Abstract Microalgae and microalgae-derived ingredients are one of the top trends in food industry. However, consumers’ acceptance purchase intention a product will be largely affected by odour flavour. Surprisingly, scientific literature present very limited number studies on volatile composition microalgae cyanobacteria. In order to fill gap, main objective study was elucidate seven microalgal cyanobacterial strains from marine freshwaters, with interest for industry while establishing its...
Abstract Muskox ( Ovibos moschatus ) are ruminant animals native to the far north and little is known about their fatty acid composition. Subcutaneous adipose tissue (backfat) from 16 wild muskox was analyzed compared backfat barley fed beef cattle. composition differed substantially most striking difference a high content of 18:0 (26.8 vs. 9.77%). This accompanied by higher levels other saturated acids except had more 16:0. also lower level cis ‐18:1 this related expression steroyl‐CoA...
Adverse health effect of trans fatty acids (TFAs) are well recognized, which has precipitated efforts to reduce their content in food products. With the decline dietary TFAs derived from partial oil hydrogenation, interest is focused on remaining sources ruminants (rTFA), deodorized vegetable oils, isomerization during frying, and synthetic conjugated FA (CFA) supplements. Partial hydrogenation heat‐treated oils result a random distribution TFA isomers, whereas rTFAs contain specific isomers...
Abstract Conjugated linoleic acid ( c 9, t 11 CLA) is a dietary fatty produced mainly by ruminant animals and exhibits promising health‐promoting biological effects. For lipid composition analyses, including CLA, lipids must be pre‐treated so that the free esterified acids (triacylglycerols, phospholipids, etc) are available for determination. The most common treatments involve methyl ester derivatives from relatively simple chemical reactions, but this becomes complicated when...
A survey of Canadian retail beef was undertaken with emphasis on the trans fatty acid (TFA) and conjugated linoleic (CLA) isomers, compared current health recommendations. Thirty striploin steaks were collected in winter summer from major grocery stores Calgary (Alberta, Canada). Steak compositions (backfat longissimus lumborum muscle analysed separately) showed minor seasonal differences lower total saturates (P < 0.05) higher monounsaturates 0.01) winter, but no polyunsaturated acids....
Intensively finishing cattle on a high-grain diet is generally used to enhance marbling, whereas extensively grass known provide improved muscle fatty acid profiles. The objective of this study was evaluate what extent intensive concentrate (0, 1 or 2 months) can be combined with forage feeding without negatively affecting the profile genetically lean animals. Bulls from 'Asturiana de los Valles' breed were reared under grazing conditions with/without final barley-based concentrate: 0 months...
Summary Two previously reported non‐synonymous coding single nucleotide polymorphisms (SNPs) of bovine stearoyl‐CoA desaturase (delta‐9‐desaturase) ( SCD ) (c.878C>T) and fatty acid synthase FASN (g:17924A>G) were assessed for their associations with 72 individual 12 groups acids in brisket adipose tissue 223 Canadian commercial cross‐bred beef steers. It was found that the ‘CC’ genotype SNP significantly associated lower concentrations saturated (SFA) including 10:0, 14:0 20:0, higher...

Sci. 91: 545–556.Trans acids are found naturally in foods, particularly those derived from ruminant animals, such as dairy cattle. Over the past few decades, human consumption of trans has increased, but this been mainly products containing partially hydrogenated vegetable oils. The correlation with diseases coronary heart disease...
A study was conducted on crossbred steers (n = 275; 376 ± 24 kg) to evaluate performance and carcass quality of cattle fed wheat or corn dried distillers’ grains with solubles (DDGS). The control ration contained 86.6% rolled barley grain, 5.7% supplement 7.7% silage (DM basis). four treatments included replacement grain at 20 40% the diet basis) DDGS. Steers were slaughtered a common end weight 645 kg 100 randomly per treatment) selected for determination retail yield sub-primal boneless...
