M.I. Pop, Gabriela Frunză

Abstract
    The purpose of this study was a comparative analysis of the nutritional-economic characteristics of fresh minced meat rolls, marketed under its own brand in the main supermarkets in Romania (Auchan, Billa, Carrefour, Kaufland, Lidl), and respectively produced and marketed of a local butchery. There were analyzed 36 samples (purchased in June 2017), based on the ingredients and additives used, but also of the chemical composition, of the energy value and the price of products, using both, the information on the labels and also the results of the own determinations. The content of proteins, lipids, collagen and water was determined using the automatic analyzer Food Check (infrared spectrophotometer); the mineral substances were determined by calcination and the carbohydrates and energy value were determined by calculation, using conventional formulas. The data obtained were statistically processed, including by analysis of variance, with significant and very significant differences for the most parameters analyzed (differences that can be attributed to different manufacturing recipes respectively of the raw material and the chemical composition). The most important differences between the products analyzed have targeted the lipid content (up to 111.6 g/kg of product), water (up to 97.7 g/kg product) and the energetic value (up to 893 kcal/kg of product) but also for protein content (up to 24.4 g/kg of product).
