Abstract: There is a need for knowledge on new sources of vegetable oils. Acrocomia aculeata is regarded as a promising alternative source to meet food and industrial demands. With a similar productive potential to Elaeis guineensis, this crop is among the highest oil‐yielding plants in the world. The present study characterizes the A. aculeata oil comprehensively to aid the setting up of standards encompassing the quality, composition, and identity.
Samples are obtained under five different pressing conditions and screened regarding quality parameters. The coldly pressed sample, which shows the highest tocols content (85.5 mg kg−1), the higher oil stability index (6.4 h), and an acid value of 1.6 mg KOH g−1 is characterized in terms of chemical, physical, and identity characteristics, i.e., peroxide value, insoluble impurities, mineral contents, fatty acids essential composition, iodine value, saponification value, kinematic viscosity, relative density, unsaponifiable matter, and total carotenoids. Results are compared with the literature sources to assess A. aculeata as an alternative feedstock.
The study contributes to evidence that products derived from A. aculeata may have good consumer acceptance, nutraceutical value, and natural appeal. It is suggested that the compliance to legal standards must be pursued to guarantee the sustainability of the productive crop chain.
