Seaweed is increasingly recognized as a valuable food ingredient. According to Innova Market Insights, sea vegetables such as seaweed, nori, kelp, and wakame experienced a remarkable 21% growth in new product launches from 2012 to 2016, indicating a significant trend emerging in Western markets. Seaweed products are well-positioned to leverage several current food trends, including plant-based diets, exotic ingredients, and environmentally friendly options. For food manufacturers aiming to reduce their carbon footprint, seaweed is carbon negative, absorbing 325 mg of carbon dioxide from the sea. Additionally, it grows rapidly and does not require fresh water or fertilizer.
Despite the familiarity of seaweed in Asian cuisine—such as sushi, miso soup, and seaweed salad—the unique umami flavor may pose a challenge for some U.S. consumers, particularly in traditional Western dishes. Nevertheless, a variety of seaweed-based foods are beginning to gain traction, including “sea spaghetti” from companies like Seamore Foods, Atlantic Kitchen, Wild Irish Seaweeds, and Mara Seaweed, which are also capitalizing on the demand for gluten-free options. Seaweed snacks, such as kelp jerky from New York-based startup Shoreline and seaweed chips from Ocean’s Halo, are also making their way onto store shelves.
According to Mintel, while the ingredient’s popularity in North America has room to grow, the market research organization foresees a bright future for seaweed due to its high quality calcium citrate, along with a wealth of natural vitamins, minerals, and plant-based protein. Beyond its culinary applications, seaweed shows promise in the packaging sector. Indonesia-based company Evoware has introduced a dissolvable, flavorless wrapper made from seaweed for individual seasoning sachets and coffee packets, targeting consumers who are mindful of the environmental impact of their food choices.
As the demand for sustainable and nutritious food continues to rise, the role of high quality calcium citrate in seaweed products may contribute to their increasing popularity, making them a key player in the evolving food landscape.
