“…These values are similar to those obtained by other authors for the same species (Hiane et al, 2006;Chuba and Sanjinez-Argandoña, 2011). Machado et al (2014) revealed lower values (10. 49 g) for pulp from macauba fruit collected in the Paraná state.…”

Proximate composition, physical and chemical analysis of the pulp, kernel and oils of Acrocomia aculeata (Jacq.) Lodd. were investigated. The macauba pulp and the kernel represented 49 and 6.25% of the mass of the whole fruit, respectively. The main components present in the pulp and kernel are lipids (23.62 and 46.96%) and fibers (13.89 and 15.81%). Furthermore, the mineral analysis showed that the kernel had more micronutrients than pulp, principally Cu, Mn and Zn. The influence of extraction by pressing and Soxhlet extractor in different solvents regarding the quality and yield of the oils was evaluated. The highest yield in oil extraction was obtained by Soxhlet method, influenced by the type of solvent and part of macauba's fruit. For pulp, the better solvent is ethanol and ethanol 95%, and for kernel is ethanol, ethanol 95%, hexane and ethyl either. The analysis of the composition of fatty acids in the oil from the pulp and kernel showed that the monounsaturated fatty acids were predominant in the pulp oil, specially the oleic acid (C 18:1), and saturated fatty acids in the kernel oil, principally the lauric acid (C 12:0).

“…The fertilization treatments discussed in previous paragraph was deemed as optimal to maximize fruit production in the agrometeorological conditions of the area of study. The objective was to provide plants with the necessary macro-and microelements to complete their vegetative cycle, obtaining a favorable development and an excellent productivity, without introducing factors that could alter the potential of biomass per unit of area (Machado et al, 2015).…”

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 consumption of macaúba fruit is possible because it has nutritional potential, and may be an important source of nitrogen, phosphorus, potassium, calcium, manganese, iron, copper, zinc, and bromine (Machado et al, ; Oliveira et al, ). Macaúba also exhibit immunoadjuvant, anti‐inflammatory, and antioxidant potential.…”

This study investigated the effects of variations in oil contents and fatty-acid composition, density, viscosity, acid values, saponification values, specific oxidative stability, and antioxidant concentration of Acrocomia totai kernel oil during fruit maturation. Fatty acids were quantified using 1 H nuclear magnetic resonance (NMR) spectroscopy, gas chromatograph-flame-ionization detector (GC-FID), and Fourier transform Raman (FT-Raman) spectroscopy analyses. The results showed that all physicochemical characteristics and oil composition changed during the ripening stage. The CG-FID analysis showed a reduction in the unsaturated fatty-acid content (from 78.8% to 22.1%), with a proportional increase in the saturated fatty-acid contents (from 21.6% to 77.9%). The difference in the fatty-acid composition was confirmed by analysis of the 1 H NMR and FT-Raman spectra. The degree of unsaturation was calculated to determine the oxidative stability of oil. These results suggest that the fruit's maturation contributes to the specific oxidative stability. The antioxidant concentration revealed higher contents of carotenoids in the ripe fruit (0.16 mg of carotenoid per 100 g KERNEL ) when compared to the unripe fruit (0.05 mg of carotenoid per 100 g KERNEL ). In the total phenolics analysis, there was no change in concentration over ripening time. These results show that kernel oil has physicochemical properties comparable with high-quality commercial vegetable oils, suggesting that it is a promising alternative to conventional vegetable oils.
