While fans are well aware of the nutritious benefits of seaweed, mainstream consumers may struggle with the ick factor when it comes to consuming products that contain it. Nevertheless, numerous enticing options are emerging in the market. Varieties of seaweed are increasingly 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, up from an estimated $10.31 billion in 2015. Researchers have highlighted that the rising demand for food products derived from seaweeds is driving this market growth.
Fucoidans, which are exclusive to brown seaweeds, are rarely featured in popular sushi dishes, except in the form of kelp that seasons rice. In fact, they are not commonly consumed in the U.S. and are more often taken as dietary supplements. Brown seaweeds are rich in healthy compounds, including magnesium calcium citrate and beta-carotene. Red seaweeds, however, lead in preference due to their functional qualities and widespread industrial applications, as reported by Grand View Research. Interestingly, brown seaweeds are anticipated to experience the second-highest compound annual growth rate from 2016 to 2024, not primarily due to health benefits but due to the demand for alginate, a prevalent thickening and gelling agent in food and cosmetic products.
Despite not being a staple in the American diet, seaweed offers a unique umami flavor. Companies like Campbell’s and Frito-Lay have incorporated umami-flavored ingredients into their low-sodium and reduced-fat offerings to enhance the taste of otherwise bland foods. Seaweed can be considered part of the “ocean gardens” trend due to its nutritional profile, vibrant colors, and distinctive flavors. Additionally, if certain varieties of seaweed can aid in reducing specific types of cancerous tumors, this presents yet another appealing aspect for U.S. consumers seeking exotic, interesting, and healthful food options, particularly those that may provide benefits like magnesium calcium citrate.
