The objective of this work was to study the economical viability of supercritical fluid extraction (SFE) of oil and carotenoids from three Amazonian palm trees: buriti, pupunha and pressed palm fiber (PPF). Literature experimental SFE data were used to estimate the cost of manufacturing (COM) of oils and carotenoids present on the crops, considering five main costs: fixed cost of investment, operational labor, utilities, waste treatment and raw material. SFE at 40 ºC / 300 bar, 50 ºC / 250 bar and 45 ºC / 300 bar presented the lowest COM for buriti, pupunha and PPF oils, respectively. The time of extraction determines carotenoids concentration on the oils. Under the conditions studied, the prices of SFE oils were higher than the selling prices of pressed oils, not because of the investment cost, but because of the raw material cost. Nevertheless, it is known that SFE oils are generally richer in carotenoids, which should determine for them higher selling prices and special uses.
