“…It was reported that these fatty acid affect the biohydrogenation of C18:2n-6 and C18:3n-3 fatty acids in the rumen. LC-PUFA inhibit the step of hydrogenation from trans C18:1 to C18:0 causing higher level of trans C18:1 fatty acids, and other specific biohydrogenation intermediates have been associated with milk fat depression and negatively influenced protozoa and cellulolytic bacteria inhabiting in rumen (Toral et al, 2017;Białek et al, 2018b). In the present study, the effect of 15 g/head/ day marine algae supplementation on rumen viability and fermentation was not so unequivocal; marine algae feeding elevated fat content of milk and concentrations of small and medium chained fatty acids (e.g., C8:0 and C10:0) of milk.…”

“…Prior to chromatographic analyses, FA were derivatized by the base-and acid-catalyzed methylation procedures [47] and then quantified using gas chromatograph coupled with mass spectrometer (Shimadzu GC-MS-QP2010 Plus EI, Tokyo, Japan); chromatographic system was equipped with a BPX70 fused silica column (120 m × 0.25 mm i.d. × 0.25 µm film thickness; Phenomenex, Torrance, CA, USA), a quadruple mass selective detector (Model 5973N, Shimadzu, Tokyo, Japan) and an injection port [48]. Nonadecanoic acid (99%, Sigma, St. Louis, MO, USA) was used as the internal standard (IS).…”

The number of different types of cheese worldwide exceeds 4000 and dairy fat, composed of about 400 fatty acids (FA), is one of the most complex dietary fats. Cheeses are valuable sources of different bioactive FA, i.e., conjugated FA (CFA). The aim of present study was to determine FA profile of commercially available ripening cheeses, with the special emphasis on CFA profile. Multivariate analyses (cluster analysis (CA), principal component Analysis (PCA), and linear discriminant analysis (LDA)) of chromatographic data have been proposed as an objective approach for evaluation and data interpretation. CA enabled the differentiation of ripening cheeses from fresh cheeses and processed cheeses. PCA allowed to differentiate some types of ripening cheese whereas proposed LDA model, based on 22 analyzed FA, enabled assessing cheeses type with average predictive sensitivities of 86.5%. Results of present study clearly demonstrated that FA and CFA content may not only contribute to overall nutritional characteristics of cheese but also, when coupled with chemometric techniques, may be used as chemical biomarkers for assessing the origin and/or the type of ripening cheeses and the confirmation of their authenticity, which is of utmost importance for consumers.

“…Prior to the chromatographic analysis, hearts were subjected to alkaline hydrolysis. In order to determine CFAs (dienes, CD, and trienes, CT), Waters HPLC 625LC system (Milford, MA, USA), four ion-exchange columns loaded with silver ions (Chromspher Lipids 5 µm, 250 × 4.6 mm; Varian, The Netherlands) and a photodiode array detector (PDA) were used [42,43]. The FA profile was determined as methyl esters with the addition of nonadecanoic acid (C19:0) as the internal standard (IS).…”

Linking the early life environment with later health status is known as “developmental programming”. This study aimed to assess whether the introduction of conjugated linoleic acids (CLAs) into the maternal diet affects the content fatty acids (FAs), conjugated FAs (CFAs), cholesterol, oxysterols, malondialdehyde (MDA) and tocopherols in the hearts of their female offspring treated with 7,12-dimethylbenz[a]anthracene and if offspring supplementation enhanced the effect of maternal supplementation. FA, cholesterol and oxysterol contents were determined by gas chromatography-mass spectrometry, while contents of CFAs and MDA were determined by high-performance liquid chromatography (HPLC) with photodiode detection. The supplementation of mothers with CLAs significantly decreased the amount of atherogenic saturated FAs and enhanced the level of eicosapentaenoic FA in the hearts of offspring. Continuous progeny supplementation decreased the content of arachidonic acid in hearts. Supplementation of the maternal diet with CLAs and its continuation during the postnatal period increased the ratio of hypo to hypercholesterolemic FAs. Significantly fewer oxysterols were detected in the hearts of progeny of dams fed with CLAs as compared to the offspring of mothers receiving safflower oil. Both fetal and postnatal CLA intake significantly reduced 7β-hydroxycholesterol accumulation. It can be concluded that CLA supplementation during the fetal and postnatal period may be an effective method of maintaining the cardiac health status of newborns.
