TL;DR: All diets containing Pollack residual oil were found to improve both survival and growth of prawn and the highest growth was obtained in the prawn group receiving 8% short necked clam lipid.
Abstract: The effects of dietary lipids on the growth and fatty acid composition of the prawn, Penaeus japonicus, were examined. The survival and growth of prawn kept on soybean oil diet were extremely low. However, all diets containing Pollack residual oil were found to improve both survival and growth. The highest growth was obtained in the prawn group receiving 8% short necked clam lipid. Dietary lipids affected the fatty acid composition of prawn lipids. The diets containing either pollack residual oil of short necked clam lipid elevated 20:5ω3 and 22:6ω3 levels as compared with soybean oil diet.

TL;DR: In this paper, the partial least squares (PLS) calibration method was used to develop a calibration model using Fourier transform infrared spectroscopy (FTIR) spectra data of biodiesel samples from different sources, such as cotton, castor, and palm, which were mixed with raw soybean oil to simulate an adulteration system.
Abstract: The partial least-squares (PLS) calibration method as a chemometric tool was used to develop a calibration model using Fourier transform infrared spectroscopy (FTIR) spectra data of biodiesel samples from different sources, such as cotton, castor, and palm, which were mixed with raw soybean oil to simulate an adulteration system. The PLS calibration method was applied with and without variable selection to quantify the amount of raw soybean oil present in these samples. Classic methods of variable selection, such as forward and stepwise, were applied to all origins together and each one separately. Variable selection improves not only the stability of the model to the colinearity in multivariate spectra but also the interpretability of the relationship between the model and the sample composition, which means that it becomes easier to determine and quantify the amount of raw soybean oil mixed in each biodiesel source.

TL;DR: In this paper, the authors studied the oxidative stability of soybean oil triacylglycerols with respect to composition and structure and determined the peroxide value and headspace analysis of volatiles of the oxidized triacylsglycerol (at less than 1% oxidation).
Abstract: The oxidative stability of soybean oil triacylglycerols was studied with respect to composition and structure. Crude soybean oils of various fatty acid and triacylglycerol composition, hexane-extracted from ground beans, were chromatographed to remove non-triacylglycerol components. Purified triacylglycerols were oxidized at 60°C, in air, in the dark. The oxidative stability or resistance of the substrate to reaction with oxygen was measured by determination of peroxide value and headspace analysis of volatiles of the oxidized triacylglycerols (at less than 1% oxidation). The correlation coefficients (r) for rates of peroxide formation (r=0.85) and total headspace volatiles (r=0.87) were related positively to oxidizability. Rate of peroxide formation showed a positive correlation with average number of double bonds (r=0.81), linoleic acid (r=0.63), linolenic acid (r=0.85). Rate of peroxide formation also showed a positive correlation with linoleic acid (r=0.72) at the 2-position of the glycerol moiety. A negative correlation was observed between rate of peroxide formation and oleic acid (r=−0.82). Resistance of soybean triacylglycerols to reaction with oxygen was decreased by linolenic (r=0.87) and increased by oleic acid (r=−0.76)-containing triacylglycerols. Volatile formation was increased by increased concentration of linolenic acid at exterior glycerol carbons 1,3 and by linoleic acid at the interior carbon 2. Headspace analysis of voltiles and high-performance liquid chromatography of hydroperoxides indicated that as oxidation proceeded there was a slight decrease in the linolenic acid-derived hydroperoxides and an increase in the linoleic acid-derived hydroperoxides. The oxidative stability of soybean oil triacylclycerols with respect to composition and structure is of interest to the development of soybean varieties with oils of improved odor and flavor stability.

TL;DR: Sunflower oil with the highest percentage of mono and polyunsaturated fatty acids especially the high linoleic-low oleic variety appeared to be superior and most suitable edible oil for mass consumption as mentioned in this paper.
Abstract: Fatty acid analysis of the five types of locally consumed edible oils (n = 22) was carried out using a Gas Chromatograph (G.C) equipped with a Flame Ionization Detector (FID) and stainless steel packed column. The results showed that sunflower oil contained the highest percentage of long chain mono and polyunsaturated fatty acids (91.49 ± 1.91 %) compared to soybean oil (81.14 ± 1.49 %), mustard oil (86.80 ± 3.07 %), palm oil (53.30 ± 0.36 %) and coconut oil (7.12 ± 0.51 %). Two varieties of mustard oil, low erucic (= 5 %, n=3) and high erucic acid ( >14 %, n=2) and two varieties of sunflower oil, high linoleic-low oleic (61-66 % & 22-27 %, n=2) and low linoleic- high oleic (29-38 % and 53-63 %, n =3) were found. Sunflower oil with the highest percentage of mono and polyunsaturated fatty acids especially the high linoleic- low oleic variety appeared to be superior and most suitable edible oil for mass consumption.
