Resumen
A method for collection and 3-minute analysis of internal gas samples of citrus fruit is described in detail, including the handling of samples and analysis by gas chromatography with molecular sieve columns. A new method is presented for correcting internal O[sub2] concentrations of citrus fruit and apples for argon content. An internal-gas method is described for determining the barrier properties of fruit peel to movement of gases, including ethane and ethylene. Internal gas volume of fruit was measured by dilution of internal gases.
