Seaweed, an underwater superfood abundant in complete proteins, vitamin B12, and omega-3 fatty acids, could soon transform the way we fulfill our nutritional needs and secure a sustainable future for our food sources. Researchers at Sweden’s Chalmers University of Technology have discovered a groundbreaking method to more efficiently extract proteins from seaweed, offering a sustainable alternative to traditional protein sources.
Breaking down the protein barrier
While seaweed naturally contains complete proteins and essential nutrients, accessing them has been challenging. Proteins in seaweed are often tightly bound to the plant’s cellular structure, with some soluble in water and others in fats. Until now, extracting the latter has been particularly difficult.
Led by João P. Trigo, the research team developed a two-step process that triples the protein yield from Ulva fenestrata, a type of sea lettuce. This method brings us closer to making seaweed protein extraction as accessible as it is today for soy and corn proteins, Study Finds reports.
Sustainable seaweed: A rich source of nutrients
Sea lettuce boasts not only a high protein content but also vitamin B12 and omega-3 fatty acids, making it an attractive option for plant-based diets. Unlike land-based crops, seaweed requires no irrigation, fertilizers, or pesticides, and its cultivation can benefit marine ecosystems by reducing ocean acidification and creating habitats for marine life.
The extracted protein contains all essential amino acids, with higher levels of lysine than previously achieved. Moreover, the process allows for the co-extraction of omega-3 and omega-6 fatty acids, enhancing the nutritional value of the final product – a dark green powder suitable for various foods.
Innovative extraction techniques
The new method begins by using Triton X-114 surfactant to open the cellular membranes of seaweed. An alkaline solution then extracts the proteins, followed by an acidification step that separates them from the water. Although currently intended for laboratory use, researchers are actively working on safer alternatives for consumption.
This process aligns with broader sustainability efforts, as Chalmers scientists collaborate with Gothenburg University to cultivate sea lettuce with elevated protein content. By using processed water from the seafood industry, they recycling valuable nutrients and reducing waste.
Meeting global protein demand
As the global population grows, traditional protein sources face increased pressure. Seaweed agriculture offers a scalable solution that combines superior nutritional value with minimal environmental impact. Ingrid Undeland, coordinator of the CirkAlg project, emphasizes the importance of diversifying protein sources.
"Humans will need to combine the consumption of diverse protein sources to meet sustainability and nutritional goals. Seaweed complements many existing products on the market," Undeland asserts.
Ultimately, the goal of this research is to utilize all parts of seaweed for food, materials, or medical applications, ensuring no molecules go to waste and establishing a sustainable and commercially viable ‘blue-green’ industry.
