TL;DR: In this article, an analytical method has been developed using Fourier transform infrared spectroscopy (FTIR) to determine biodiesel content in the reaction mixture to monitor the transesterification reaction.
Abstract: An analytical method has been developed using Fourier transform infrared spectroscopy (FTIR) to determine biodiesel content in the reaction mixture to monitor the transesterification reaction. It is also shown that it can be used to determine biodiesel content in biodiesel−petrodiesel blends. The method with small modifications can also be used to determine the oil content in the adulteration of biodiesel−petrodiesel blends. Soybean oil is used as the model oil, and its methyl ester is used as biodiesel. The method uses a software viz. Enformatic FTIR Collection Manager (EFCM) to develop a calibration model and predict the concentration of biodiesel and oil. The software uses the nonlinear classical least square (CLS) method for calibration. It is shown that the method can be used to measure the amount of biodiesel accurately to the extent of 98.11% accuracy for biodiesel−oil mixtures and biodiesel content in the biodiesel−petrodiesel mixture (blend) with an accuracy of 99.99%. The method has also been us...

TL;DR: Both the level of 18∶3n−3 in the diet and its ratio to 18∵2n−6 were important in influencing long-chain n−3 fatty acid levels in platelet and plasma PL and that prostanoid production coincided with the diet-induced differences in PL fatty acid patterns.
Abstract: The effect of dietary alpha-linolenic acid (18:3n-3) and its ratio to linoleic acid (18:2n-6) on platelet and plasma phospholipid (PL) fatty acid patterns and prostanoid production were studied in normolipidemic men. The study consisted of two 42-d phases. Each was divided into a 6-d pre-experimental period, during which a mixed fat diet was fed, and two-18 d experimental periods, during which a mixture of sunflower and olive oil [low 18:3n-3 content, high 18:2/18:3 ratio (LO-HI diet)], soybean oil (intermediate 18:3n-3 content, intermediate 18:2/18:3 ratio), canola oil (intermediate 18:3n-3 content, low 18:2/18:3 ratio) and a mixture of sunflower, olive and flax oil [high 18:3n-3 content, low 18:2/18:3 ratio (HI-LO diet)] provided 77% of the fat (26% of the energy) in the diet. The 18:3n-3 content and the 18:2/18:3 ratio of the experimental diets were: 0.8%, 27.4; 6.5%, 6.9; 6.6%, 3.0; and 13.4%, 2.7, respectively. There were appreciable differences in the fatty acid composition of platelet and plasma PLs. Nevertheless, 18:1n-9, 18:2n-6 and 18:3n-3 levels in PL reflected the fatty acid composition of the diets, although very little 18:3n-3 was incorporated into PL. Both the level of 18:3n-3 in the diet and the 18:2/18:3 ratio were important in influencing the levels of longer chain n-3 fatty acid, especially 20:5n-3, in platelet and plasma PL. Production of 6-keto-PGF1 alpha was significantly (P < 0.05) higher following the HI-LO diet than the LO-HI diet although dietary fat source had no effect on bleeding time or thromboxane B2 production.(ABSTRACT TRUNCATED AT 250 WORDS)
