“…The average fatty acid contents (Table 1) in 13 genotypes investigated in this study were similar to the values most common for fatty acid contents in commodity soybean (Fehr, 2007) and the values determined in many studies with different sets of soybean germplasm (Chen, 1995;Rani et al, 2007; Fan et al, 2015; Priolli et al, 2019; Abdelghany et al, 2020). The tested material exhibited significant phenotypic variability for the mentioned traits.…”

“…The calculated ratios provide even more information on the value of the soybean oil (Tables 1 and 2). If we consider that the optimal MUFA/PUFA ratio is > 0.5 for soybean (Rani et al, 2007), the average value of 0.43 would indicate a poor oxidative stability. The average OA/LA value of 0.48 further corroborates the claim that the soybean oil, although rich in the essential omega-6 fatty acid, has a low oxidative stability.…”

“…A poor oxidative stability prevents the use of oil at high cooking temperatures, reduces the shelf-life, and causes off-flavors (Lee et al, 2007). An oxidative stability of the soybean oil, determined by a MUFA and PUFA ratio (MUFA/PUFA) (Rani et al, 2007), can be improved by a trans-isomer producing catalytic hydrogenation or by breeding for a higher OA content (Wilson, 2004;Lee et al, 2007;Rani et al, 2007). The diets rich in trans-fatty acids increase the risk of cardiovascular diseases (Brouwer et al, 2010), so increasing the OA is considered a better option.…”

The purpose of this study (2010‒12) was to investigate the fatty acid profiles (palmitic – PA, stearic – SA, oleic – OA, linoleic – LA, linolenic – LNA, saturated fatty acids – SFA, monounsaturated fatty acids – MUFA, polyunsaturated fatty acids – PUFA), oxidative stability (MUFA/PUFA, OA/LA), and nutritive quality (LA/LNA) of oil produced by 13 early soybean genotypes created at the Agricultural Institute Osijek, Croatia. The analysis of variance determined significant effect of genotype (G), year (Y), and GxY interaction on all examined traits. The correlation analysis indicated the most important positive correlation existed between the SA and OA, SA and LNA, and LA and LNA, and the most important negative relationship between OA and LA, and OA and LNA. The principal component analysis yielded four significant principal components (PCs) with the eigenvalues > 1, which together accounted for 57.84% of the total variability in the data set. The Eigen analysis of the correlation matrix loadings indicated MUFA/PUFA, MUFA, OA/LA, and OA mostly contribute to the PC1 axis and are in a positive correlation with it, while PUFA, LA, and LNA mostly contribute to a negative direction. These results will facilitate the planning of future breeding programs, aimed at adjusting the fatty acid profiles according to the needs of the processing industry and end consumers.

“…However, the soybean meal (after oil extraction) used in animal feeding is almost fatty acid free. Linolenic acid is a precursor of longer-chain PUFAs, i.e., eicosapentaenoic acid (EPA: C20:5ω −3) and docosahexaenoic acid (DHA: C22:6ω −3), which are not biologically synthesized by humans [49]. Hence, a linolenic acid supply is needed in the diet of humans.…”

The present study evaluates the green biomass of Jerusalem artichoke (JA) as an alternative green protein. A leaf protein concentrate (LPC) was prepared from leafy shoots using biotechnological methods. Seven clones were compared to assess the importance of the genetic basis of JA, and alfalfa served as the control. The LPC content of JA was an average 39 g kg −1 of fresh biomass, while that of alfalfa was 32 g kg −1. The JA can produce up to 936 kg of protein ha −1 year −1 without fertilization under rainfed conditions. The crude protein content of the LPC varied from 24.2 to 31.4 m/m%, depending on clones and harvesting time, which was comparable to that of alfalfa LPC (~32.3%). The amino acid profile of the LPC of JA, particularly of the essential amino acids, was similar to alfalfa and soybean. In addition, our results confirmed that the polyunsaturated fatty acid (PUFA) content varied between 64 and 68% in the LPC fraction, regardless of the clone that was used, with linoleic acid and linolenic acid being the predominant PUFAs. In addition, unlike alfalfa, the content of arachidonic acid was 0.5% in the JA LPC. The tuber yield was significantly reduced because of the repeated harvesting of the shoot parts; however, the tubers obtained were sufficient to regenerate the plantation in the subsequent year, thus ensuring the renewable ability and sustainability of the green biomass of JA.

Aims: To extract and characterize oils from Glycine max L. (soya bean seed), Elaeis guineensis (palm kernel seed) and Cocos nucifera (coconut) using ethanol and n-Hexane. Place and Duration of Study: Department of Industrial Chemistry, Renaissance University, Ugbawka, between December 2017 and July 2018. Methodology: Using Soxhlet extraction method, the milled seed samples (soya bean, coconut and palm kernel) were bagged and extracted with accurately measured quantity of each solvent (n-Hexane and Ethanol). Physicochemical analysis which includes: Acid values, iodine value, free fatty acid (% oleic) and saponification value was carried out on the extracted oil. Results: The percentage oil yield from ethanol extracts were 8.58% (8.58 g), 26.01% (26.01 g) and 31.21% (31.21 g) for soya bean, coconut and palm kernel respectively while that of n-Hexane extracts were 14.69% (14.69 g), 31.85% (31.85 g) and 45.28% (45.28 g), due to the fact that 100 g of the milled sample was used. Free fatty acid values were the same in n-Hexane and ethanol extracts of soya bean oil. These values were slightly higher in the coconut and palm kernel oil extracts using ethanol. Acid values were observed to be slightly higher in the ethanol extracted oils. The Saponification values were generally higher in ethanol extracted oils than in hexane extracted oils. There was maximum oil recovered with hexane than ethanol when the extraction process was carried out for 120 minutes. Conclusion: In spite of the fact that n-Hexane gave a better extraction yield, ethanol appeared to be a better alternative for the extraction process because it is green, less toxic and safer to handle.
