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.

Today the demand for plant-based protein is growing rapidly due to increased awareness of animal protein growing costs and limited supply and has been highly related to biodiversity loss, climate change, and freshwater depletion. Legumes are in demand for their high content of protein, minerals, vitamins, and carbohydrates, also including dietary fibre. Legumes are rich not only in macronutrients and micronutrients but also contain anti-nutritional factors. One of the most important anti-nutritive properties of legumes is their high trypsin activity. The length of time required for the preparation of legumes has limited their frequency of use compared to recommended intake levels. By heat treatment, an anti-nutritional component in legumes can be mostly separated. The possibility of using extrusion cooking, microwave dryer, roasting equipment, etc., is widely studied. Roasting is one of the widespread methods for treatment of legumes that significantly enhances the texture, flavour, colour, and product appearance. The latest studies in the legume treatments report valuable results after the combined treatments, wet roasting, which includes: dehulling, soaking, and roasting. Heat treatment can be a potential way to improve legumes use in food production: reducing the time required for treatment, preparation and improving nutritional value. l
