The macauba almonds (Acrocomia aculeata) have aroused great economic and nutritional interest as they are a promising source of chemical compounds and oils with high oxidative stability. This study proposed to carry out the characterization of the physicochemical composition and to evaluate the quality parameters of the macauba almond, as well as to verify the amounts of fatty acids, peroxides and selenium present in the macauba's oil. This is a field and laboratory research of qualitative nature. Among the main results, high levels of ash (1.37 g/100g-1), proteins (12.12 g/100g-1) and fibers (11.31g/100g-1) were found in the almond, placing it in front of other oilseeds due to superiority of these nutrients. In the oil, a low presence of free fatty acids (2.30% w/w) and peroxides (0.56 meq Kg oil-1) was detected, indicating that this food has high oxidative stability. As for the selenium content, no significant presence of this mineral was identified in both foods. As a result, it is concluded that the almond and the oil of the macauba almond can be inserted in the market as a viable strategy aimed at people who wish to positively modify their diet, as they present satisfactory physicochemical characteristics and quality parameters.

‘Arauco’ forms part of the over two thousand olives (Olea europaea L.) varieties identified worldwide with the peculiarity of being the only recognized variety from Argentina. In this work, the fruit and oil characteristics from the ‘Arauco’ variety cultivated in the three main olive growing zones of Mendoza province (Argentina) were evaluated over two harvests (2016 and 2017). The characteristics assessed were oil and water concentrations, pulp/pit ratio, industrial yield, oxidative stability, fatty acid profile, total phenols and total flavonoids, among others. The results showed relatively high oleic acid and phenolic contents, together with low acidity and extinction coefficients (K232 and K270), as well as a well-balanced fatty acid profile. In addition, three interesting relationships among oxidative stability and ratios of monounsaturated fatty acids/polyunsaturated fatty acids (R2=0.96), oleic/linoleic (R2=0.96) and stearic acid (R2=0.93) were observed. These results showed that the ‘Arauco’ variety cultivated in Mendoza provides excellent oil quality.

Abstract This study aimed to evaluate the effects of different supplemental fat sources [soybean oil (SBO) as a source of n-6 fatty acid and fish oil (FO) as a source of n-3 fatty acids] in the starter feed of milk-fed dairy calves during the hot season. Forty Holstein calves (3 d of age; 39.67 kg of body weight; ten calves per group) were randomly assigned to the experimental treatments as follows: (1) starter feed supplemented with no fat source (CON), (2) starter feed supplemented with 3% SBO (DM basis), (3) starter feed supplemented with 3% FO (DM basis), and (4) starter feed supplemented with an equal mixture of SBO and FO (1.5% each, DM basis). The milk feeding schedule was constant for treatments and all calves were weaned on d 65 of age. Results show that calves had greater starter intake, average daily gain, and body length when fed SBO compared to other treatments. However, feed efficiency was increased and inflammatory indicators (tumor necrosis factor-alpha, serum amyloid A and haptoglobin) concentrations were reduced in the calves fed FO compared to the other treatments. In summary, it was revealed that SBO rich in n-6 FA improved starter intake and growth performance, while FO rich in n-3 FA could improve the immune function of calves. Due to the current experimental condition, an equal mixture of SBO and FO (1.5% each, DM basis) can be recommended to have an optimum growth performance and immune function while the calves are reared under the heat conditions.

Chemotaxonomic Study

A chemotaxonomic study was carried out on representative strains of 13 Aeromonas genomic species. Quinone, polyamine, and fatty acid patterns were found to be very useful for an improved characterization of the genus and an improved differentiation from members of the families Enterobacteriaceae and Vibrionaceae. The Q-8-benzoquinone was the predominant ubiquinone, and putrescine and diaminopropane were the major poly amines of the genus. The fatty acid patterns of 181 strains, all characterized by DNA–DNA hybridization, showed a great homogeneity within the genus, with major amounts of hexadecanoic acid (16:0), hexadecenoic acid (16:1), and octadecenoic acid (18:1), and minor amounts of the hydroxylated fatty acids (3-OH 13:0, 2-OH 14:0, 3-OH 14:0) in addition to some iso and anteiso branched fatty acids (i-13:0, i-17:1, i-17:0, and a-17:0). Although some differences in fatty acid profiles between the genomic species could be observed, a clearcut differentiation of all species was not possible.Key words: Aeromonas, polyamines, quinones, fatty acids, differentiation.
