Detection of the Species Composition of Food Using Mitochondrial DNA: Challenges and Possibilities of a Modern Laboratory
Monitoring food quality is an important and constant element of the food market. This need is connected with health issues, religious beliefs of consumers, and economic considerations. For analysis, mtDNA is most commonly used because it is resist to physical factors such as temperature and pressure, which very often accompany food processing. Nowadays, scientific publications present a number of methods describing species identification from both farm animals and also less common animals. The most effective methods for determining species are based on PCR, real-time PCR, and sequencing. The methods are very sensitive, limit of detection (LOD) is 0.001% for many of them. An indispensable element of performing the described research is the strict application in the laboratory of several principles, which are intended to improve the work and make it safe for the lab technician, as well as guarantee the quality and effectiveness of the experiments carried out. The high work requirements set for the crew naturally shape the quality system from which the most popular is ISO/IEC 17025. Modern methods based on mtDNA are a good tool for food analysis, creating great opportunities for the researcher, at the same time causing challenges for the contemporary laboratory.
