“…Moreover, the percentage of intramuscular fat (IM fat area/muscle area) from the young Holstein of the current study ranged around 3.6% (C, 3.37%; L, 3.73%; CLA, 3.52; L+CLA, 3.73%; P>0.05) (Albertí et al, 2013).…”

“…However, the higher proportion of PUFA in the IM than the SC tissue could be partly attributable to the fact that the membrane/cytoplasm relation is lower in the IM tissue because the adipocytes size was lower in the IM tissue (Albertí et al, 2013), as well as membrane phospholipids in the IM tissue show higher proportion of PUFA (Raes et al, 2004).…”

Instrumental assessments and sensory tests were performed to evaluate the effects of diet and postmortem ageing time (1, 7 and 21 days) on beef quality. A total of 48 Friesian calves were randomly allocated to four dietary treatments: control, whole linseed (10% linseed), conjugated linoleic acid (CLA) (2% protected CLA), and whole linseed + CLA (10% linseed and 2% protected CLA). Animals were slaughtered at 458 ± 16.6 kg live weight and 11 months of age. Ageing was more significant than diet on most instrumental parameters. Meat from linseed enriched diets had greater drip loss ( P ⩽ 0.001) and intramuscular fat ( P ⩽ 0.01) than meat from animals fed CLA. Beef aged for 7 and 21 days had lower cooking losses ( P ⩽ 0.01) and shear force ( P ⩽ 0.001) than beef aged for 1 day. Lightness was affected only by display time. The addition of CLA in the diet increased hue and yellowness, whereas the inclusion of linseed decreased these values, as well as increased redness. Linseed in the diet decreased fat odour ( P ⩽ 0.05), but increased beef ( P ⩽ 0.01) and liver ( P ⩽ 0.05) flavours. Meat aged for 21 days was significantly more rancid ( P ⩽ 0.001), even under vacuum storage. Several organoleptic properties were improved with the inclusion of linseed in the diet, whereas they remained unaffected by the inclusion of CLA.

The shelf life and oxidative stability of refrigerated raw ground beef enriched with omega‐3 and/or conjugated linoleic acid (CLA) were studied. Grape seed extract (GSE) was used to inhibit lipid oxidation in the ground beef. Eight treatments of ground beef were established according to the enrichment of beef (control, enriched with omega‐3, with CLA, or with omega‐3 plus CLA) and the use of GSE (0 and 250 mg GSE/kg product). Fresh beef was ground and mixed with GSE and salt. Treatments of beef were stored at 2 ± 1°C in aerobic packaging for 0, 1, 3, and 6 days under retail display conditions. Oxidation stability (thiobarbituric acid‐reactive substances [TBARS]), pH, instrumental color, metmyoglobin formation, and sensory attributes (color and odor) were measured. Omega‐3‐enriched beef increased the oxidation level at day 6 as determined by TBARS (P < 0.05), but the instrumental color was not affected. The enrichment of CLA improved the coordinates of color (P < 0.05) until day 3 and decreased the oxidation at day 6 (P < 0.05). There were no differences in color and odor values among the types of beef during display, except at day 3, when CLA treatments had the highest scores. Addition of GSE decreased the oxidation level (P < 0.001) and did not affect the instrumental color or the sensory parameters.
