2DLC in Food Safety and Traceability

Article

With so many potential routes for food contaminants, both natural and otherwise, having the tools to detect them, determine the source of the problem and prevent them from reaching the consumer is therefore vitally important. In this article, we explore how 2DLC is being implemented to improve food safety and contaminant traceability.

Exploring an Enigmatic Sea Monster’s Genome
News

In 1857, the Danish naturalist Japetus Steenstrup linked the tell tales of ships being dragged to the ocean floor to the existence of the giant squid: A ten-armed invertebrate, that is credibly believed to grow up to 13 meters and weigh over 900 kg. Now, more than 160 years later, an international team of scientists have sequenced and annotated the genome of a giant squid.

Why We Should Consider Our Food Packaging and Not Just Our Food
Article

Whilst we can detect some contaminants by their taste or aroma, not all contaminants can be detected by our senses. Mineral oil-based chemicals are one such group and are attracting increasing interest from food analysts as we found out when we spoke to Professor Erich Leitner, a leading expert on food quality at the Graz University of Technology in Austria.
