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. Practical Applications: This paper contributes an assessment of the quality parameters of Acrocomia aculeata oils as Functional Food and alternative industrial feedstock. A comprehensive characterization of the oil studied will help food scientists, industry and food processing research to set up standards concerning composition, identity and health‐related topics regarding one of the highest oil‐yielding plants in the world. A comprehensive characterization of edible vegetable oils mechanically extracted from the mesocarp of fresh Acrocomia aculeata fruit is carried out to consider the assessment of different temperature conditions and subsequent pressings. Quality, composition, and identity characteristics of the crude oil are obtained to set up standards also on health‐related topics.

“…This palm has similar characteristics to those of other forestry or agricultural residues widely used in the production of biofuels, and is already acclimated to subtropical climates because it is native to Brazil (Cardoso et al, 2017;César et al, 2015). Such adaptation of macauba to a highrange of hydrothermal stressors facilitates the extension of its cultivation and exploitation to marginal lands with grassland coverings and its implantation in slopes.…”

“…Macauba palm can open up a wide range of possibilities upon combination with livestock activity, with associated savings in fertilizers and the elimination of herbicides throughout the life cycle of the crop (Araújo et al, 2017;Delucchi, 2010). By-products generated after the extraction of the oil are susceptible of use as animal feed (Ali et al, 2017a;Ali et al, 2017b;Costa Júnior et al, 2015;Henrique Bernardes Pereira et al, 2013), and the endocarp of the fruits can be employed for vegetal carbon production (Bhering, 2009; Ministério do Desenvolvimento Agrário, 2014), as a biosorbent for heavy metals removal in wastewater (Altino et al, 2017;Vieira et al, 2012), or for biokerosene production (Cardoso et al, 2017;Zelt, 2018). Finally, other alternative uses would be related to the potential applications of the bioactive compounds present in its oil and in some other plant by-products (Dario et al, 2018;Lescano et al, 2014;Oliveira et al, 2016;Shahidi and de Camargo, 2016;Souza et al, 2017a).…”

The 450 Scenario, which limits the increase in global average temperature to 2 ºC, makes it necessary to take steps towards a low-carbon economy. Since the energy sector is a major contribution to anthropogenic greenhouse gas (GHG) emissions, the production of biofuels can play a key role in strategies aimed at climate change mitigation. In this regard, the oil derived from macauba palm (Acrocomia aculeata), mainly constituted of saturated organic chains, has been claimed to hold promise for the production of liquid fuels. The high potential yield, diversity of co-products and various positive features of this emerging energy crop make it an interesting option both from a social and an environmental point of view. Nonetheless, a full environmental evaluation is still missing. In the study presented herein, the impacts produced in its plantation, cultivation and harvesting phases and the associated cumulative energy demand P r e p r i n t 2 have been determined using a life cycle analysis methodology, in addition to shedding some light on its GHG intensity relative to the other energy crops it can displace. Excluding land use changes and biogenic CO 2 fixed by the crop, it was concluded that to produce one ton of macauba fruit in Brazil, the system would absorb 1810.21 MJ, with GHG emissions of 158.69 kg CO 2 eq in the 20-year timeframe, and of 140.04 kg CO 2 eq in the 100-year timeframe (comparable to those of African oil palm). Damage to human health, ecosystem quality, and resources would add up to 16 Pt•t-1 according to Eco-indicator 99 methodology. In order to account for the uncertainty derived from improvement and domestication programs, which should affect current production levels, a sensitivity analysis for different productivities was performed. In all analyses, fertilization was found to be responsible for ca. 90% of the impacts, and hence special attention should be paid to the development of alternative fertilizer management schemes.

The oilseed palm genus Acrocomia is suitable for sustainable oil production in South America. The high phenotypic diversity of wild populations poses a challenge for the delimitation of the genus. Comparing the inflorescence architecture, a first‐order panicle, and staminate and pistillate flower traits could be a valuable tool in resolving the taxonomic disarray. Thus, this study aims to characterize the differences in the inflorescence architecture and floral structures of three common and economically significant Acrocomia species: A. aculeata, A. totai, and A. intumescens. Biometric traits of the inflorescence architecture and floral structures of various Acrocomia accessions in an ex situ germplasm collection in Brazil were assessed. The unweighted pair group method with arithmetic mean (UPGMA) cluster analysis based on the Gower distance was used to measure dissimilarities between the individual plants of the accessions. To our best knowledge, this study provides the first evidence of the presence of second‐order rachillae in the genus Acrocomia. Evaluated traits showed a high level of variation within and between accessions, emphasizing the phenotypic diversity of the genus. The accessions of A. totai were distinguishable from those of the other two species by their inflorescence architecture and flower traits. The dissimilarities between A. aculeata and A. intumescens were not sufficient to differentiate both. In conclusion, the quantitative assessment of inflorescence and floral traits is a valuable tool for taxonomic resolution of the genus.
