The green seaweed : tomorrow's "wheat of the sea" in foods, feeds, nutrition, and biomaterials.

, a genus of green macroalgae commonly known as sea lettuce, has long been recognized for its nutritional benefits for food and feed. As the demand for sustainable food and feed sources continues to grow, so does the interest in alternative, plant-based protein sources. With its abundance along coastal waters and high protein content, spp. have emerged as promising candidates. While the use of in food and feed has its challenges, the utilization of in other industries, including in biomaterials, biostimulants, and biorefineries, has been growing. This review aims to provide a comprehensive overview of the current status, challenges and opportunities associated with using in food, feed, and beyond. Drawing on the expertise of leading researchers and industry professionals, it explores the latest knowledge on s nutritional value, processing methods, and potential benefits for human nutrition, aquaculture feeds, terrestrial feeds, biomaterials, biostimulants and biorefineries. In addition, it examines the economic feasibility of incorporating into aquafeed. Through its comprehensive and insightful analysis, including a critical review of the challenges and future research needs, this review will be a valuable resource for anyone interested in sustainable aquaculture and s role in food, feed, biomaterials, biostimulants and beyond.
