Calcium Alginate Price Trend 2024
In 2024, calcium alginate prices experienced significant volatility, primarily driven by complex global market dynamics affecting seaweed production. South Korea, commanding over 70% of the global dried seaweed market, faced unprecedented challenges with seaweed harvests impacted by rising ocean temperatures and marine desertification.
The pricing was substantially influenced by multiple interconnected factors. Japan's seaweed harvests reached near-record lows, with wakame production in the Sanriku coastal region hitting historic minimums since 1977. This scarcity was compounded by a global surge in demand, particularly from markets like the United States, where Korean seaweed products were increasingly popular.
Structural industry challenges further complicated the pricing landscape. Over 40% of fishing village populations were aged over 70, indicating significant demographic stress in seaweed farming. The Ministry of Oceans and Fisheries in South Korea responded by planning to expand seaweed farming areas by approximately 2,700 hectares and researching high-temperature-resistant seaweed variants.

Calcium Alginate prices kept on vacillating in accordance with the fluctuations in the prices of its feedstock material seaweed, but the overall market outlook was still very firm throughout. Tanzania, the biggest seaweed producer, registered a record 52% year-on-year growth in the seaweed yield in the third quarter. This essentially reduced the production costs of calcium alginate and reduced the upstream cost support, imparting a slide in the calcium alginate price trend.
The downstream demands from the food and medicine industries also remained steady, and the inventories were also stocked sufficiently. All these factors dictated an average performance of the calcium alginate market throughout the second half of the year 2023.
About Calcium Alginate
Alginate is usually referred to as the salts of alginic acid and can exist as calcium, magnesium, and sodium salts and is often referred to as algin. Calcium alginate is a water-insoluble, gelatinous substance prepared by adding aqueous calcium chloride to sodium alginate. It is non-toxic and is generally recognized as safe in food. It is often used as hydrogels, dental impressions materials, absorbents, etc.

Calcium Alginate Production Processes
- Production of Calcium Alginate from Extraction Process
The seaweed is broken into pieces to extract the alginate and stirred with a hot sodium carbonate solution. It then separates as a thick slurry of sodium alginate. The slurry is then diluted with water and subjected to many filtration processes to remove the impurities. Then the sodium alginate is treated with an aqueous solution of calcium chloride; thus, the required product calcium alginate separates from the solution.
