Gluten is a vegetable protein, which, due to its properties, is very often used in various sectors of the food industry and therefore in the production of meat products. Sensory evaluation, microbiological examination and gluten detection were performed in samples of sausages, Poultry frankfurter, Fine salami and Malokarpatska salami. The meat products came from different producers and were purchased from a retail network. Sensory quality was determined by assessing color, aroma, juiciness, fragility and taste using a 5-point rating scale. The microbiological examination included the determination of the total number of microorganisms, the number of psychrotrophic, coliform microorganisms and coagulase-positive staphylococci. The presence of gluten alone was detected using a commercially produced GlutenTox Home test kit as well as a PCR reaction. Individual testing of selected meat products showed minor differences in the overall quality of gluten free and gluten-free meat products.
