Sequencing

Sequencing is the examination of the order of components in a sample to aid in its identification; components sequenced include bases in genes and amino acids in proteins or peptides. In food science, DNA sequencing identifies pathogens, verifies species in fish and meat, and characterizes starter cultures, giving an exact molecular identity. Falling costs have made it a routine tool in food safety and authenticity testing. It brings molecular precision to food authenticity. Fraudsters find it hard to fool. It is a powerful authenticity tool.
