Macroalgae-based products are increasing in demand also in Europe. In the European Union, each category of macroalgae-based products is regulated separately. We discuss EU legislation, including the law on medicinal products, foods including food supplements and food additives, feed and feed additives, cosmetics, packaging materials, fertilizers and biostimulants, as well as biofuels. Product safety and consumer protection are the priorities with any new products. Macroalgae products can be sold as traditional herbal medicines. The novel food regulation applies to macroalgae foods that have not previously been used as food, and organic macroalgae are a specific regulatory category. The maximum levels of heavy metals may be a barrier for macroalgae foods, feeds, and fertilizers. Getting health claims approved for foods based on macroalgae is demanding. In addition to the rules on products, the macroalgae business is strongly impacted by the elements of the general regulatory environment such as agricultural/aquacultural subsidies, maritime spatial planning and aquaculture licensing, public procurement criteria, tax schemes, and trade agreements.

在欧洲，基于大型藻类的产品需求也在增加。在欧盟，每种基于大型藻类的产品均受到单独监管。我们讨论了欧盟立法，包括有关药品的法律，食品（包括食品补充剂和食品添加剂，饲料和饲料添加剂），化妆品，包装材料，肥料和生物刺激剂以及生物燃料的法律。产品安全和消费者保护是任何新产品的优先考虑。大型藻类产品可以作为传统草药出售。新的食品法规适用于以前从未用作食品的大型藻类食品，有机大型藻类是特定的法规类别。重金属的最高含量可能是大型藻类食品，饲料和化肥的障碍。要求对大型藻类食品的健康要求得到批准。除了产品规则外，大型藻类业务还受到一般监管环境要素的强烈影响，例如农业/水产养殖补贴，海洋空间规划和水产养殖许可，公共采购标准，税收计划和贸易协定。
