“…Mustard oil contains a high concentration of monounsaturated FAs (erucic acid, oleic acid, and (Z)-11-eicosenoic acid) and a relatively high concentration of polyunsaturated FAs (linoleic acid and linolenic acid). The FAs compositions revealed in this article demonstrate quantitative correlations with an investigation by Schwarzinger et al [86]. Interestingly, the mustard oil obtained by the cold press method showed that the oleic acid was the major component, whereas the erucic acid was a minor component [87,88].…”

The fatty acid (FA) compositions of thirty-nine vegetable oils and fats, including nangai nut, pili nut, shea butter, tamanu oil, baobab, sea buckthorn berry, Brazil nut, grape seed, black seed, evening primrose, passion fruit, milk thistle, sunflower, pumpkin seed, sesame, soybean, flax seed, kukui, red raspberry seed, walnut, chia seed, hemp seed, rosehip, almond, avocado, carrot seed, moringa, apricot kernel, camellia seed, macadamia, olive, marula, argan, castor, jojoba, pomegranate seed, medium-chain triglyceride (MCT) coconut, roasted coconut, canola, and mustard oil, were analyzed using gas chromatography–mass spectrometry (GC-MS). Vegetable oils and fats have different profiles in terms of their fatty acid composition, and their major constituents vary significantly. However, we categorized them into different classes based on the percentages of different fatty acids they contain. The saturated fatty acids, such as palmitic acid and stearic acid, and the unsaturated fatty acids, including oleic acid, linoleic acid, and linolenic acid, are the main categories. Among them, roasted coconut oil contained the greatest amount of saturated fatty acids followed by nangai nut (45.61%). Passion fruit oil contained the largest amount of linoleic acid (66.23%), while chia seed oil had the highest content of linolenic acid (58.25%). Oleic acid was exclusively present in camellia seed oil, constituting 78.57% of its composition. Notably, mustard oil had a significant presence of erucic acid (54.32%), while pomegranate seed oil exclusively contained punicic acid (74.77%). Jojoba oil primarily consisted of (Z)-11-eicosenoic acid (29.55%) and (Z)-docos-13-en-1-ol (27.96%). The major constituent in castor oil was ricinoleic acid (89.89%). Compared with other vegetable oils and fats, pili nut oil contained a significant amount of (E)-FA (20.62%), followed by sea buckthorn berry oil with a content of 9.60%. FA compositions from sources may be problematic in the human diet due to no labeling or the absence of essential components. Therefore, consumers must cast an eye over some essential components consumed in their dietary intake.

“…The fatty acid composition was determined after the formation of fatty acid methyl ester (FAME) of RSO by following the published method with a minor modification [ 38 ]. In brief, an aliquot of 30 mg of oil was mixed with 2 mL of 0.5 M sodium methoxide (prepared by dissolving metallic sodium in methanol) in a screw-caped test tube and incubated for 45 min at 60 °C with occasional shaking after every 10 min.…”

“…Subsequently, 70 µL of 1 M methanolic sulfuric acid was added, and the mixture was incubated at 60 °C for an additional 30 min. The FAME was extracted by the addition of 500 µL of n-hexane and 600 µL of sodium chloride, and an aliquot of the hexane phase was subjected to GC-MS analysis, as described previously [ 10 ]. A trace 1300 gas chromatograph coupled to an ISQ 7000 single-quadrupole mass spectrometer with a PTV injector and equipped with a TR-FAME column (60 m × 0.25 mm, 0.25 μm film thickness, all Thermo Scientific, Waltham, MA, USA) was used.…”

Palm oil has a bad reputation due to the exploitation of farmers and the destruction of endangered animal habitats. Therefore, many consumers wish to avoid the use of palm oil. Decorative sugar contains a small amount of palm oil to prevent the sugar from melting on hot bakery products. High-oleic sunflower oil used as a substitute for palm oil was analyzed in this study via multispectral imaging and an electronic nose, two methods suitable for potential large-batch analysis of sugar/oil coatings. Multispectral imaging is a nondestructive method for comparing the wavelength reflections of the surface of a sample. Reference samples enabled the estimation of the quality of unknown samples, which were confirmed via acid value measurements. Additionally, for quality determination, volatile compounds from decorative sugars were measured with an electronic nose. Both applications provide comparable data that provide information about the quality of decorative sugars.
