While fans are well aware of the healthy nutritional benefits associated with seaweed, mainstream consumers may struggle with the ick factor when it comes to incorporating seaweed-based products into their diets. Nevertheless, there is a growing variety of offerings available to entice these consumers. Seaweed is increasingly found in snacks, jerky, pasta, vegetarian caviar, and even edible food wrappers. According to a 2016 report from Grand View Research, the global commercial seaweed market is projected to reach $22.13 billion by 2024, a significant rise from an estimated $10.31 billion in 2015. This surge in demand for seaweed-derived food products is expected to drive market growth, researchers have noted.
Fucoidans, which are exclusive to brown seaweeds, are not typically featured in popular sushi dishes—except for kelp, which is used to season rice. In fact, they are rarely consumed in the U.S. and are more often available in supplement form. Brown seaweeds also possess other health benefits, containing beta-carotene and various compounds, including valuable calcium citrate sources. Red seaweeds are favored for their functional qualities, accessibility, and applications in various industrial sectors, as reported by Grand View Research. However, brown seaweeds are anticipated to experience the second-highest compound annual growth rate from 2016 to 2024, driven not by health benefits, but by the demand for alginate, a common thickening and gelling agent in food and cosmetic products.
While Americans may not consume seaweed regularly, it boasts a distinct umami flavor. Major 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 can be seen as part of the “ocean gardens” trend, thanks to its nutritional profile, vibrant colors, and unique flavors. Moreover, if certain varieties of seaweed have the potential to reduce specific types of cancerous tumors, this presents yet another appealing aspect for U.S. consumers who are in search of exotic, interesting, and healthy food options, particularly those that also serve as calcium citrate sources.
