Abstract:
The quantitative identification possibility feasibility of commercial animal meat treated with ionizing radiation has a practical focus on monitoring the irradiated products market. According to the results of the conducted studies, the authors revealed high efficiency of using the electron paramagnetic resonance (EPR) method to determine the absorbed radiation doses for different types of bone tissue, in contrast to the requirements of the GOST R 52529-2006 “Meat and Meat Products. Electronic Paramagnetic Resonance Method for the Detection of Radiation-Treated Meat and Meat Products Containing Bone Tissue”, namely: tubular tibia and flat scapula with a high degree of reliability from 0.5–0.4 kGr to 5.5–5.1 kGr when irradiated with doses of 3–11 kGr. According to the organoleptic assessment, a man took an indicator of 9-10 kGy as the optimal dose of ionizing radiation. In the samples of roe deer bone tissue, the absorbed dose is in the range from 3.2–3.5 kGy to 4.1–4.4 kGy, which meets the safety requirements according to the Codex Alimentarius. Safety assessment of raw meat obtained from commercial animals, in particular roe deer living in the natural conditions of the Trans-Urals (East Ural radioactive trace), shows that the specific activity of Cs-137 meets the requirements of the SanPiN 2.3.2.1078-01 “Hygienic Requirements for the Safety and Nutritional Value of Food Products” and is equal to 65 ± 5 Bq/kg. As a result of a comprehensive assessment of organoleptic, oxidative spoilage, microbiological indicators, of toxic elements and radionuclides amount (Cs-137), the researchers reveales that the chilled meat of commercial slaughtered roe deer (half-carcasses were treated with different radiation doses) during the storage period of up to 16 days meets technical regulations requirements. Determining the optimal doses of ionizing radiation for processing valuable meat raw materials of commercial slaughtered roe deer will ensure high quality of meat during the storage.
