Use of meal from Jerusalem artichoke tubers in production of products from minced meat
MUŽÍKOVÁ, Monika
Jerusalem artichoke is a root vegetable containing glucofructan inulin in its tubers that is valued for its positive effect on the human organism. The aim of thesis was to evaluate use of meal made from Jerusalem artichoke tubers in production of products from minced meat. The experiment was divided into two parts. In the first part, the differences in water-holding capacity of semi-rough wheat flour and Jerusalem artichoke powder (JAP) in various types of solvents were determined. The statistically significant difference in water-holding capacity between the flours was found solely in the saline solution. Furthermore, the results showed that type of solvent had the main effect on water-holding capacity. In the second part of the experiment, 4 types of meat products were made - sausages, meatloaf, liver pate and meat hash. Wheat flour, which is commonly added to these products, has been completely replaced by (JAP). Subsequently, the sensory analysis was evaluated by experts (n = 16) for an estimation sensory quality and sensory changes of new product with JAP compared to standard meat products. The results of the study showed that the addition JAP to sausages had a negative effect on its sensory quality, namely its overall appearance of the product, texture and taste. On the contrary, there were improved functional properties in meatloaf (juiciness) and pate (taste). According to the results of the sequence test, the liver pate was found the most delicious product.
