How Europe is Emerging as a Growth Hub in the Seaweed Protein Industry

According to a research report, “Seaweed Protein Market by Source (Red Seaweed, Green Seaweed & Brown Seaweed), Extraction Process (Conventional Method & Current Method), Mode of Application (Food, Animal Feed & Additives, Personal Care & Cosmetics) & Region - Global Forecast to 2027” published by MarketsandMarkets, the seaweed protein market was valued at USD 585 million in 2022 and is projected to grow at a CAGR of 14.1%, reaching USD 1,131 million by 2027.

The rising health awareness among consumers is a key driver of this growth. Seaweed proteins are emerging as a popular application within the broader plant-based products segment, with the food and nutrition industries increasingly focusing on personalized supplementation to address dietary deficiencies.

Green Seaweed Leading Growth

Among the types of seaweed, green seaweed is projected to achieve the highest CAGR in the market. Known scientifically as chlorophyte, green seaweeds get their color from beta-carotene, chlorophyll, and xanthophylls. They exist in both multicellular and unicellular forms and are primarily found in freshwater environments, though they can also grow in marine habitats or on terrestrial surfaces like soil, trees, or rocks.

Green seaweeds have long been a staple in Japanese cuisine and are valued for their rich mineral content, including calcium, copper, iodine, iron, magnesium, manganese, molybdenum, phosphorus, potassium, selenium, vanadium, and zinc. Popular edible types include sea lettuce, sea palm, and sea grapes. Beta-carotene extracted from green algae is used as a food coloring and has been linked to cancer prevention benefits. Protein content in green seaweeds ranges from 9–26% of dry weight, making them a viable source for food manufacturing.

Conventional Extraction Methods Dominate

By extraction method, the conventional method holds the largest seaweed protein market share. This method involves physical processes such as aqueous treatment, Potter homogenization, osmotic stress, and high shear force to extract proteins from species like Palmaria palmata, Ulva fasciata, Sargassum vulgare, and Porphyra. Among these, enzymatic hydrolysis has emerged as the dominant process. Conventional extraction is favored due to its minimal processing, which appeals to consumers seeking natural ingredients.

Food Applications Drive Market Demand

The food segment is the largest mode of application for seaweed protein. The shift toward natural food additives, which are safer than synthetic components, is fueling demand. Seaweed protein-based products are widely used in human food applications, including vitamins, semi-sweet biscuits, cereal bars, breadsticks, and even in enhancing the nutritional profile of wheat and pasta. Their natural antioxidants, anti-inflammatory agents, and plant proteins make them highly desirable for health-conscious consumers. This rising adoption is boosting the overall seaweed protein market size.

Europe Emerges as a Growth Hub

Europe is expected to register the highest CAGR in the seaweed protein industry. Initiatives like EU4Algae, supported by the European Commission and partner organizations, aim to boost sustainable algae production and introduce new algae species to the market. The European Commission has recognized seaweed protein as a key alternative protein source, contributing to global food security and a climate-friendly food system.
