The aim of our research was to elaborate, characterize and evaluate the stability under light/darkness different temperatures (4 25 ºC) color an isotonic beverage based on whey permeate with carotenoid extract powder from pequi, verify its microbiological safety sensory acceptance. 3% (w/v) concentration powdered pequi chosen because it has osmolality (314.89 mOsmol/L) in range hydroelectrolyti...

Anaerobic Membrane Bioreactor technology has great advantages for treating wastewater, including energy recovery from organic matter. However, when the legislation requires that effluent standards be met in sensitive areas, this treatment cannot remove nutrients, thus permeate generated needs post-treatment. Apart biological processes, ion exchange is an alternative stream since it can nutrient...

A graphene oxide (GO) membrane is supported on a ceramic hollow fiber prepared by a vacuum suction method. This GO membrane exhibited excellent water permeation for dimethyl carbonate/water mixtures through a pervaporation process. At 25 °C and 2.6 wt % feed water content, the permeate water content reached 95.2 wt% with a high permeation flux (1702 g m(-2) h(-1)).

An oxime containing fluorescent probe based on a BODIPY scaffold was successfully designed and used for HClO determination with rapid response, low detection limits and high selectivity. Confocal fluorescence microscopy demonstrated that the probe could permeate the mitochondria and made possible the fast fluorescent imaging of endogenous HClO.

The dairy industry uses enzymes to make cheese, alter product flavor, and eliminate lactose. activities of these have been measured in clear buffered solutions, but because the limitations spectrophotometric methods, enzyme not opaque or colored products where they are used. Isothermal titration calorimetry (ITC) can be used determine reaction kinetics solutions by measuring heat rate (thermal ...

High liquid entry pressure (LEP) is one of the desired characteristics of a membrane distillation (MD) membrane. Maintaining LEP above operating feed pressure conditions is critical to prevent permeate quality worsening by saline feed liquid passage through the membrane. Air gap membrane distillation experiments under controlled salinity and temperature operating conditions indicate that in add...
