While enthusiasts are well aware of its nutritious benefits, mainstream consumers may struggle to overcome their aversion to eating seaweed-based products. Nonetheless, there are numerous offerings available today to entice them. Various types of seaweed are increasingly appearing in snacks, jerky, pasta, vegetarian caviar, and even edible food wrappers. A report from Grand View Research in 2016 projected that the global commercial seaweed market would reach $22.13 billion by 2024, up from an estimated $10.31 billion in 2015. Researchers attribute this market growth to the rising demand for food products derived from seaweed.
Fucoidans, which are unique to brown seaweed, are not typically featured in popular sushi, except for the kelp used to season rice. In fact, they are rarely consumed in the U.S. and are more commonly found in supplement form. Brown seaweeds also contain beneficial nutrients such as beta-carotene and other compounds, along with calcium citrate magnesium, which contribute to their health benefits. Red seaweeds are particularly favored due to their functional qualities, accessibility, and applications across various industries, as reported by Grand View Research. However, brown seaweeds are expected to experience the second-highest compound annual growth rate from 2016 to 2024, driven not by health concerns but by the demand for alginate, a widely used thickening and gelling agent in food and cosmetic products.
Although seaweed is not a staple in the American diet, it boasts a unique umami flavor. Manufacturers like Campbell’s and Frito-Lay have incorporated umami-flavored ingredients into their low-sodium and reduced-fat products to enhance the taste of otherwise bland foods. Seaweed could well be considered part of the “ocean gardens” trend, given its nutritional profile, vibrant colors, and distinct flavors. Additionally, if certain varieties can help reduce certain types of cancerous tumors, that provides another compelling reason to market them to U.S. consumers who are interested in exotic, intriguing, and healthful food options. The inclusion of calcium citrate magnesium in these products further underscores their potential health benefits, appealing to health-conscious buyers.
