title: The effect of meat cuts and thermal processing on selected mineral concentration in beef from Holstein-Friesian bulls.
abstract: The impact of meat cuts (nine muscles and liver) and thermal processing on selected mineral (potassium, sodium, phosphorus, magnesium, zinc, iron, including heme form) concentration in beef from Holstein-Friesian bulls was evaluated in the present study. The mineral's content widely varied depending on the tissue type (skeletal muscles/liver, except zinc) and between the different bovine muscles. The greatest diversity between the muscles demonstrated was zinc (3.5-6.9 mg 100 g(-1)f/w) and iron (1.7-2.3 mg 100 g(-1)f/w), however, there were no significant differences in heme iron to total iron ratio (average 74%). Thermal processes conducted on longissimus dorsi muscles also significantly affected mineral concentration. Grilled, roasted and fried bovine meat was characterised by a higher content (by 6-26%) of most studied minerals (except sodium) as compared to raw meat. Sodium levels in processed meat were 16-33% lower than in raw samples.
