“…There was a significant difference for fruit weight, epicarp and endocarp contents (wet basis -WB), pulp moisture, pulp oil content (dry and wet basis) and pulp oil yield and total oil yield/fruit (WB) (p<0.05). The fruit weight varied from 29 to 38 g (fresh weight), which is consistent with the average result (39 g) reported by Vianna et al (2017) and in the range of 24 to 58 g observed for 35 genotypes by Conceição et al (2015b). The fruits showed epicarp and endocarp contents varying from 15 to 24% and 28 to 35% (WB), respectively, and both comprised around half of the fruit weight.…”

“…The potencial of macauba as an oil source has been evaluated focusing on biodiesel production (BERGMANN et al, 2013;COLOMBO et al, 2018;CONCEIÇÃO et al, ,a, b, 2015bFERRARI and AZEVEDO FILHO, 2012;LOPES and STEIDLE NETO, 2011). Therefore the oil content and the fatty acid profile of both the mesocarp and kernel oils and fruit characteristics have been more studied than its nutritional value (CONCEIÇÃO et al, ,a,b, 2015bHIANE et al, 2005;VIANNA et al, 2017). Information related to nutritional composition is scarce, and a large variation has been observed for the protein content of the mesocarp ranging from 1.5 to 6.7% (RAMOS et al, 2008;COIMBRA and JORGE, 2011), while total dietary fiber has been presented for some macauba genotypes without evaluating the sugar content.…”

Macauba (Acrocomia aculeata) has mainly been evaluated as an oil source focused on biodiesel production. Furthermore, the fruit mesocarp and kernel are edible, and candies, jelly, sweet alcoholic liquor and ice cream are also produced from the mesocarp. Despite its consumption, there is still a lack of information on the nutritional composition of macauba. Selected macauba genotypes producing fruits with a sweet mesocarp were evaluated regarding the fruit characteristics, proximate composition, oil content and fatty acid profile. The mesocarp total sugar (fructose and glucose) content ranged from 4.5 to 9.6 g/100 g, total dietary fiber varied from 6.8 to 9.3 g/100 g, while protein content was up to 2.2 g/100 g (wet basis). There was a significant difference among genotypes for fruit characteristics, pulp oil content (7-29 g/100 g wet basis), and fatty acids from the mesocarp such as C18:1 (36-63%), C18:2 (7-35%) and C18:3 (0.8-7%)(p<0.05), and one of the evaluated genotypes may contribute to daily intake of linoleic and linolenic acids. The carotenes in the mesocarp oil ranged from 30-240 mg/kg. Lauric acid was the main fatty acid in the kernel oil. The differences observed depended on the genetic diversity and point out the nutritional value and different applications for macauba mesocarps.

“…The taxonomic distinction of the species has been demonstrated based on morphological data and geographic distribution [4], leaf anatomy [1], and fruit biometry [68]. However, A. totai is commonly regarded as A. aculeata due to the pronounced morphological similarity of both species, and because both have fruits with similar biometric and color characteristics [68]. Our results were congruent with the current taxonomic classification of the species.…”

Acrocomia (Arecaceae) is a genus widely distributed in tropical and subtropical America that has been achieving economic interest due to the great potential of oil production of some of its species. In particular A. aculeata, due to its vocation to supply oil with the same productive capacity as the oil palm even in areas with water deficit. Although eight species are recognized in the genus, the taxonomic classification based on morphology and geographic distribution is still controversial. Knowledge about the genetic diversity and population structure of the species is limited, which has limited the understanding of the genetic relationships and the orientation of management, conservation, and genetic improvement activities of species of the genus. In the present study, we analyzed the genomic diversity and population structure of seven species of Acrocomia including 117 samples of A. aculeata covering a wide geographical area of occurrence, using single nucleotide Polymorphism (SNP) markers originated from Genotyping By Sequencing (GBS). The genetic structure of the Acrocomia species were partially congruent with the current taxonomic classification based on morphological characters, recovering the separation of the species A. aculeata, A. totai, A. crispa and A. intumescens as distinct taxonomic groups. However, the species A. media was attributed to the cluster of A. aculeata while A. hassleri and A. glauscescens were grouped together with A. totai. The species that showed the highest and lowest genetic diversity were A. totai and A. media, respectively. When analyzed separately, the species A. aculeata showed a strong genetic structure, forming two genetic groups, the first represented mainly by genotypes from Brazil and the second by accessions from Central and North American countries. Greater genetic diversity was found in Brazil when compared to the other countries. Our results on the genetic diversity of the genus are unprecedented, as is also establishes new insights on the genomic relationships between Acrocomia species. It is also the first study to provide a more global view of the genomic diversity of A. aculeata. We also highlight the applicability of genomic data as a reference for future studies on genetic diversity, taxonomy, evolution and phylogeny of the Acrocomia genus, as well as to support strategies for the conservation, exploration and breeding of Acrocomia species and in particular A. aculeata.

Given the good prospects for its genetic improvement and domestication, current production is expected to rise above 6500 kg oil•ha -1 •yr -1 , provided that in recent studies the figures for extracted oil have already exceeded this amount for scenarios of 400 plants•ha -1 , surpassing even African oil palm in terms of liters of biodiesel•ha -1 (Colombo et al, 2017;Luis and Scherwinski-Pereira, 2017;Vianna et al, 2017).…”

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.
