Alginate Market Size

The global alginate market size was valued at USD 890.73 million in 2024 and is expected to reach USD 935.35 million in 2025 to USD 1382.99 million in 2033, growing at a CAGR of 5.01% over the forecast period (2025-2033). 

Alginate is a polysaccharide obtained from brown algae that occurs naturally. Sodium, calcium, and potassium alginate, which can entangle with water to produce a viscous gum, are available commercially in flagellated and granular forms. Consequently, alginate is extensively used to stiffen food products like jellies, jams, ice creams, marmalades, frozen desserts, chocolates, and instant noodles. Textile, paper, and pulp handling are among its many applications. Alginate has more excellent biocompatibility and cost-effectiveness and lower toxicity than other commonly used thickening substances.

The global market is anticipated to witness significant growth in light of increasing demand for the product in the manufacture of food products such as ice-cream yogurt and bakery products. Additionally, the use of alginates in the food & beverage industry is permitted by major regulatory agencies, including FDA and the European Commission, which drives its demand.

Alginate Market Growth Factors

Growing alginate penetration in the food industry

Alginate is used predominantly in the food industry as an emulsifier, a thickening agent, and a gelling agent. The high demand for alginate in the food industry is primarily due to its increased acceptance, driven by naturally existing raw materials for its production. The product finds application in the production of sauces, bakery products, and confectionery items. In light of increased domestic consumption, the food and beverage industry growth in BRICS and the Middle East is anticipated to act as a critical driver for the transition.

On account of rising consumer awareness regarding products with exotic and traditional tastes, the increasing need for convenience foods is expected further to promote the market growth in the coming years. The rising number of bakeries in Europe, on account of changing consumer eating habits, is expected to drive the demand for emulsifiers such as alginate, which are considered fit for human consumption. The increasing number of product-specific bakeries is also projected to result in emulsifying companies producing substances that provide optimum results to the final product.

Lack of time and rising consumer purchasing power have fueled demand for packaged goods, which is likely to continue during the projection period. For example, McCain, ConAgra, and Unilever have strengthened their global reach by making their products widely available in local retail stores and hypermarkets. Combined, these factors are projected to drive packaged food demand, positively impacting the market in the following years. and for packaged food in the coming years, thereby affecting the market positively

Restraining Factors

Volatile production of seaweed

The harvesting of seaweed has significant environmental and economic impacts on account of unsustainable production techniques. Seaweed harvests, primarily from wild stocks, are affected by climatic changes and overexploitation. For example, in Northern Ireland, one of the significant harvesters of seaweed, unsustainable harvesting techniques in areas of conservation importance were found to disturb the wildlife. This led to an increased demand for sustained harvesting techniques, thus leading to a decline in the volume of seaweed produced. The market in China is also likely to be impacted by the growing concerns regarding environmental imbalance caused by excessive harvesting.

The market production of seaweed is also impacted significantly by the weather conditions of the significant harvesting economies. The production volume is also affected by weather disturbances such as El Nino. Seaweed harvest volume in the Philippines registered a decline in 2016 due to elevated water temperatures caused primarily by El Nino. The high dependence of the alginates market on seaweed production is likely to result in restrained market growth over the forecast period.

An increase in the production of seaweeds from aquaculture has given rise to concerns regarding environmental degradation. High demand for seaweed by manufacturers involved in the production of carrageenan, agar-agar, and alginate leads to increased harvesting of seaweed, which causes an ecological imbalance. Concerns regarding the negative impact of unsustainable farming are also projected to result in limited growth of seaweed, which is, in turn, anticipated to lead to higher pressure on the alginate market in the coming years.

Market Opportunities

Growing demand in the pharmaceutical sector to create new opportunities

Alginate is used as an emulsion stabilizer, thickening agent, disintegrant, and film-forming agent for tablets in the pharmaceutical industry. The rising demand for alginate in the coating of tablets is expected to fuel product demand over the forecast period. In compounded medicines, sodium alginate acts as a capsule disintegrant and stabilizing, suspending, emulsifying, gel-forming, and viscosity-increasing agent. The product is an FDA-approved natural polymer and is gaining high significance in drug manufacturing because of its low or nontoxic nature, biocompatibility, and biodegradability.

Due to advances in science and technology, the pharmaceutical business has been growing in recent years. This trend is expected to continue in the coming years, particularly in developing countries like China, India, and Brazil. In the global pharmaceutical market, these economies have huge market potential. BRICMT countries, namely Brazil, Russia, India, China, Mexico, and Turkey, and the second-tier countries in Southeast Asia and Africa have shown strong economic growth in the past few years. These countries are transforming into markets comparable in size and nature to their mature Western counterparts. At the same time, these economies are also becoming increasingly stable, making them even more attractive for multinational companies to set up their production facilities and invest there. The rise in pharmaceutical exports from these countries is expected to boost the consumption of alginate products over the forecast period.
