What is Sodium Alginate?
Sodium alginate is a natural polysaccharide derived from brown seaweed. It’s a salt of alginic acid, composed of linear copolymers of β-D-mannuronic acid and α-L-guluronic acid. According to the U.S. Food and Drug Administration (FDA), sodium alginate is approved to be used in food.
CAS No.: 9005-38-3
According to the American Chemical Society, the CAS number of sodium alginate is 9005-38-3.
E number: E401
According to the European Food Safety Authority (EFSA), sodium alginate is approved as a thickener (E401) in foods.
Bulk Sodium Alginate Manufacturers
Top sodium alginate manufacturers include some companies in the United States, France, Germany, and China. These sodium alginate manufacturers often have relationships with seaweed farmers or may even own seaweed farms, as brown seaweed is the primary source of alginate.
Sinofi is a bulk sodium alginate manufacturer in China, and we have a manufacturing facility with 2,500 square meters for the production of alginates. We supply high-quality sodium alginate at bulk prices for our clients worldwide.
Manufacturing Process of Sodium Alginate Powder
The manufacturing process for sodium alginate typically involves the following steps:
- Harvesting of brown seaweed.
- Extraction of alginic acid using an alkaline solution.
- Conversion to sodium alginate through neutralization.
- Purification and drying.
Bulk Sodium Alginate Suppliers
Sodium alginate suppliers play a crucial role in ensuring a steady supply of sodium alginate to various food, pharmaceutical, textile, and cosmetics industries. Major suppliers are often located in seaweed-rich regions like China, Japan, and parts of Europe. The top sodium alginate suppliers largely overlap with the major manufacturers, as many companies both produce and distribute sodium alginate E401. However, some companies like Brenntag focus more on sodium alginate distribution. Sinofi is a bulk sodium alginate supplier in China, and we have a warehouse with 1,200 square meters for high-quality sodium alginate powder. We supply different grades of sodium alginate at wholesale prices to various industries around the world.
Supply Chain of Sodium Alginate
The sodium alginate supply chain involves seaweed farming, harvesting, processing, and distribution. Key producing regions include China, Japan, and parts of Europe. The supply can be affected by factors such as seaweed availability, environmental factors, and global demand.
Wholesale and Buy Sodium Alginate in Bulk
If you are buying sodium alginate wholesale, you should determine the grade of sodium alginate required for your application and find a reputable supplier with a technical background. For regular purchases, you can negotiate long-term contracts to secure stable pricing and supply. By approaching procurement strategically, businesses can ensure a reliable supply of high-quality sodium alginate at competitive prices, supporting their operations and product quality.
As a bulk sodium alginate manufacturer and supplier in China, we not only supply high-quality sodium alginate powder to large food manufacturers and pharmaceutical companies worldwide.
