Abstract: (1)Resumo -A utilização de proteínas sarcoplasmáticas junto de proteínas miofibrilares pode ser interessante na tecnologia de filmes comestíveis, pois eliminaria o processo de lavagem do músculo no preparo das proteínas. O objetivo deste trabalho foi estudar propriedades físicas de filmes constituídos de proteínas miofibrilares e sarcoplasmáticas do musculo de tilápia-do-nilo (Oreochromis niloticus), em razão da concentração de proteínas e do plastificante na solução filmogênica. Os filmes foram elaborados a p… Show more

“…After drying, the films were carefully removed from plates and placed in desiccators (NaBr saline saturated solution, relative humidity = 58%) at 25 °C for at least 48 h until analysis. The thickness of each strips was measured using digital micrometer (Mitutoyo), considering the average of at least nine values [13] . The overall aspects of the product were evaluated, considering its homogeneity, easiness of peeling from acrylic plate and presence of bubbles or grumps.…”

“…A diferença de cor (ΔE) (Figura 1a e 2b), o que pode ser explicada pela cor amarelada característica da matéria-prima. Este fato também foi observado por Sobral et al [23] em filmes de proteínas miofibrilares e sarcoplasmáticas de tilápia-donilo, verificando maior coloração desses filmes com adição de maior teor de proteínas. Os materiais do presente trabalho apresentaram coloração mais acentuada do que os filmes elaborados com proteína miofibrilar de tilápia-do-nilo (ΔE entre 7,0 e 8,0) [24] .…”

“…The a* value describes the amount of redness (positive) or greenness (negative), and the b* value describes the amount of yellowness (positive) or blueness (negative) present in the specimen. The combination of the values of a* and b* define the hue and intensity (saturation) of the color . The L* , a* , and b* values of each film were taken as the average of at least five points.…”
