the EE. Any pressure below 170 kg/cm2 is not
recommended.
Similar to the EE, higher extractability of b-carotene and lycopene
in the oil samples could be obtained by increasing pressure.
However, further increase in the pressure slightly reduced the
amount of carotenoids. As a result the pressure of 170 kg/cm2 is
considered as optimum for the carotenoid extraction.
