The author studied the oil-expression of colza-seed by using super-sonics and as a result of this experiment, following facts were obtained.
(1) The cell-wall of colza-seed changed partially and its rigidity reduced from 1.18kg to 1.06kg (about 10%).
(2) The volume which decreased by compression increased with the raise of pressure, decreased with the number of compression.
(3) The rate of oil-expression in the case of super-sonics division was 35.6% in raw seed, 47.5% in flattened seed and 82.0% in high pressure (about 100kg/cm2). These values were respectively 4.7%, 15.9% and 21.0% higher than those of common division
Especially in high pressure compression the rate exceeded in other present expression methods.
