When laying hen diets are enriched with omega-3 polyunsaturated fatty acids to generate value-added eggs for human consumption markets, concentrations of alpha-linolenic (ALA), eicosapentaenoic (EPA), and docosahexaenoic acids (DHA) in the yolk can reach 250 mg/50 g whole egg. Flaxseed, a rich source of ALA, is commonly used for omega-3 enrichment; however, the impact of dietary flaxseed source (extracted oil vs. milled seed) on fatty acid transfer to egg yolk in laying hens is unknown. Therefore, transfer of ALA, EPA, and DHA into egg yolk from extracted flaxseed oil or milled flaxseed was evaluated in Hy-Line W-36 laying hens over an 8-week feeding period (25 to 33 wk old)...

Antioxidant capacity, nutritional and functional quality of wheat bread supplemented with 1-5% flaxseed hull (FH) were studied. Analyses of the chemically-extractable fraction show that supplementation with 5% of FH increased (compared to control) phenolics content (by 93%), radicals scavenging ability (by 176%) and reducing power (by 220%). Furthermore, phenolic antioxidants were bioaccessible in vitro (samples after simulated digestion). Fortification had no significant influence on rapidly and slowly digestible starch, in vitro starch digestibility and values of expected glycemic index; however, a decrease (up to 8%) of relative proteins digestibility was determined...

Flaxseed (FS) and chia seed (CS) are oilseeds rich in omega-3 fatty acids, which may change meat and milk composition when added to ruminants' diets and may have health benefits for humans. Literature on the effects of CS supplementation on ruminal metabolism is nonexistent. A dual-flow continuous culture fermenter system consisting of 6 fermenters was used to assess the effect of FS and CS supplementation in an alfalfa hay-based diet on ruminal fermentation, nutrient digestibility, microbial protein synthesis, and long-chain fatty acid flow...

Understanding how dietary components alter the healthy baseline colonic microenvironment is important in determining their roles in influencing gut health and gut-associated diseases. Dietary flaxseed (FS) has demonstrated anti-colon cancer effects in numerous rodent models, however, exacerbated acute colonic mucosal injury and inflammation in a colitis model. This study investigates whether FS alters critical aspects of gut health in healthy unchallenged mice, which may help explain some of the divergent effects observed following different gut-associated disease challenges...

Flaxseed is used to fortify bread. In order to reduce cyanogenic glycosides compounds of flaxseed, ground flaxseed was incubated at 30 °C and heated in a kitchen microwave oven. The cyanogenic compounds of flaxseed were reduced to 13.4 %. Treated ground flaxseed was coated with Arabic gum solution containing ascorbic acid and hydrogenated fat and was stored at 25 °C for 80 days in order to prevent oxidation of flaxseed oil. Results showed that oxidation in coated samples was lower than that in control samples and that there was a significant difference between them (p < 0...

Three methods for protection of PUFA against biohydrogenation by ruminal microorganisms were evaluated. In method 1 a blend of ground flaxseed, calcium oxide, and molasses was processed through a dry extruder. In method 2, a blend of ground flaxseed, soybean meal, molasses, and baker's yeast was moistened and prewarmed, allowing enzymes from yeast to produce reducing sugars, and the mixture was subsequently processed through a dry extruder like in method 1. In method 3, ground flaxseed was embedded within a matrix of dolomitic lime hydrate (L-Flaxseed) as a protective barrier against biohydrogenation...

Oxidative stress has previously been shown to play a role in the pathogenesis of diabetes mellitus (DM) and its complications. In the present study, the effects of supplementation with dietary antioxidants, flaxseed and α-tocopherol were investigated in diabetic golden Syrian hamsters fed with a high-fat diet. Thirty-five golden Syrian hamsters were randomly divided into a control group (C) and four diabetic groups (DM, DM + flax, DM + E and DM + Flax + E). The hamsters received four different diets for a 20-week period, as follows: i) Groups C and DM received a high-fat diet (40% energy as fat), deficient in α-linolenic acid (ALA); ii) the DM + Flax group received a high-fat diet enriched with ground flaxseed 15 g/100 g of food, rich in ALA; iii) the DM + E group received a high-fat diet enriched with vitamin E, 40 mg α-tocopherol/100 g of food; and iv) the DM + Flax + E group received a high-fat diet enriched with flaxseed and vitamin E...

To clarify the impact of feeding co-extruded flaxseed on carcass quality and pork palatability, 96 pigs (48 barrows and 48 gilts) were fed three different levels of flaxseed (0%, 5% and 10% of dietary intake) for 76days. Carcass quality and meat quality characteristics of pure loin muscle and ground pork (20% fat) were evaluated. Fat hardness and belly firmness decreased (P<0.001) with increasing co-extruded flaxseed. Pigs fed co-extruded flaxseed levels had higher lean yield (P=0.045) and total lean content (P=0...

Our previous research showed greatest protection to vertebral bone mineral density and strength in ovariectomized (OVX) rats when lignan- and α-linolenic acid-rich flaxseed (FS) is combined with low-dose estrogen therapy (LD) compared with either treatment alone. This study determined the effects of combined FS+LD on serum and tissue markers of bone turnover and microarchitecture to explain our previous findings. Three-month-old OVX rats were randomized to negative control (NEG), FS, LD or FS+LD for 2 or 12 weeks, meaningful time points for determining effects on markers of bone metabolism and bone structure, respectively...

A serial slaughter study, involving 45 individually housed Yorkshire female pigs, was conducted to evaluate the impact of feeding diets containing ground flaxseed (FS) during either the grower or late finisher phase on the incorporation of α-linolenic acid (18:3n-3) and n-3 highly unsaturated fatty acid metabolites (n-3 HUFA; all n-3 PUFA excluding 18:3n-3) in trimmed loin (longissimus dorsi) and belly (cross-section cut). Growth performance, carcass characteristics, and pork quality were also monitored. The three feeding regimens were 1) feeding a diet containing 10% FS between 25 and 50 kg BW, followed by FS-free diets (low n-3 PUFA content) until 110 kg BW (FS early, FSE; n = 16), 2) feeding no FS diets between 25 and 85 kg BW, followed by a diet containing 6% FS until 110 kg BW (FS late, FSL; n = 17), and 3) feeding FS-free diets between 25 and 110 kg BW (CON; n = 8)...
