Green (Detox) juice physicochemical properties and stabilization effect of naturals emulsifiers Ciência Rural
Fraga,Jully Lacerda; Sant’Ana,Gizele Cardoso Fontes; Silva,Kelly Alencar; Amaral,Priscilla Filomena Fonseca.
ABSTRACT: Green or “detox” juice is a mixture of fruit juice with vegetables, which has been used intensively by consumers seeking for healthy food. Physicochemical properties of Green juice were accessed in the present research, which brings new insights for the use of this beverage in human diet. A total phenolic content of 2833.60 mg GAE (Gallic acid equivalent)/ g of juice and a Total Antioxidant Capacity by FRAP of 323.62 µM Fe2SO4 / g of juice and by ABTS•+ of 333.11 µM Trolox/ g of juice, indicated good antioxidant properties. Low energy and reducing sugar content indicate its use for low calorie diet, but low carbohydrate and protein content prove that Green juice cannot be used as meal replacement. The addition of a microbial biosurfactant (YlBio)...

Petroleum-derived hydrocarbons are among the most persistent soil contaminants, and some hydrocarbon-degrading microorganisms can produce biosurfactants to increase bioavailability and degradation. The aim of this work was to identify biosurfactant-producing bacterial strains isolated from hydrocarbon-contaminated sites, and to evaluate their biosurfactant properties. The drop-collapse method and minimal agar added with a layer of combustoleo were used for screening, and positive strains were grown in liquid medium, and surface tension and emulsification index were determined in cell-free supernantant and cell suspension. A total of 324 bacterial strains were tested, and 17 were positive for the drop-collapse and hydrocarbon-layer agar methods. Most of the...
