Microencapsulated flaxseed oil powder (MFOP) was supplemented for the fortification of α-linolenic acid (ALA, ω-3 fatty acid) in ice cream. Processing parameters were optimized in terms of the stage of homogenization of ice-cream mix, level of fortification (3, 4 and 5%) and flavors (vanilla, butter scotch and strawberry). Data revealed that free fatty acids increased significantly during first 15 days in all the samples and then remained constant. Peroxide value and thiobarbituric acid value first increased up to 30 and 45 days, respectively; and then decreased followed by a gradual increase up to 120 days...

The spin ability of flaxseed mucilage (FM) as a new source was evaluated through electrospinning. At various experimental conditions and different solution properties, it was impossible to fabricate FM nanofiber. Thus, polyvinyl alcohol (PVA) was applied as co-polymer to facilitate nanofiber formation. In terms of morphology, FM:polyvinyl alcohol (PVA) nanofiber using a mixture of 3% FM solution and 12% (PVA) solution at ratio of 60:40 was selected as the best sample. The physicochemical properties of the nanofiber was evaluated by scanning electron microscopy (SEM), fourier transform infrared (FTIR), differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA) and X-ray diffraction (XRD)...

Chickens can hepatically synthesize eicosapentaenoic acid (20:5 n-3) and docosahexaenoic acid (22:6 n-3) from α-linolenic acid (ALA; 18:3 n-3); however, the process is inefficient and competitively inhibited by dietary linoleic acid (LNA; 18:2 n-6). In the present study, the influence of dietary high-oleic acid (OLA; 18:1 n-9) soybean oil (HOSO) on egg and tissue deposition of ALA and n-3 polyunsaturated fatty acids (PUFA) synthesized from dietary ALA was investigated in laying hens fed a reduced-LNA base diet supplemented with high-ALA flaxseed oil (FLAX)...

Myocardial cell apoptosis mediated by oxidative stress has previously been identified as a key process in ischemic heart disease. Secoisolariciresinol diglucoside (SDG), a polyphenolic plant lignan primarily found in flaxseed, has been demonstrated to effectively protect myocardial cells from apoptosis. In the present study, the role of the Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) was investigated in mediating the protective effect of SDG. Findings of the present study revealed that treatment with H2O2 reduced cell viability and induced apoptosis in H9C2 rat cardiomyocytes...

Sodium valproate (VPA) is an anti-epileptic drug, but has a strong embryotoxicity due to its induced disturbance of folate-homocysteine (Hcy) metabolism and fatty acid metabolism. The aim of the present study was to investigate whether polyunsaturated fatty acid (PUFA) intake during pregnancy can relieve the embryotoxicity of VPA. VPA (dose: 500 mg kg-1, concentration: 38.5 mg ml-1) was intraperitoneally injected into pregnant mice on day 8.5 of gestation (E8.5d). PUFA intake significantly decreased fetal mortality and NTD incidence induced by VPA: n-3 long chain PUFAs (n-3 LCPUFAs) in fish oil had the best decreasing effect, followed by C18:3n-3 in flaxseed oil and then C18:2n-6 in corn oil...

Functional foods can be effective in the prevention of metabolic syndrome and subsequently the onset of cardiovascular diseases and type II diabetes mellitus. More recently, however, another term was introduced to describe foods with additional health benefits: "superfoods", for which, to date, no generally accepted definition exists. Nonetheless, their consumption might contribute to the prevention of metabolic syndrome, for example due to the presence of potentially bioactive compounds. This review provides an overview of controlled human intervention studies with foods described as "superfoods" and their effects on metabolic syndrome parameters...
