Fenugreek seed oil

Abstract

Summary Comparison of the heretofore known analytical constants of the fatty oil with those herein reported show that the order of magnitude thereof is substantially the same. The list has been increased, however, to include values not previously recorded. A separation of the fatty acids of this oil has been made with the following approximate results: palmitic acid, 7.3 per cent; stearic acid, 2.4 per cent; arachidic acid, 0.9 per cent; behenic acid, 0.6 per cent; oleic acid, 21 per cent; linoleic acid, 37 per cent; and linolenic acid, 19 per cent.

Extraction of Fenugreek (Trigonella foenum-graceum L.) Seed Oil Using Subcritical Butane: Characterization and Process Optimization

“…The high saponification value (190.277 mg KOH/g of oil) of the oil indicated a high content of low molecular weight triacylglycerols in the oil. These results were in agreement with previous research [ 8 ]. The seed oil contained 3.790% unsaponifiable matter, which was higher than the 1% unsaponifiable matter standard suggested by Fontanel [ 35 ].…”

“…Fenugreek seed oil (mainly of unsaturated acids, namely linoleic, linolenic, and oleic acid) [ 7 ], is used in flavoring many canned foods and syrups and as an ingredient in soma perfumes [ 6 ]. Schuette et al investigated the fenugreek seed oil obtained by Soxhlet extraction using petroleum ether as a solvent, and a yield of 6.7% was obtained [ 8 ]. Ren et al studied the optimal conditions for the extraction of oil from fenugreek seed by supercritical CO 2 fluids.…”

The occurrence of n-heptadecanoic acid (margaric acid) in hydrogenated mutton fat

“…6F1-61.20) did not depress the melting point. Evidence which precludes these two fractions consisting of equimolecular mixtures of palmnitic and stearic acids is furnished by the data of Schuette & Vogel (1940), Smith (1936) and Francis, Collins & Piper (1937), which indicate a maximum solidification point of about 560 for such a mixture. Margaric acid is reported by Waterman & Bertram (1927) to have a refractive index of n" 1-4319, and this value is similar to that obtained for fractions 02S3LSS…”

Review of literature on fats, oils, and soap for 1940*-Part II

“…Nutr. 19,131) found that in rats on diets deficient in the essential fat acids better growth was obtained when the diet was high in carbohydrates than when it was high in fat. This was attributed to the synthesis from carbohydrates of some of the fat acids necessary for growth.…”

“…Bromophenol blue was used as the indicator. Fachini and Martinenghi ( OIii minerali grassi e saponi 19,86,136) criticized the above method because refined oil could be washed sufficiently to remove the last traces of soap thus causing an error in the test. After Romeo (ibid.…”
