“Novel Food is defined as food that has not been consumed to a significant degree by humans in the EU prior to 1997, when the first Regulation on novel food came into force.
Novel Food can be newly developed, innovative food or food produced using new technologies and production processes as well as food traditionally eaten outside of the EU.
Novel Food must be:
Safe for consumers;
Properly labelled to not mislead consumers” (Source: European Commison site).
Edible insects are a Novel Food. You can find the others in the Official Catalogue.
