Abstract
Summary: Properties of flexible film liners and valves used in wine casks were studied to assess their influence on the loss in quality of wine retailed locally in this type of package.Oxygen permeability measurements were made at 25°C and 75% r.h. on two types of liner materials and three types of valves. A procedure involving treatment of the valve sealing surfaces with polydimethyl siloxane was developed to test valves under simulated conditions of use. Application of these results to an analytical model of a wine pack suggested that the rate of oxygen uptake by wine may be as high as 0.17 ppm/day and that the valves contributed 33–52% of this amount.Theoretical considerations demonstrate that loss of SO2 from the model by permeation was negligible.Keywords
