  Objective: The aim of this work was to determine the fatty acids content in corn seeds oil (Zea mays) sample cultivated in Ecuador.Methods: Corn oil was obtained from corn oil seeds using the cold pressing method. Methyl esters fatty acids analysis were carried out using the gas chromatography (GC) method with a mass selective detector and using the database library NIST 14.L to identify the compounds present in the corn seed oil.Results: Methyl esters fatty acids were identified from corn (Z. mays) seeds using the GC mass spectrometer (GC-MS) analytical method. Fatty acids were analyzed as methyl esters on a capillary column DB-WAX 122-7062 with a good separation of palmitic acid, stearic acid, oleic acid, elaidic acid, linoleic acid, arachidic acid, and linolenic acid. The structure of methyl esters fatty acids was determined using the GS-MS method. Corn oil has a high content of linoleic acid (omega 6) with a value of 52.68% of the total content of fatty acids in corn oil and 29.70% of oleic acid (omega 9) of the total content of fatty acids in corn oil. The sample presented a value of 12.57% of palmitic acid.Conclusions: Corn oil shows a good content of fatty acids omega 6 and 9. The higher value was of omega 6 with 52.68% content. Corn oil has a good proportion of polyunsaturated of lipids (53.80%) and 14.86% of saturated lipids.

Single Meal

Eight adult female dogs (8 to 10 kg) with thoracic duct fistula were fed 5 to 10% solutions of mixed plant sterols in oleic acid, corn oil, or butter. The lymph, which flowed at a rate of 20 to 50 ml per hour, was drained for 18 to 26 hours. Each 2-hour collection was analyzed separately for cholesterol and plant sterols. Under comparable conditions and following a single meal containing plant sterol, about 35 mg of this sterol was transferred to lymph in 24 hours when corn oil was fed and 130 mg in the case of butterfat. At the time of maximum sterol absorption (8 to 12 hours after feeding) as much as 15% of the total lymph sterol was contributed by the plant sterols. Significant absorption of both β- and γ-sitosterol was observed, the γ-isomer being assimilated some 4 to 5 times as readily as the β-isomer. About 50% of the total lymph cholesterol was esterified. Essentially all of the absorbed plant sterol was free.

Low Fat Diet

Rats fed corn oil or a mixture of lard and olive oil produced as many offspring as those receiving no fat supplement with a low-fat commercial meal, but the weanling weight was lower. Although rats fed rapeseed oil continued to reproduce they had fewer and smaller offspring than rats fed other diets.The composition of fatty acids in the milk varied with the dietary fat of the mother. Animals receiving the low-fat diet secreted predominantly saturated fatty acids. A high proportion of linoleic acid appeared in the milk when corn oil was fed, and of oleic acid when the mixture of lard and olive oil was fed. Eicosenoic and erucic acids were present in the milk of rats receiving rapeseed oil, but were less prevalent than in the original oil.

Oleic acid (OA) and formic acid (FA) react to formoxystearic acid (FSA), in the presence of acidic catalysts.This reaction is of interest as OA can be obtained from renewable resources and FSA is a potential precursor for biopolymers.We have recently studied the liquid−liquid equilibrium (LLE) in the uncatalyzed nonreacting system OA + FA + FSA. Thiswork is extended here to the reactive system, in which a reactive liquid−liquid equilibrium (RLLE) exists. The reactionequilibrium is studied by quantitative NMR spectroscopy at temperatures between 333 and 353 K in homogeneous OA-richmixtures. This information is combined with that on the LLE to determine the RLLE. The physicochemical equilibria aremodeled in a thermodynamically consistent way using the associating lattice cluster theory (ALCT). Furthermore, data on thechemical equilibrium of the formation of the OA-isomer elaidic acid (EA) is supplied. Also the decomposition of FA and theformation of estolides (EL), which are oligomers of OA and EA, was observed and quantified.
