mes accompanied byreductions in consumer acceptance. For example, strawberries picked at underripe stages, white or pink, have longer shelf life

and are less susceptible to damage during transporta- tion than ripe fruit. However, once exposed to ripening temperature and light,

they producenoticeably less aroma than ripe-picked berries and do not have the same taste, even thoughcolor may fully develop (.

These same authors found several quantitative and qualita-tive differences in the evolution of volatile proles of Kent strawberries over 1-dayripening

period at 1 . comprehensive study of the 3 major tomato volatiles indicated signicant differ- ences in proles due to cultivar (4 tested), degree of ripeness when picked, and storage temperature (. However, it was concluded that nal volatile production was mainlyrelated to nal ripening temperature after storage, regardless of storage temperature. Nev-ertheless, nal volatile production at full ripeness was lower in all instances than in thosepicked table-ripe. Volatile Monitoring in Storage 5 Controlled atmospheres (CAs) of various gas compositions and temperatures are used in the long-term storage of various commodities. Since the main inuence of CAstorage is to reduce metabolic activity to minimum by reducing the availability of 2, production of volatiles, including respiratory CO 2, is usually lower than for the same commodity stored at the same temperature in regular atmospheres. The same is true for hypobaric storage. On the other hand, study of McIntosh and Cortland apples ( indicated increases in the production of certain volatiles under low-ethylene controlledatmosphere (LCA) storage (3% 2,3 % compared to storage in air at the same temperature (3.3 ), and that Cortland apples produce the same amount of total volatiles under LCA as in air. Although storage and shelf lives of many fruits were substantially increased by technologies such as CA, LCA, and hypobaric storage, the observation that the fr
