 +Of the 10 odorants detected in raw peas by GC-O, the highest OAV were calculated for 3-methylbutanoic acid (382; sweaty, rancid), hexanal (280), and (E)-2-octenal (8). Aroma recombination and omission experiments showed that a noticeable difference in aroma was perceived when hexanal and benzaldehyde were omitted from the model. "In addition, the omission of (E)-2-octenal, 3-methylbutanoic acid, (Z)-2-penten-1-ol, and benzyl alcohol resulted in significant changes in aroma." \\

 +The most potent flavor compound of raw pea milk was 2-methoxy-3-isopropyl-(5 or 6)-methylpyrazine, followed by hexanal, (E,E)-2,4-nonadienal, (E,E)-2,4-decadienal, 1-octen-3-ol, and 2-pentylfuran. \\

 +"...pea aroma is a product of complex interactions of a large number of volatiles. The volatiles are either already present natively in the pea or are formed during harvesting/processing, indicating that often aroma profile changes are essentially caused by fat oxidation products." \\
