- Abstract
The flavour compounds of fresh and freeze-dried banana slices were concentrated by solvent extraction and investigated by gas chromatography/mass spectrometry. While many compounds show good retention in the starchy matrix, the highly volatile carboxylic esters show losses from 50 to 80%. Compensating for the losses of the isopentyl esters - compounds of special sensory importance - bananas were submitted to the biotechnological process of PA (=precursor atmosphere) - storage prior to dehydration. A considerable flavour accumulation in the fruit tissue is achieved by using natural metabolic pathways. As a result a quality improved dry product - containing a similar amount of isopentyl esters as the fresh fruit - is obtained.
