A process to concentrate aqueous coffee extract by freeze concentration is proposed to achieve an industrially viable system. The techniques of falling film freeze concentration, fractionated thawing and block freeze ...

The progressive freeze concentration of sucrose solutions was tested. The effect of the initial concentration of the solution (C0), the temperature of the refrigerant (T), and the stirring speed (ω) on the final concentration ...

The retention of solutes in the ice formed in a falling-film freeze concentrator (multi-plate freeze-concentrator) was analysed. Solutions of fructose, glucose and sucrose and a simulated juice with initial concentrations ...

To date, sunlight driven photocatalytic process for wastewater treatment is a great challenge. Herein, the photocatalytic methylene blue (MB) dye degradation activity of silver vanadate nanobelts has been enhanced using ...

The local critical coalescence concentration l-CCC presents a relationship between frother concentration and the gas flow rate Q(g)' at which coalescence starts to occur at a capillary tube. Such a relationship is used in ...

The rise in boiling point of coffee extract was experimentally measured at soluble solids concentrations in the range of 9.2 to 52.4°Brix and pressures between 5.8 × 103 and 9.4 × 104 Pa (abs.). Different approaches to ...

Background: Many methods are available for the concentration of proteins; however, most are not easily scalable due to costs, the need of specialized instruments and skilled workers or are very time-consuming. Three-phase ...
