Comparison of proximate data among traditional foods from Black Sea Area countries per food group

Introduction. Traditional foods from 6 Black Sea Area Countries (Bulgaria, Georgia, Romania, Russian Federation, Turkey and Ukraine) were prioritized within the frame of the European Project BaSeFood (Sustainable Exploitation of Bioactive Components Black Sea Area traditional foods). The selected traditional foods were categorized into 6 food groups: 1) Cereal or cereal based foods; 2) Fruit or fruit based foods; 3) Vegetable or vegetable based foods; 4) Oilseeds or oilseed products; 5) Herbs, spices and aromatic plants; and 6) Low or non-alcoholic fermented products. One of the aims within BaSeFood project was to produce an overview of the nutritional value of each traditional food and compare it among the categorized food groups. Material and methods. The 33 selected traditional foods were prepared according to a recorded traditional recipe, ingredients and traditional preparation methods. The following components were determined: moisture, ash, total nitrogen (for protein), total fat, individual fatty acids, starch, total sugars and dietary fibre for each food. Results. Our results show that vegetables and vegetable based foods; herbs, spices and aromatic plants; and low or non-alcoholic fermented foods and beverages of plant origin were the food groups with the lower energy content mainly due to its high water content (>60.0 g/100 g). Oilseeds or oilseed products were the group that presented the highest mean content of ash (2.23 g/100 g), total protein (15.9 g/100 g) and total fat (72.0 g/100 g). Sour rye bread, which belongs to the cereals and cereal based foods group, contained the highest starch content (66.3  0.55 g/100 g). The highest total sugars content (85.3  0.30 g/100 g) was found in rose jam, a food from the fruit or fruit based foods group. All results are given per 100 g of edible portion. Conclusions. The proximate composition of the selected traditional foods from Black Sea Area countries is important in order to elucidate their role in the dietary pattern of populations and will be useful to include new nutritional data in national food composition databases.
