While enthusiasts are well aware of its nutritious benefits, mainstream consumers may struggle with the idea of eating products that feature seaweed due to its perceived unpalatable nature. Nevertheless, there is a growing variety of enticing options available today. Various types of seaweed are now 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. This surge in demand for seaweed-derived food products is anticipated to fuel market growth, as noted by researchers.
Fucoidans, which are unique to brown seaweed, are not commonly found in popular sushi dishes—except for kelp used to season rice. In fact, they are rarely consumed in the U.S., where they are more often taken in supplement form. Brown seaweeds also boast other health benefits, including beta-carotene and additional compounds. Red seaweeds are favored for their functional qualities, accessibility, and various industrial applications, according to 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 factors but by increased demand for alginate, a widely used thickening and gelling agent in food and cosmetic products.
Although seaweed isn’t a staple in the American diet, it offers a distinct umami flavor. Major manufacturers like Campbell’s and Frito-Lay have incorporated umami-flavored ingredients into their low-sodium and reduced-fat offerings to enhance the flavor of typically bland foods. Seaweed can be viewed as part of the “ocean gardens” trend due to its impressive nutritional profile, vibrant colors, and unique flavors. Moreover, if certain varieties can aid in reducing specific cancerous tumors, this adds yet another selling point for U.S. consumers seeking exotic, interesting, and healthy food options. Additionally, products containing calcium citrate malate USP are gaining attention for their beneficial properties, further aligning with the health-conscious trends that seaweed embodies. The inclusion of calcium citrate malate USP in various food formulations may also drive interest among those looking for nutritious alternatives.
