Ethanol concentration in ‘Bing’ cherry was found to be very
low in control and increased in CA (O2 5% + CO2 15%) storage
. Bai et al., (2011) reported ‘Lapins’ cherry
produced a minimum amount of ethanol (i.e., < 2 mg kg1) during
air storage at 1 C. In this study, ethanol was detected at 2.3 to
49 mg kg1 in ‘Lapins’ and ‘Skeena’ packed in MAP1 and 2 after 4
week storage, however, the panelists did not detect fermentative
off-flavor indicating the accumulation of ethanol in the fruit
flesh
was lower than the human sensory detection threshold. The
human olfactory detection threshold for ethanol is 100 mg kg1 in
water (Flath et al., 1967) and 64–900 mg kg1 in orange fruit
(Moshonas et al., 1991).
