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 Malokarpatská 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.

Highlights
Cereals are an essential and very important part of our diet
3.1 Results of sensory evaluation of meat products Based on an overall evaluation of the results of sensory evaluation of meat products, the sample of “Malokarpatská salami“ not declared as gluten-free obtained the largest number of points in the summary as well as in all evaluated features, namely 21.3 points out of a possible 25 points
The lowest number of points in the sensory evaluation was obtained by all samples of Poultry Sausages and Fine Salami
Summary
Cereals are an essential and very important part of our diet. After consumption and processing in the gastrointentinal tract, they provide the body primarily with energy in the form of carbohydrates, minerals, vitamins and are a source of fiber. Rice and corn are the most consumed in the world. Consumption of cereals is often associated with various diseases. Those we can divide into autoimmune, non-autoimmune, allergic and non-allergic. Celiac Disease is one of the most famous autoimmune disease. The Triticeae (wheat, barley, rye) and Aveneae (oats) cereal families cause health problems for patients suffering from celiac disease and cereal allergies (Abaffyová et al, 2015)
