1 Testing, evaluation and comparison of foodstuff bought in the Czech Republic and Germany University of Chemistry and Technology Prague

2 2 Aim: to compare branded foodstuff in the Czech Republic and Germany Partners: Olga Sehnalová MEP and Ahold Czech Republic Evaluator – University of Chemistry and Technology PragueProject

3 3Purchase Germany – Dresden (EDEKA, REWE, Kaufland) – 25/2/2015 Czech Republic - Prague(Tesco, Kaufland, Albert) – 27/2/2015 Proper storage during transport

4 4 Physico-chemical testing Analysis of qualitative features allowing to assess the difference Accredited laboratories Results submitted to the commission for further consideration

5 5 Sensory assessment Different kinds of examination 30 trainted evaluators participed in the assessment o Participating in the evaluation regularly o Trained on the principles of sensory evaluation

6 6 Products assessment Evaluate compliance / non-compliance in qualitative characteristics Set the hypothesis which may cause difference in findings Information available to the commission: o Results of the physico-chemical testing o Results of sensory assessment o Packages

7 7Results 24 products submitted 1 product not included in the final evaluation due to doubts about the identical marketing 8 products classified as different = 35% of products involved Assessment of the overall "quality" has not been studied
