Název v původním jazyce

Influence of storage and infection with Gloeosporium album Osterw. on release of volatile compounds from different apple cultivars

Popis výsledku v původním jazyce

Release of volatile compounds from intact, sound fruit into the surrounding atmosphere was minimal. The predominant compound was butylacetate, but with differences between the five cultivars studied ('Colden Delicious', 'Idareď, 'Jonagoreď, 'King Jonagolď and 'Meteor'). The production of acetaldehyde, ethanol and ethylacetate after 30 days of cold storage was very low. Nineteen volatile compounds were detected for the cultivar 'Meteor' 30 days after harvest. Predominant compounds trapped in a column were esters such as butylacetate (46.7micro/g/kg.h), 2-methylbutylacetate (77.7 micro/g/kg.h) and hexylacetate (30.4 micro/g/kg.h) and conferred a characteristic 'apple' odour. Other compounds, at lower levels, ranged from 0.1 micro/g/kg.h for hexylhexanoate to 5.0 micro/g/kg.h for 2-methylbutan-l-ol. Using discrimination analysis one could identify the different apple cultivars and determine whether they were infected with Gloeosporium album or not. This offers a new method for monitoring
