Flavour Stability of a Cold-Stored Unpasteurized Low-Alcohol Beer Produced by Saccharomycodes ludwigii

Stability of Unpasteurized and Refrigerated Orange Juice

The stability of orange juice obtained from a small extractor and stored in a polyethylene bottle was assessed under isothermal and non-isothermal storage conditions at 4, 8 and 12C for 72 hours. pH, titratable acidity and Brix did not alter significantly during the 72 hours storage. Microbiological analysis showed high initial count for moulds and yeasts that increased in the juice stored for ...

Use of Non-Saccharomyces Yeasts in Bottle Fermentation of Aged Beers

Bottle fermented and brewed beers are reaching more recognition in present days due to their high sensory complexity. These beers normally are produced by an initial tank fermentation to metabolize the sugars obtaining the typical alcoholic degree, and later the foam and CO2 pressure is produced by subsequent bottle fermentation. The sensory profile is improved by the formation of some fermenta...

Hot and Cold Tensile Behavior of Al 6061 Produced by Equal Channel Angular Pressing and Subsequent Cold Rolling

The full annealing AA6061 aluminum alloy was subjected to severe plastic deformationvia the combination of equal channel angular pressing (ECAP) and cold rolling (CR) in order torefine its microstructure and to improve its mechanical properties. According to the results of hotand cold tensile tests, the combination of ECAP and CR significantly affected the final strengthand ductility of studied...

Detection of Cold Agglutinin with Cross-Reactive Idiotype Produced by Pneumonie Patients

Increased calcium permeability of cold-stored erythrocytes.

The calcium, sodium, and magnesium permeability of erythrocytes from blood stored at 4 degrees C in various anticoagulant media has been studied and compared to that of fresh erythrocytes. Passive influx of CA2+ was measured at 37 degrees C in cells pretreated to abolish Ca2+ pumping and was up to fivefold greater for cold-stored erythrocytes than for fresh cells. The Ca2+ leakiness developed g...
