REVIEW
C Fanali, G Micalizzi, P Dugo, L Mondello
The present paper provides an overview of the application of ionic liquid (IL) columns for GC analysis of fatty acid methyl esters (FAMEs). Although their separation can be carried out utilizing GC columns containing polar stationary phases, some ILs have been employed as stationary phases, either commercial or laboratory made, in GC analysis. Monodimensional and bidimensional GC methods have been optimized in order to achieve the best separation especially considering the geometric and positional isomers of unsaturated fatty acids...

The prevalence of nonalcoholic fatty liver disease (NAFLD) has dramatically increased globally during recent decades. Intake of n-3 polyunsaturated fatty acids (PUFAs), mainly eicosapentaenoic acid (EPA, C20:5n-3) and docosahexaenoic acid (DHA, C22:6n-3), is believed to be beneficial to the development of NAFLD. However, little information is available with regard to the effect of flaxseed oil rich in α-linolenic acid (ALA, C18:3n-3), a plant-derived n-3 PUFA, in improving NAFLD. This study was to gain the effect of flaxseed oil on NAFLD and further investigate the underlying mechanisms...

Although there is accumulating evidence for a protective role of n-3 polyunsaturated fatty acids (n-3 PUFAs) on bone health, there are limited studies that examine the effect of altering dietary n-6:n-3 PUFA ratio with plant and marine sources of n-3 PUFA on bone health. Healthy adults (n = 24) were randomized into an eight-week crossover study with a four-week washout between treatments, with each subject consuming three of four diets. The four diets differed in the dietary n-6:n-3 PUFA ratios and either had an algal oil supplement added or not: (Control diet (10:1); α-linolenic acid (ALA) diet (2:1); Eicosapentaenoic acid/Docosahexaenoic acid (EPA/DHA) diet (10:1 plus supplement (S) containing EPA/DHA; Combination diet (2:1 + S))...

N3 FA promote beneficial effects on cardiovascular diseases, but they are highly susceptible to oxidation, which leads to the formation of potentially toxic secondary products. In this study, the antioxidant capacity of natural compounds (sinapic acid and rutin) was evaluated using an accelerated model to oxidize the oils. Five inducers (Temperature, Fe(2+) , AAPH, Ascorbyl palmitate and AMVN) were combined in a factorial design to accelerate the oxidation of three oils (flaxseed, echium and fish) containing different sources of n3 FA...

Emerging evidence suggests that higher circulating long-chain n-3 polyunsaturated fatty acids (n-3PUFA) levels were intimately associated with lower prevalence of obesity and insulin resistance. However, the understanding of bioactivity and potential mechanism of α-linolenic acid-rich flaxseed oil (ALA-FO) against insulin resistance was still limited. This study evaluated the effect of FO on high-fat diet (HFD)-induced insulin resistance in C57BL/6J mice focused on adipose tissue lipolysis. Mice after HFD feeding for 16 weeks (60% fat-derived calories) exhibited systemic insulin resistance, which was greatly attenuated by medium dose of FO (M-FO), paralleling with differential accumulation of ALA and its n-3 derivatives across serum lipid fractions...

The aim of the work is to compare the antioxidant activity of 4-vinylguaiacol (4-VQ) and 4-vinylsyringol (4-VS) added to stabilize three (flaxseed, olive and rapeseed) commercial oils. The phenolics were added at concentration of 20, 40 and 80mg per 100g of oil. The oils were oxidized in a Rancimat test at 110°C. The linear dependences between the concentrations of each of these compounds and the induction period (IP) were found. Generally, 4-VQ was more effective, since the determined IP increase after its addition was from 5 to 25-fold higher than for the same addition of 4-VS...

Consumption of α-linolenic acid (ALA)-rich flaxseed oil is a possible way to supplement ω-3 polyunsaturated fatty acids, but the beneficial effects to cardiovascular systems are still controversial. In this study, human umbilical vein endothelial cells (HUVECs) treated with 100 ng/mL lipopolysaccharide (LPS) were used as the in vitro model and the potential beneficial effects of well-characterized flaxseed oil and ALA were studied. Exposure of HUVECs to LPS for 24 h significantly promoted inflammatory response as release of interleukin 6 (IL-6), soluble intercellular cell adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule 1 (sVCAM-1) as well as adhesion of THP-1 monocytes, but did not induce cytotoxicity or oxidative stress...

Carefully designed delivery systems are required to encapsulate and protect omega-3 fatty acids in commercial food and beverage products, but then release them at the required site-of-action within the human gastrointestinal tract (GIT). Previously, we showed that the oxidative stability of flaxseed oil (a plant-based source of omega-3 fatty acids) encapsulated in nanoemulsion droplets or calcium alginate microgels (hydrogel beads) was improved using caseinate as a natural antioxidant. In this study, the impact of caseinate on the digestion of flaxseed oil encapsulated in these delivery systems was investigated using a simulated GIT...

Holstein-Friesian steer beef production is renowned globally as a secondary product of the milk industry. Grass feeding is a common practice in raising Holstein steers because of its low cost. Furthermore, grass feeding is an alternative way to produce beef with a balanced n-6 to n-3 fatty acids (FAs) ratio. However, the performance and meat quality of Holstein-Friesian cattle is more likely to depend on a high-quality diet. The aim of this study was to observe whether feeding two mixed diets; a corn-based total mixed ration (TMR) with winter ryegrass (Lolium perenne) or flaxseed oil-supplemented pellets with reed canary grass haylage (n-3 mix) provided benefits on carcass weight, meat quality and FA composition compared with cattle fed with reed canary grass (Phalaris arundinacea) haylage alone...
