The diploma thesis deals with micromethod of DNA isolation from ten differently processing food products containing pepper (Capsicum annum). PCR ready DNA was isolated by magnetic particles PGMA functionalized by carboxyl groups from homogenates prepared in lysis buffer with CTAB. Quantity and quality of DNA was estimated using spectrophotometric measurements and verified using PCR methods with primers specific for plant rDNA. Quality of isolated DNA varied depending on processing technology. DNA isolated from smoked grinded peppers and from heat treated food products was degraded and amplified with primers F_26S and R_26S (PCR product 220 bp) in contrary to the primers F_18S and R_5.8S (PCR product 700 bp). DNA isolated from the other food products was amplified with primers F_18S and R_5.8S (PCR product 700 bp). PCR product from one grinded pepper (Žitavská paprika) was cloned and sequenced.
