Freeze desalination by the integration of falling film and block freeze-concentration techniques

Volatile compounds, sensory quality and ice morphology in falling-film and block freeze concentration of coffee extract

Coffee extract was freeze-concentrated through block and falling-film techniques. Solute retention and concentration efficiency were determined after one stage of these processes. Ice morphology was characterized through image analysis. Preservation of volatile compounds was determined through GC-MS. The effect of coffee extract on flavour was determined after freeze concentration through senso...

Evaluation of the performance of a new freeze desalination technology

The use of desalination technologies which produce concentrated brines is acutely limited by inadequate waste brine disposal mechanisms such that the brine does not contaminate fresh water resources. The treatment of highly saline brine using freeze desalination technique trade marked as HybridICE technology was investigated at pilot scale. The capacity of the HybridICE process to generate fres...

Envelope of mouse mammary tumor virus studied by freeze-etching and freeze-fracture techniques.

As part of a study of the cell surface changes associated with the production of murine mammary tumor virus, the structure of the envelope of this virus has been examined by using freeze-fracture techniques. Both fracture and deep-etch surfaces were examined. The fracture faces contain 10-nm spheres comparable to those observed on fractured plasma membranes, although fewer in number. Surfaces e...

Task 2.6: Mechanical Freeze/Thaw and Freeze Concentration of Water and Wastewater Residuals

The Impact of the Block Freeze Concentration Process on Human Milk Properties Intended for Feeding Newborns

Human milk is the ideal nutritional support for premature neonates. Considering the need for aggregating nutritional value to human milk provided to such vulnerable group of infants, human milk was concentrated by the block freeze concentration technique. The effects of freeze concentration on the physicochemical properties, the efficiency of the process, color parameters, and the density and d...
