FoodEx2 maintenance 2021

FoodEx2 is a comprehensive food classification and description system developed and maintained by EFSA to cover the needs of data collections in different domains. To ensure its full applicability, the system needs to be kept up to date and therefore, a regular maintenance of the system is needed. Four major updates were carried out so far and all performed changes are described in the annual maintenance reports. This technical report describes the outcome of the fifth maintenance process done in 2021 which contained addition of new terms, reportability changes of some terms and amendments to existing terms including enrichment of implicit facets and changes of the parent‐child relationship.
