Volatile Oxidation Compounds and Stability of Safflower, Sesame and Canola Cold-Pressed Oils as Affected by Thermal and Microwave Treatments

“…The other identified ketone was 3,5-octadien- 2-one which present only in canola oil and its content increased in the oxidized oil during storage. The similar increase trend for canola oil with oxidation was observed in the results of Mildner-Szkudlarz et al 32 . 3-octen-2-one and 2-heptanone were found as ketones only in safflower oil at the late of thermal oxidation at 60 .…”

“…Besides, this compound was appeared in safflower oil and the content of this compound reached up to the highest level among oils during storage. E,E -2,4-decadienal was detected in the oxidized oils olive, soybean, sunflower, peanut and rapeseed oils and its content increased in the oils stored for 5 days at 60 32 . The note was peculiar to cold-pressed oils and this sensory situation of these oils could be related to the presence of 2,4-decadienal or hexanal 33,34 .…”

Characterization of Volatile Compounds with HS-SPME from Oxidized n-3 PUFA Rich Oils via Rancimat Tests

“…Chemometric techniques were used to discriminate the experimental data to determine which detected volatile compounds were suitable as marker substances 30,31 .…”

Prospects of fatty acid profile and bioactive composition from lipid seeds for the discrimination of apple varieties with the application of chemometrics

“…5). The major group contained the Royal Gala, Red Delicious, and Golden Delicious apple samples (Mildner-Szkudlarz et al, 2003), while the Pyrus Malus apple was separated by the large distances as an individual group which is clearly illustrated in Figure 5.…”
