W artykule omówiono alternatywne źródła białka zwierzęcego. Mięso może pochodzić nie tylko od zwierząt hodowlanych (bydło, trzoda chlewna i drób), ale także od zwierząt egzotycznych. Podróże po świecie, otwarcie granic i import do Polski nowych rodzajów mięsa sprawiają, że konsumenci mogą skosztować mięsa strusia, kangura, czy rodzimego bobra, a nie tylko krajową dziczyzną.

Present work shows alternative sources of animal proteins. Meat can come from farm animals (cattle. pigs and poultry) as well as from quite new exotic sources. Travelling, opened borders and import of new kinds of meal give the opportunity for consumers to taste the ostrich, kangaroo or the native beaver meat and addition to national venison.

The objective of this study was to evaluate the color of unpackaged and vacuum-packaged venison during storage. Color parameters L*, a* and b* were assessed in vacuum-packaged samples after 72, 144, 216, 288 and 360 h of storage, and in unpackaged samples – after 72, 144 and 216 h. The total change in color ΔE* in comparison with the color of fresh meat was determined. The results indicate that the storage of unpackaged venison has an adverse effect on color, giving it a darker, grayish hue. The most profound changes were observed after 144 and 216 h of storage. Vacuum packaging of venison minimizes color change and has a long-term stabilizing effect for up to 15 days.

W pracy oceniano barwę niepakowanego i pakowanego próżniowo mięsa jelenia podczas przechowywania. Oznaczenie parametrów barwy L*, a*, b* wykonano w próbkach pakowanych próżniowo po 72, 144, 216, 288, 360 h przechowywania, zaś w niepakowanych po 72, 144, 216 h. Wyliczono również całkowitą zmianę barwy ΔE* w stosunku do barwy mięsa świeżego. Wykazano, że przechowywanie mięsa jelenia bez opakowania zmienia niekorzystnie jego barwę, powodując ciemnienie i szarzenie. Zmiany miały największy zakres po 144 i 216 h przechowywania. Przechowywanie mięsa tego gatunku w opakowaniu próżniowym zmniejsza zakres zmian barwy, działając stabilizująco w długim okresie (do 15 dni).

W pracy oceniano cechy hydratacyjne (nie pakowanego i pakowanego próżniowo) mięsa jelenia podczas przechowywania. Przechowywanie mięsa poprawia większość badanych cech, najszybciej następuje poprawa zdolności utrzymywania wody dodanej, następnie obniża się wyciek cieplny i woda wolna. Sposób pakowania mięsa wpływa na zawartość wody wolnej.

Hydration properties of unpacked and vacuum packed deer meat were investigated in the paper. Storage of meat improves most of the evaluated properties, firstly water holding capacity is improved, then thermal drip and free water are reduced. The way of packaging of meat affects free water content.

Projectiles made of lead alloys are used for waterfowl hunting in Europe. The paper demonstrated that lead pellets, due to their construction and use, contaminate the environment, especially water ecosystems. During one hunting session, tens of thousands of lead balls are introduced to the environment. Moreover, dispersed heavy metal is ingested by birds as gastroliths; as a result, game birds as well as protected birds become intoxicated with lead. During hunting trips, birds are also injured. When entering into the food chain, lead from pellets poses a risk to many living organisms, including predators and scavengers. Injured or intoxicated birds have difficulty joining seasonal migrations. Meat, especially of wild ducks and geese, is consumed during the hunting season by hunters and their families. Considering the level of lead in the muscles of game birds, venison consumers are also exposed to lead intoxication. In Europe, an increasing number of hunters who use lead pellets has resulted in lead being accumulated in game birds, which is a hazard to the public health. In view of the above facts and other hazards resulting from hunting, which endanger humans and animals, the authors recommend a total ban on waterfowl hunting.

Cadmium and lead were determined in the tissues of roe buck from the Polesie Lubelskie region using atomic absorption spectrometry (AAS). The determinations involved muscles, hearts, kidneys and livers. The samples were mineralized in the muffle furnace at 450°C. The content of the elements was determined after extraction to organic phase (4-methylpentan-2-one, MIBK) of its complex with ammonium pyrrolidindithiocarbamate (APDA). The highest levels of the examined metals were detected in kidneys (1.11mg/kg-Cd and 0.304mg/kg- Pb) and livers (0.577mg/kg-Cd and 0.184mg/kg-Pb); the lowest ones in muscles (0.035mg/kg-Cd and 0.200mg/kg-Pb).
