What are Commercial Seaweeds?
Commercial seaweeds are marine algae. They are cultivated and harvested for diverse applications. They are used across food, agriculture, pharmaceuticals, cosmetics, biofuels, and industrial sectors. These seaweeds are valued for their high nutritional content, bioactive compounds, and environmental sustainability benefits. Rising demand for plant-based products, functional ingredients, and biotechnology innovations boosts the adoption of commercial seaweeds.
The expansion can be credited to factors such as the elevated nutritional value and health advantages, a heightened embrace of seaweed for hydrocolloids, and a growing demand for seaweed in diverse end-use sectors, including personal care, pharmaceuticals, agriculture, food and beverages, and animal feed.
Farmers incorporate seaweed extract in agriculture as it proves to be an excellent fertilizer for crop production, demonstrating novel mechanisms that enhance crop productivity. The awareness of seaweed's utility in crop production has led to farmers observing additional benefits, such as improved root structures of plants. Additionally, seaweeds contribute to enhancing soil microbiology, soil structure, and water retention capacity, anticipating increased product demand in the forecast period.
Seaweed, being a rich source of iodine, a nutrient scarce in other foods, plays a crucial role in regulating estradiol and estrogen levels in the human body. The utilization of seaweed and its isolates is known to boost satiety, reducing postprandial glucose and lipid absorption rates, thereby contributing to the development of anti-obesity foods. Furthermore, the anti-microbial properties of seaweeds position them as ingredients or consumed foods, offering preservative benefits to various food products.
Increasing environmental awareness has brought about notable shifts in consumer preferences, driving the desire for sustainable products. Cultivation of macroalgae is regarded as a sustainable practice, given the fast growth and nutrient-rich properties of algae, which contribute to oxygen emission and carbon dioxide absorption. The growing popularity of plant-based products and the adoption of veganism further fuel the demand for seaweed production. As per the State of the Industry Report 2021 by the Good Food Institute, sales of plant-based meat witnessed an almost 50% growth from 2019 to 2021. Consequently, the escalating demand for plant-based products is anticipated to propel Commercial Seaweed market growth.

Increasing Utilization of Seaweeds in Food Processing, contributing to market growth.
Seaweeds find widespread use in diverse global cuisines. While traditionally consumed in China, Japan, and South Korea, the demand for seaweed as a food source has expanded with the migration of consumers from these regions to other parts of the world. This is evident in the increasing demand in certain areas of the United States and South America, where the Asian population is growing. Notably, efforts by French government and commercial entities have successfully promoted seaweeds for culinary purposes in restaurants and households. Additionally, in some developing nations with a tradition of using fresh seaweeds in salads and as vegetables, an informal market has emerged among coastal residents.
Numerous studies have assessed the gelling, thickening, and therapeutic properties of seaweed when utilized independently. This research also underscores the nutritional, textural, sensory, and health-related attributes of food products enhanced with seaweed and its extracts. The impact of incorporating seaweed into various food items such as meat, fish, and bakery products has experienced significant growth within the food and beverage industry. Recent data from the United Nations Commodity Trade reveals a consistent increase in the export/import value of seaweed (2012-2020) and other forms of algae intended for human consumption in Europe. This trend signals a notable uptick in the utilization of seaweed ingredients within the food processing industry, both in Europe and the global market.
