Growth Factors in the Seaweed Industry:

• Rising Demand in the Food and Beverage Industry

Seaweeds are popular due to growing health consciousness, demand for food products with high nutritional value and natural origin. Seaweeds serve in ready-to-eat meals, seasonings, snacks and sauces for umami flavor, thickening properties, versatility, natural origin and clean label. Hence, seaweeds are widely used in food processing as a food ingredient within. Seaweed compounds react to synthetic additives in food more and more when used in alternative products for dairy and meat like natural stabilizers, hydrocolloids, and salt-reducers. They improve the products' texture, moisture retention, and nutritional properties throughout production. Global food chains develop seaweed crisps noodles and nutraceuticals. Cultivated seaweed grows rapidly, ensuring a stable supply for manufacturers who benefit from a predictable supply and innovate using this new material. Through the rise of the clean-eating phenomenon, seaweed has become a contemporary go-to food ingredient of choice for many.

• Growing Awareness about Health Benefits

Health-conscious consumers increasingly embrace seaweed. It is a superfood that has vitamins, minerals, antioxidants, amino acids, and omega fatty acids. Demand regarding the consumption of seaweed in mainstream diets is also rising in response to perceived health benefits associated with immune system, metabolism, and digestive support. Research finds seaweed bioactive compounds interesting due to anti-inflammatory, cholesterol-lowering and detoxifying activities including fucoxanthin, alginates and polyphenols. Scientific and clinical evidence regarding the health benefits of seaweeds has encouraged the use of functional foods and dietary supplements improved with seaweed. Seaweed capsules, powders, gummies and fortified food products are being developed and marketed by global wellness brands for growing demand. Because of a rise in lifestyle diseases in developed and developing countries, preventive nutrition-based wellness seaweed products are rising in popularity.

• Expanding Applications in Pharmaceuticals and Cosmetics

Bioactive compounds exist in seaweed so seaweed extracts become an increasingly common ingredient in pharmaceuticals and cosmetics. The bioactive compounds provide anti-aging, moisturizing, skin lightening, and skin barrier repairing properties for skin. Seaweed extracts are therefore an ingredient in cosmetics that include serums, creams, masks, and dermatological products. Pharmaceutical companies have explored bioactive compounds from seaweeds for liver protectants, metabolic stimulants, antibiotics and antimicrobial agents, and anti-inflammatories. As the use of nutraceuticals has increased, seaweed extracts are more commonly sold in capsule or tonic form or as part of functional health products. Red, brown or green seaweeds are increasingly used in natural or sustainable branded cosmetics. The clean beauty trend is rising so products with plants or sea sourced ingredients that have scientifically proven benefits are becoming more popular for people who want plant- and sea-sourced ingredients.

Key Trends in the Seaweed Market

• Shift Toward Sustainable Seaweed Cultivation and Climate Solutions

Seaweed appears to be a good choice for sustainable agriculture systems and climate-positive supply chains because seaweed farms currently need no freshwater for irrigation, no fertilizer, and no arable land. Regenerative ocean farms result from their driving. Governments and climate-focused organizations back seaweed in carbon sequestration, shoreline protection, and biodiversity restoration. Other potential products exist from seaweed biomass such as biodegradable packaging, bioplastics, organic fertilizer, and low-methane animal feed. Companies invest in traceable, certified and low-impact seaweed. This helps companies comply with stricter climate policies. Companies also avoid the risk of overharvesting from overexploited areas in their supply chains. The trend is pushing the market forward and attracting new investors to seaweed production.

• Advancement in Seaweed Processing Technologies

New processing methods have improved the production of high-purity ingredients from seaweed for use in food, cosmetics, pharmaceuticals and other industrial products. Enzymatic hydrolysis, cold processing, and membrane filtration are increasingly used to improve product quality. Tools for quality assessment of AI and machines for drying support consistent product processing in mass quantities in world supply chains. Equipment to separate compounds including fucoidan, carrageenan and ulvan is important for the increase of high-value products in the nutraceutical and cosmetic industries. These improvements promise that production costs will lower, applications will have more potential, and seaweed-derived products will commercialize more globally.

• Growing Commercial Expansion of Red and Specialty Seaweed Products

As commercial applications continue to increase for food structuring, gelling and pharmaceutical products, the cultivation of red seaweed to produce carrageenan, agar and specialty extracts for markets such as dairy alternatives, plant-based meats and confectionery is expected to grow. Agricultural scientists have also begun to focus on the use of red seaweed as a bio-stimulant crop to improve plant growth, soil improvement and pest resistance. Specialty seaweed varieties are also being used as gourmet foods, ingredients in cosmetics, and flavoring agents in functional beverages. Red seaweed and specialty varieties such as carrageenans are some of the fastest growing products in this category, as demand for natural high-performance materials increases.
