The European Food Safety Authority (EFSA) has established a temporary ADI of 75 mg per kilogram of bodyweight.<\/p>\n<p>In the United States, carrageenan and PES are permitted by the Food and Drug Administration (FDA) for use as a food additive when used in the amount necessary for the intended effect.<\/p>\n<h3>Market and growth<\/h3>\n<p>The global carrageenan market is expected to expand at a compound annual growth rate (CAGR) of 5.9% from 2020 to 2017, according to projections by Grand View Research.<sup>3<\/sup><\/p>\n<p>This demand is driven in part by the growing demand for thickeners and gelling agents from the food and beverage industries for products with natural ingredients. The ability of carrageenan to act as a fat replacer is also expected to increase its demand as consumers increasingly prefer low-calorie, convenient food products. Carrageenan also serves as an alternative to gelatin for vegan and vegetarian products.<\/p>\n<p>However, as consumers increasingly read nutrition facts labels and are more selective of products based on ingredients, carrageenan has stood out as an ingredient to avoid for many.<\/p>\n<p>These concerns are driven by research that has linked carrageenan to inflammation and cancer.<sup>4<\/sup><\/p>\n<p>While valid, these concerns are primarily based on a form called poligeenan, which, unfortunately, early studies did not distinguish between carrageenan and degraded carrageenan \u2013 or poligeenan.<sup>4<\/sup> Poligeenan is not approved for use as a food additive.<\/p>\n<p>Still, health concerns over carrageenan \u2013 while largely unfounded \u2013 may limit consumer acceptance and the market growth of carrageenan.<\/p>\n<h3>The bottom line<\/h3>\n<p>Extracted from red seaweeds, carrageenans are naturally occurring polysaccharides that provide gelation, viscosity, and structure to a variety of food applications.<\/p>\n<p>The three types of carrageenan \u2014 kappa, iota, and lambda \u2014 vary in sulfation, which affects their functional properties.<\/p>\n<p>The demand for natural thickener and gelling agents by the food and beverage industry is expected to drive the market growth of carrageenans to meet consumer preference for natural ingredients-based convenient food products. Still, misconceptions about the safety of carrageenan may limit consumer acceptance, forcing manufacturers to pivot and potentially reformulate.<\/p>\n<h3>References<\/h3>\n<ol>\n<li>Zia KM, Tabasum S, Nasif M, et al.
