| Summary: | The active modified atmosphere packaging (active MAP) system , which provides
interactive postharvest control , using ethanol vapour controlled release, is one of the current
interests in the development of active packaging for horticultural products. A number of
published research work have discussed the relationship between the effectiveness of ethanol
vapour and its concentration in the package headspace, including its effect on postharvest
decay and physiological controls. This is of importance because a controlled release system
should release and maintain ethanol vapour at effective concentrations during the desired
storage period. A balance among the mass transfer processes of ethanol vapour in the
package results in ethanol vapour accumulation in the package headspace. Key factors
affecting these processes include ethanol loading, packaging material, packaged product and
storage environment (temperature and relative h umidity). This article reviews their influences
and discusses future work required to better understand their influences on ethanol vapour
release and accumulations in active MAP.
