Paper Abstract

Vegetable marrows (cv. Seme Bolognese) and peach fruits (cv. Suncrest) were stored at different chilling temperatures in order to evaluate, by vibrational spectroscopy, the unsaturation degree of the total lipidic component and other possible markers of chilling injuries. Capillary Gas Chromatography also has been applied to evaluate the unsaturation degree of the esterified fatty acids. Both methodologies indicate a general increase of the unsaturation degrees with storage time. This can be interpreted as a better adaptation capability of the fruits to low temperatures. Moreover, the FTIR-ATR methodology points out the onset of a hydrolysis reaction of the esteric phosphate group of phospholipids during storage.
