Abstract

The mechanically deboned meat (MDM) is a product made by trituration of some parts of slaughter animals’s carcass that are not easy to separate the bone. In such case the mild meat is deboned by especial equipment. As a result of technological modernization, the MDM has been more frequently used due to its easy obtainment and transformation in industrialized food products. The physical-chemical quality of MDM affects directly the quality of processed food in which MDM takes part. Twenty samples of mechanically deboned poultry meat were collected in two different slaughterhouse and 20 samples of mechanically deboned bovine meat commercialized in Goias State were also collected. The analyses performed were: calcium, iron, zinc, total lipid, protein, moisture, fixed mineral residue, peroxid index, cadmium and lead contents. The metodologies applied in the analysis were based on official methods. The results revealed that samples were within the official limits. The MDM did not show rancidity by peroxide rate; moisture and ashes were within the expected for meat. The MDM can be part of a food diet as source of protein, lipid, calcium, zinc and iron, once the iron was more frequently found as heme iron, which has a high bioavailability. The content of lead and cadmium were under the allowed limits. In this manner, we can observe the importance of the physical-chemical evaluation of MDM, controlled by official organs.

KEY WORDS: Atomic absorption spectrometry, contaminants, iron, mechanically deboned meat, zinc.
