Carcass quality in deer and purchasing prices in comparison with beef carcass quality and purchasing prices were assessed in the research from the bio-economic aspect. Specific gravity of muscle tissue in deer carcass in comparison with specific gravity of cattle carcass component was 13.2% higher and specific gravity of bone tissue was 2.8% higher, but adipose tissue was 16% less. Venison quality was higher than beef quality. In venison when compared with beef a cholesterol level (45.2 mg %) was 31.8 mg % lower, but crude protein content was 2.9% higher (23.4%). Meat quality index was 26.0, which is 8.9 higher than in beef. These indicators characterise venison as a healthy product of higher quality for consumer food in comparison with beef. Purchasing price (LVL 4.21 per kg) of venison carcass in 2009 was 1.6 times higher in comparison with beef carcass purchasing price. Research results lead to the conclusion that deer farming products on the market can be positioned as a high-quality, nutrient-rich food with higher sales price than one of beef.

Marinating is a simple technological treatment used to improve the tenderness and flavour of meat by soaking it in an aqueous solution which is composed of different ingredients. That also increases water brinding capacity of meat, thus reducing cooking losses and improving meat juiciness. The aim of current research was to investigate a degree of preference of marinated roasted venison meat. The red deer (Cervus elaphus) meat samples were obtained from a local farm “Saulstari 1”. The experiments were carried out in the Latvia University of Agriculture, Faculty of Food Technology. Prepared samples were marinated at 4 ± 2 deg C temperature in the refrigerator for 48 ± 1 h. After marinating, venison meat samples were wrapped in aluminium foil, and cooked on a pre-heated double hotplate grill at 200 ± 2 deg C temperature until ready to eat (45 ± 2 min). The cooked hot meat samples were sensory evaluated. The sensory evaluation was carried out by using the nine point hedonic scale – ISO 4121:2003. The sensory evaluation of meat sample with thyme and juniper berries showed that the degree of preference was not so high (approximately – 6.0 points). For the venison meat preliminary treatment mayonnaise and tomato sauce marinades possibly could be recommended for acquiring better sensory properties of ready to eat product.

Venison is well known as a traditional meat type in Europe, and it is lower in calories, cholesterol and fat content than common cuts of beef, pork or lamb. The aim of the current research was to determine physico-chemical parameters such protein, fat, pH, moisture content as well microbiological quality of pickled venison during storage. Beef as a control was analyzed for comparison of obtained results. The meat (2×3×2 cm) pieces were pickled in vinegar marinade (composition: tomato sauce, mayonnaise, vinegar, lemon, onion, parsley, paprika, basil, black pepper, rosemary, salt) at 4±2 °C temperature for 48±1 h. The marinated meat was placed in polypropylene trays and hermetically sealed with high barrier polymer film under modified atmosphere (C02 40%+N2 60%) without and with iron-based oxygen scavenger sachets (Mitsubishi Gas Chemical Europe Ageless®). As a control, packaging in air ambiance packed pickled products was used. During storage time, the moisture and protein values significantly (p is less than 0.05) decreased and pH, fat content and colony forming units significantly (p is less than 0.05) increased in the pickled venison samples of all packages. Slower changes in pH of pickled venison and in the protein and moisture content of marinated beef were observed in modified atmosphere with oxygen scavenger during storage.
