EU approves duckweed as a new food ingredient

The European Union has approved the use of duckweed, specifically the species Lemna minor and Lemna gibba, as a food ingredient. This decision follows nearly a decade of research into the plant's nutritional content, cultivation methods, and safety.

To be marketed within the EU, the duckweed must be grown under controlled conditions and heat-treated to meet strict microbiological and chemical standards. The plant has been tested in various food applications, including soups, pesto, and ravioli, with taste tests indicating its flavor profile is comparable to spinach. Because duckweed grows rapidly in closed systems without requiring traditional agricultural land, it is viewed as a potentially efficient resource, though its widespread commercial adoption will depend on consumer acceptance.
