Abstract
This study presents the DNA detection of the cytochrome b gene in thermally processed beef. The beef was subjected into different cooking temperatures: 50°C, 80°C, 100°C, and 121°C. The DNA of the sample for the different temperatures were isolated and analysed. In the first PCR procedure, the results were viewed using agarose gel electrophoresis and the full length of the cytochrome b gene was detected only up to 100°C. The second PCR procedure was done to detect only a fragment of the cytochrome b gene in thermally processed beef. The results showed that the small fragment of the cytochrome b gene can still be detected and amplified at very high temperatures (≥121°C). Thus, the full length of the cytochrome b gene can only be detected up to 100°C. To detect this gene at very high temperatures, smaller fragments should be isolated for analysis.
