Acetone Extracted Cottonseed Meals Without Catty Odors

摘要

ABSTRACTDclintered cottonseed was hulled and flaked. Moisture‐adjusted cooked and uncooked samples were either dried or left undried, and all sampleswerethen Soxhlet‐extracted with acetone for five hours and desolventized. Sensory testing of gruels prepared from the meals indicated that if free moisture was not present during acetone extraction, catty odors were not found in extracted meals. Gas chromatographic analyses of acetone extracted meals showed concentrations of 0.3 ppm mesityl oxide and 0.7 ppm diacetone alcohol, believed to be catty odor precursors, in a catty‐odorless meal, whereas concentrations of 1.6 ppm and 0.8 ppm, respectively, were found in a product with a catty
