products. Therefore, the water-soluble soybean extract and the probiotic culture can contribute to the rheological characteristics of yogurts, besides the nutritional and functional improvement advantages already known with the use of these products. [Adição de extrato hidrossolúvel de soja e cultura probiótica e características de viscosidade, capacidade de retenção de água e de sinerese de iogurte produzido com leite de cabra]. Resumo: Iogurtes a base de leite de cabra foram elaborados e a eles adicionados extrato hidrossolúvel de soja (EHS) e de cultura probiótica Bifidobacterium lactis durante o processamento. As características de viscosidade aparente, capacidade de retenção de água e sinerese foram analisadas durante 29 dias de armazenamento e verificadas a influência do EHS e do probiótico nestas propriedades reológicas. A suplementação de EHS provocou aumento na viscosidade e capacidade de retenção de água dos iogurtes e, ao mesmo tempo, a sinerese foi reduzida. A inoculação da cultura probiótica durante elaboração dos iogurtes não alterou de forma significativa as características reológicas dos produtos. Portanto, a adição de extrato hidrossolúvel de soja e a cultura probiótica, pode contribuir para melhora nas características reológicas de iogurtes, além das vantagens na melhoria nutricional e funcional já conhecidas com a utilização destes produtos.

Femtosecond laser micromachining stands out as an efficient and flexible tool for fabricating optical waveguides, which are key elements in photonics for their ability to confine and direct light propagation. Different materials, from optical glasses to polymers, as well as geometries, have been studied for the fabrication of threedimensionally inscribed waveguides. This work demonstrates, for the first time, the fabrication of Type II (double-line) waveguides by fs-laser micromachining in a transparent silica xerogel bulk synthesized by the solgel process. Specifically, double-line waveguides were fabricated by the multiscan approach at approximately 200 μm below the surface, with a distance between tracks of 20 μm. It was observed fundamental, first and second-order modes of the waveguides at 632.8 nm, which were corroborated by finite elements simulation. Finally, guiding losses of about 2.9 dB/cm were observed for the fundamental mode at 632.8 nm, which is similar to results obtained for Type II waveguides for other materials. Therefore, the intrinsic features of silica xerogel (e. g. low thermal conductivity, non-toxicity, lightness, and high optical transparency) combined to its light guiding ability indicate the potential of micromachined bulk silica xerogels for photonics devices applications. |
