Partition coefficients are then linked to quantitative measurements to {obtain|acquire|get|receive} partial pressures, which describes the availability of volatile compounds {in the|within the|inside the} gas phase. The {concept|idea|notion} of partition coefficients and partial {pressure|stress} have then been applied to a time series of aroma {changes|modifications|adjustments|alterations} {due to|because of|as a result of|on account of|resulting from|as a consequence of} oxidation in {commercial|industrial} wines.
