Lipid stability and meat colour of beef from pasture- and grain-fed cattle with or without vitamin E supplement

Influence of vacuum-ageing duration of whole beef on retail shelf life of steaks packaged with oregano (Origanum vulgare L.) active film under high O2

“…Popova et al (2009) reported that ageing under vacuum for 14 days affected lipid oxidation of beef throughout storage since it was more intense than in the control, being the difference in TBA-RS significant (p \ 0.05) on the 1st and the 6th days of storage. Yang et al (2002) found no effect of beef vacuum-ageing for 47 days on initial TBA-RS values under aerobic storage compared with no aged beef. However, after 7 days of aerobic storage, TBA-RS of aged beef increased significantly while the increase in non-aged beef was small.…”

Carcass- and meat quality of pasture <i>vs</i> concentrate fed German Simmental and German Holstein bulls

“…Investigation of vitamin E supplementation of pasture-fed cattle showed, that the concentrations in fresh grass may be a good dietary source of α-Tocopherol and can theoretically result in muscle saturation with α-Tocopherol. YANG et al (2002) andSCHWARZ et al (2003) found no further significant accumulation of muscle and liver α-Tocopherol contents during vitamin E supplementation of pasturefed cattle. VESTERGAARD et al (2000) measured a higher proportion of oxidative fibres and a darker meat colour in pasture fed young bulls compared to grain fed animals.…”

“…There are differences in the diet effects on carcass and meat quality if the animals are slaughtered at different ages (same weight, but different growth rates) or at different weights (same age, and different growth rates), (PRIOLO et al, 2001). Grass feeding has reported to affect several carcass and meat quality characteristics, in particular colour and flavour (SCHWARZ et al, 1998;MUIR et al, 1998;PRIOLO et al, 2001;PURCHAS et al, 2002;YANG et al, 2002;LANARI et al, 2002;ARTHUR et al, 2004;HOLLO et al, 2004;SCHNAECKEL et al, 2006). However, FRENCH et al 2000 showed that when steers had a similar mean rate of carcass growth, pre-slaughter diet (autumn grazed grass, concentrates or grass silage) did not affect the sensory perception of meat quality.…”

Effect of beef from grass or maize silage- and concentrate-fed cattle on lipid metabolism and antioxidative status of rats

“…pounds in beef is enhanced by pasture feeding. Compared with nutrition using large amounts of concentrates, it also ensures higher contents of antioxidants such as α-tocopherol or β-carotene (Simonne et al, 1996;Yang et al, 2002;De la Fuente, 2009;Łozicki et al, 2012). Some studies in humans demonstrate the influence of fatty acids, vitamins, trace elements, and other bioactive compounds when administered as dietary supplements on lipid metabolism and antioxidant status (Sies, 1997;McAfee et al, 2011).…”
