Extraction and Enzymatic Modification of Functional Lipids from Soybean Oil Deodorizer Distillate
Crude vegetable oils contain triacylglycerols as major component and various minor components such as diacylglycerols, monoacylglycerols, free fatty acids, phospholipids, tocopherols, sterols, squalene, color pigments, waxes, aldehydes, ketones, triterpene alcohols and metals that may affect the quality of the final product. The minor components are removed partially or entirely by either physi...
متن کاملRecovery of phytosterols from waste residue of soybean oil deodorizer distillate.
This study describes a catalytic decomposition and crystallization process to recover phytosterols from the waste residue of soybean oil deodorizer distillate (WRSODD). Various solvents were used for the crystallization of phytosterols. The effect of different solvents on the purity and yield of recovered phytosterols was investigated. The composition of WRSODD was analyzed by silica gel column...
متن کاملEnhancing Biodiesel Production from Soybean Oil Using Ultrasonics
Our objective was to determine the effect of ultrasonics on biodiesel production from soybean oil. In this study, ultrasonic energy was applied in two different modes: pulse and continuous sonication. Soybean oil was mixed with methanol and a catalytic amount of sodium hydroxide, and the mixture was sonicated at three levels of amplitude (60, 120, and 180 μmpp) in pulse mode (5 s on/25 s off). ...
متن کاملComparison study of biodiesel fuel production from sunflower oil using by ultrasound and heat
In this research, a comparison of biodiesel produced by ultrasound and heat methods was investigated. Methanol was used as the alcohol with molarity 3, 6 and 9 and KOH 0.5, 1 and 1.5 wt.% As a catalyst. In ultrasound technique, five vibrating pulse levels and three time levels were used. The results indicate that biodiesel produced by ultrasound in some properties includes a flash point of abou...
متن کاملBiodiesel production by esterification of palm fatty acid distillate
Production of fatty acid methyl ester (FAME) from palm fatty acid distillate (PFAD) having high free fatty acids (FFA) was investigated in this work. Batch esterifications of PFAD were carried out to study the influence of: including reaction temperatures of 70–100 1C, molar ratios of methanol to PFAD of 0.4:1–12:1, quantity of catalysts of 0–5.502% (wt of sulfuric acid/wt of PFAD) and reaction...
