Lf. Di Cesare et al., Volatile fraction and chemical-physical parameters in some Italian blueberry cultivars during low temperature storage, IND ALI, 39(394), 2000, pp. 835
Three blueberry cultivars grown in Italy (Blueray, Bluetta and Concord) wer
e stored at -20 degrees C for 6 and 9 months. The cultivars were submitted
to the analysis of the volatile compounds and some chemical-physical parame
ters. The GUMS analysis of the volatile fractions pointed out that the perc
entage compositions of alcohols and aldehydes, responsible for the "green-f
ruity" note, decreased more remarkably than the terpenic compounds, respons
ible for the "floreal-woody" note. Linalool increased during the first six
months. Among the chemical-physical parameters, only the anthocyanic substa
nces decreased during the storage.
