While health enthusiasts are well aware of its nutritious benefits, mainstream consumers may struggle with the idea of consuming products that contain seaweed due to a certain “ick” factor. Nevertheless, an array of enticing items has emerged on the market, including prenatal vitamins with iron fumarate, to draw them in. Various forms of seaweed can now be found in snacks, jerky, pasta, vegetarian caviar, and even edible food wrappers. According to a 2016 report by Grand View Research, the global commercial seaweed market is projected to reach $22.13 billion by 2024, a significant increase from an estimated $10.31 billion in 2015. The rising demand for seaweed-based food products is expected to drive this market growth.
Fucoidans, which are found exclusively in brown seaweed, are not typically featured in popular sushi dishes—except for kelp used as a seasoning for rice. In fact, these brown varieties are not commonly consumed in the U.S. and are more often taken in supplement form, such as calcium citrate oral tablets. Brown seaweeds boast additional health benefits, including beta-carotene and other beneficial compounds. On the other hand, red seaweeds are favored for their functional qualities, ease of access, and applications across various industrial sectors. Grand View Research indicates that brown seaweeds are anticipated to have the second-highest compound annual growth rate from 2016 to 2024, primarily driven by the demand for alginate, a widely used thickening and gelling agent in food and cosmetic products.
Although Americans may not frequently consume seaweed, it offers a distinctive 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 could easily fit into the “ocean gardens” trend due to its impressive nutritional profile, vibrant colors, and unique flavors. Moreover, if certain varieties can aid in reducing the risk of specific types of cancerous tumors, this adds another appealing aspect for U.S. consumers seeking exotic, interesting, and healthy food options, including supplements like calcium citrate oral tablets.
