The flavor and biochemical quality of peanuts obtained from Argentina,
China, and USA for the crop years 1986, 1987, and 1988 were evaluated
for composition, descriptive sensory properties and gas chromatograph
ic volatiles. Roasted peanutty flavor was more intense in USA-grown pe
anuts, and fruity/fermented, an undesirable flavor, was less intense i
n USA-grown peanuts than peanuts from the other two origins. Flavor at
tributes in Argentina-grown peanuts varied more among crop years than
the others. Similar patterns occurred for the corresponding volatile c
ompounds. Sugar content was greater, while lipid and Kjeldahl nitrogen
contents were less in the Argentina-grown peanuts than peanuts from t
he other two origins.
