“…Ilha et al (2014) showed that the biodiesel obtained from Acrocomia aculeata has acceptable properties for use in diesel engines; however, due to the predominant composition of unsaturated fatty acids, it requires the use of an antioxidant additive. Macauba oil is obtained from the pulp and almond, wherein the pulp comprises ~45% of the fruit (Ramos et al, 2008) and has between 18.7 to 29 wt% of oil (Coimbra and Jorge, 2012;Ciconini et al, 2013). The literature reports the high FFA content in macauba pulp oil (Doná et al, 2013;Aguieiras et al, 2014;Iha et al, 2014;Navarro-Díaz et al, 2014;César et al, 2015), between 10.5 to 65.4 wt%, due to the presence of fatty acids in the fruit tissues of Acrocomia aculeate (César et al, 2015) and because the oil is obtained by pressing and filtration without refining steps.…”

-This study evaluated the potential of macauba pulp oil (MPO) as a feedstock for continuous ester production using ethanol under pressurized conditions. Experiments were performed in order to obtain data for the effect of process variables on ethyl ester (FAEE) and free fatty acid (FFA) conversion in a catalyst-free process. From the results, it appears that the MPO to ethanol mass ratio and the pressure were the variables with more favorable effect on the evaluated response variables. The addition of n-hexane caused an increase in the production of esters; however, this had a negative effect on FFA conversion. The addition of water was unfavorable for oil processing with high acidity. In this process, esterification and transesterification occur simultaneously, and the high FFA content in MPO provides high yields (85 wt% of esters; 93% FFA conversion) at low temperature, since the esterification reaction rate is higher than the transesterification. The decomposition of fatty acids was evaluated and levels <5% were observed under the evaluated experimental conditions.

“…There are studies of physico-chemical parameters of oils of some species of the family Arecaceae that demonstrate the possibility of the use in the production of biodiesel. Some exemples are Buriti (Mauritia flexuosa), Palma (Elaeis guineensis), Tucumã (Astrocaryum aculeatum), Macaúba (Acrocomia aculeata) and Jerivá (Syagrus romanzoffiana) (Barbosa et al, 2009;Cesar et al, 2015;Esteban et al, 2012;Coimbra & Jorge, 2012) Due to the few existing works on this species, studies on the oil potential of the fruits of this palm are necessary. Because it is important to look for new species that produce good quality oil for the production of biotechnological products such as biodiesel, since currently the production of this fuel occurs using as input mainly the soybean oil that is also used in food (No, 2011).…”

In Brazil there are several oleaginous plants, with the potential to supply oil as raw material for various types of industries (cosmetic, pharmaceutical, energy, among others), among them we have the Acrocomia emensis (Arecaceae) known as tucum rasteiro. The objective of this work was to realize: extraction of the oil of the almonds using two types of cold mechanical press (walrus type and manual hydraulic type of 15 tons), physical-chemical analyzes (acidity index, peroxides, refraction, moisture and volatile material, ash, viscosity and density at 25 ºC) and fatty acid profile of the oil extracted from almonds of A. emensis from three localities in the northern state of Minas Gerais, Brazil (Bonito de Minas, Brasília de Minas and Montes Claros). The values of the physical-chemical indexes varied among the samples from the different locations. Extraction using walrus type press provided higher yield. The fatty acids of the oils of the three origins were: caprylic, capric, lauric, myristic, palmitic, stearic, oleic and linoleic. The majority in the three samples were the lauric acid.

“…It may be found in different Brazilian ecosystems, including degraded areas (Motta et al 2002;Pires et al 2013). In addition, the fruits of this species have large oil content (Coimbra and Jorge 2012).…”

Ecophysiological leaf traits of native and exotic palm tree species under semi-arid conditions

AbstrAct:The main goal of this study was to evaluate the performance of two palm species under semi-arid conditions during the rainy and dry periods: the semi-arid native Syagrus coronata and a native to tropical America, Acrocomia aculeata. The leaf water potential, gas exchange, leaf soluble sugars, starch, free amino acids, total soluble protein content and morphological traits were measured.The highest leaf water potential and CO 2 assimilation values in both species were achieved during the rainy period. In response to the low soil moisture content during the dry period, gas exchange when compared with values from rainy period. As evergreen plants, both species maintained intact leaf photosynthetic pigment contents during the rainy and dry periods. Other important traits for drought tolerance are larger adaxial surface hypoderm and cuticle found in both species with higher stomatal density on the abaxial leaf surface.When comparing the species, S. coronata exhibited lower sensitivity to low water availability, showing higher CO 2 assimilation and water use efficiency.
