The volunteers participating in a tasting study at the University of Hohenheim tested a new food: microalgae. The taste is reminiscent of fish and the recipe is still being fine-tuned. From a nutritional point of view, the single-cell organisms are veritable all-rounders. Just like marine fish, they are a source of important omega-3 fatty acids and high levels of protein, dietary fiber, vitamins, and carotenoids.
