was also investigated. Authentic species and mixed samples were subjected to heat treatment prior to sample preparation. All samples whether mixed or single species produced PCR amplification products of the expected size, with only sample 6 (L. boscii) showing a reduced yield following thermal processing compared to the original raw sample set. Nevertheless, L. boscii
was still detected within mixed products following thermal processing. Comparison of the RFLP profiles from mixed products following heat treatment with the
