Abstract:

The aroma components of fresh, vacuum-dried and further explosion-puffed banana slices were analyzed and
compared by solid phase micro-extraction (SPME) coupled with gas chromatography-mass spectrometry (GC-MS). The
varieties and amounts of aroma components in the three banana samples were quite different. The explosion puffing drying
at modified temperature and pressure reduced the content of esters in banana, but at the same time generated a series of
unique aroma components.

Key words: bananas, aroma components, solid phase micro-extraction-gas chromatography-mass spectrometry, explosion puffing drying at variable temperature and pressure
