- Opis:
- As well as having the information about the nutritional value of raw meat, today’s consumers expect to be informed to what extent cooked meat meals satisfy recommended nutrition standards. The aim of the study was to estimate the degree to which the demand for selected macrominerals (K, Na, Mg, Ca) and microminerals (Zn, Fe, Mn, Cu) by adults and children is met by a portion of 100 g of cooked beef. For calculations, the average cooking loss at 40% and retention factors between 0.85 and 1.0 were taken into consideration. The degree of satisfying Polish nutrition standards (Recommended Dietary Allowance – RDA and Adequate Intake – AI) was analysed depending on a muscle (longissimus lumborum – LL vs. semitendinosus – ST) and breed of young bulls (Polish Red – PR, Whitebacked – WB, Polish Black-and-White – PBW, Simmental – SIM and Polish Holstein-Fresian – PHF). Among the evaluated cattle breeds, the meat of PHF bulls met to the greatest degree the recommended dietary allowance (RDA) for Zn, Fe and Mn, and to the smallest degree the daily requirement for K and Mg. The LL and ST muscles satisfied the nutritional standards for major minerals to a similar degree, and were primarily (especially the LL muscle) a good source of Zn and Fe (for adults and children), as well as a source of K, Mg and Cu for children. Consumption of 100 g of cooked meat (depending on the breed) satisfied from 52% to 85% of the RDA for Zn for women, 38-62% for men and as much as 83-136% for children. For Fe, the percentages were 14-20% for women and 26-36% both for men and children. Cooked beef was an important source of Mg, particularly for children, as a portion of 100 g met from 27% to 35% of their RDA. However, the same portion met only 3-5% of the daily standard for Na for adults and 4-6% for children.
