“…As the erucic acid (C 22:1) content of the faecal fat is higher than that of the dietary fat, it can be concluded that the erucic acid fraction of RSO is especially poorly digested. This was also shown by Rocquelin and Leclerc [21],…”

“…This difference can largely be ascribed to the decrease in food intake induced by RSO [15,28], However, in paired feeding experiments in which control animals were allowed to eat as much as animals offered an R SO-containing diet, the con trols still grew more than the RSO-fed animals [22,32], This was explained [32] by the well-documented poorer digestibility of the rapeseed oil [21,29]; however it has never been investigated to see if the poorer digestion of RSO was compensated for by a better digestion of other dietary components.…”

Rats were fed diets containing 60 cal% rapeseed oil (RSO) or sunflowerseed oil (SSO) for periods up to 64 weeks. When the animals were allowed to eat ad libitum, the food consumption in the RSO group was significantly lower than in the SSO group. It was shown that the RSO diet is less readily digested than the SSO diet. This is due solely to the lower digestion coefficient of the RSO and of its erucic acid fraction in particular, which can be explained by its chain length. The digestion coefficient of the non-fat calories is equal in both groups. The digestion capacity is not a limiting factor in RSO digestion. The absorbed erucic acid is almost totally metabolized. Rats fed a RSO-containing diet utilize the digested calories less efficiently than animals offered an SSO diet. Moreover, their oxygen consumption and water-vapour release are higher. It is assumed that the lower efficiency of the RSO diet is caused by a slightly uncoupled oxidative phosphorylation and a greater heat increment.

Summary. The triacylglycerol structure of perirenal adipose tissue from rats fed peanut oil.Weanling male rats were fed a balanced diet containing 15 p. 100 peanut oil by weight. The digestibility and fecal excretion of oil fatty acids were studied for 8 days at the beginning of the diet, which was then continued up to 4 months. At the end of the experiment, perirenal adipose tissues were removed and their triacylglycerols isolated and studied. They were fractionated into 8 fractions according to unsaturation and then analyzed by gas-liquid chromatography (GLC) for fatty acids and triacylglycerols. Each fraction was submitted to pancreatic lipolysis ; the mono-and diacylglycerols formed were isolated and their fatty acids analyzed by GLC. The diacylglycerols were further fractionated according to unsaturation and their fatty acid composition analyzed. The triacylglycerol structure of the adipose tissue was determined using mathematical methods previously described.

Summary. Digestibility and fecal excretion patterns of erucic and brassidic acids esterified in triglycerides of different structure. A comparative study in the rat.The digestibility and fecal excretion patterns of erucic (cis n-9 docosenoic) and brassidic (trans n-9 docosenoic) acids, esterified in triglycerides of different structure, were compared in the rat. Synthetic triglycerides were prepared either by mixing or interesterifying trierucin or tribrassidin with an equal amount of corn oil. Rapeseed and peanut oils were used as references. The apparent digestibility of trierucin mixed or interesterified with corn oil was similar to that of peanut oil but higher than that of rapeseed oil. The high amount of 2-monoerucin resulting from diets containing trierucin explained the improved digestibility of erucic acid as compared to that of rapeseed oil which had a very small erucic acid content on the 2-position. It also seemed that 2-monoerucin enhanced the digestibility of saturated fatty acids. Tribrassidin mixed with corn oil had a poor digestibility because pancreatic lipase hydrolysis was delayed in the intestinal lumen. The high melting point of the homogeneous triglyceride was responsible for that phenomenon. The interesterification of tribrassidin with corn oil, which drastically lowered the melting point of the mixture from 52 to 37 o C, improved both the hydrolysis of the triglycerides and the digestibility of the C 22 : 1 trans fatty acid as well as that of the other fatty acids in the diets. Nevertheless, the unabsorbed brassidic acid in every case was principally excreted in the form of a compound insoluble in organic neutral solvent. In that respect, brassidic acid behaved like shorter chain saturated fatty acids such as palmitic and stearic acids.Introduction.
