| Description
| - High quality and purity of DNA isolated from food and feed is essential for species identification and has unpredictable influences an effect of analysis. In this study, the efficiency of eight different methods for DNA isolation was investigated. For DNA extraction, the raw chicken meet, ham, sausages, tinned lunch meat, pate, tinned feeds for dogs, complete granulated feeds for dogs and chicken flour were used. Kits of several different producers, i.e.: NucleoSpin Food (Marchery-Nagel), Wizard Genomic DNA Purification Kit (Promega), Invisorb Spin Food Kit I (Invitek), Wizard SV Genomic DNA Purification System (Promega), JetQuick Tissue DNA Spin Kit (Genomed), RNA Blue (Top-Bio), JetQuick Blood & Cell Culture Kit (Genomed), QIAamp DNA Mini Kit and QIAamp DNA Blood Mini Kit (Qiagen) were employed in the study. Gel agarose electrophoresis for primary verification of DNA quality was performed. The isolates were subsequently assessed for quantity and quality using by spectrophotometer Nanodrop 2000 (Thermo Scientific). To verify of template usability and quality of isolated DNA, the polymerase chain reaction (PCR) was used. The best results were obtained with NucleoSpin Food and JetQuick Tissue DNA Spin Kit. DNA extracted by these methods proved highest yields, purity and template quality in all foods and feeds and the results of PCR analysis are excellent reproducible. Analyses showed that results depended on different food or feed using and different isolation system. The results of this work will be utilized to choose the suitable isolating kit for educational course, which is designed for students and also for following research and analyses.
