Widely used in molecular gastronomy, it enables chefs and home cooks alike to create gel-like textures, liquid spheres, and stable emulsions. Beyond cooking, it doubles as an effective dye thickener, offering versatile applications with precise control. Trusted by professionals and DIY enthusiasts, this premium powder delivers long-lasting performance and exceptional value. ## Description From wikipedia: as a flavorless gum, it is used by the foods industry to increase viscosity and as an emulsifier. As a food additive, sodium alginate is used especially in the production of gel-like foods. For example, bakers' "chellies" are often gelled alginate "jam." also, the pimento stuffing in prepared cocktail olives is usually injected as a slurry at the same time that the stone is ejected; the slurry is subsequently set by immersing the olive in a solution of a calcium salt, which causes rapid gelation by electrostatic cross-linking in recent years, sodium alginate has been used in molecular gastronomy. Ferran adriΛ† pioneered the technique, and it has since been used by chefs such as grant achatz and heston blumenthal. Sodium alginate is combined with calcium lactate or similar compounds to create spheres of liquid surrounded by a thin jelly membrane. Review: Effective home remedy for LPR - The product arrived quickly and was as advertised. I thought I'd try sodium alginate after reading that it's the main ingredient of Gaviscon Advance. Several studies have indicated that Gaviscon Advance (G.A.) is the most effective treatment for LPR. (Disclaimer: I'm not a doctor) Since it's only sold in Europe, G.A. is difficult and costly to acquire in the States. My DIY version is simple: about a 2:1 ratio of sodium alginate to baking soda in a small amount of water. That's about 1/8 tsp sodium alginate in 1 tablespoon of water. I have to add the sodium alginate very slowly to the liquid, as it globs easily. I use a shot glass, and stir rapidly with a chop-stick while shaking the powder in. Then I let sit for at least half an hour to fully gel up. Ideally, it should be about the consistency of molasses. I take it just before bed, and other times as needed. Along with avoiding acid foods and eating smaller portions, sodium alginate has effectively controlled my symptoms of LPR and related cough. It's a good product, and 4 oz. has lasted a long time. I'll be reordering soon. Review: Great for dye thickening when tie dying - This works great for a dye thickener. I have used super clear from Dharma and it did not thicken. This product i am pleased it can be adjusted easily to thickness. I would definitely purchase again for the cost. You get 15 times as much as one container of super clear that is 5.99 for a jar. Super clear cannot be thickened as this can be. Don't be bummed by the size of package when you open it. It is much smaller than it appears. It only requires a small amount. I didnt mix powder with it, I mixed it with water in a mixer, preferrably a beverage blender with a lid. You can do it by hand but it is a long process. This is a great product for dye thickening. ## Features - Flavorless gum - For increasing viscosity and as a emulsifier - Used to make gel-like foods (i.e. Bakers "chellies") - Molecular gastronomy - Powder form ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00LLO6FSK | | Best Sellers Rank | #263,653 in Grocery & Gourmet Food ( See Top 100 in Grocery & Gourmet Food ) #40 in Alum Thickeners | | Brand | greenoak | | Brand Name | greenoak | | Customer Reviews | 4.6 out of 5 stars 267 Reviews | | Flavor | Unflavored | | Item Form | Powder | | Manufacturer | The Seaweed Solution | | Manufacturer Part Number | BJ-WT5U-87X6 | | Number of Items | 1 | | Primary Supplement Type | Calcium | | UPC | 609408037153 | | Unit Count | 4 ounce | ## Product Details - **Brand:** greenoak - **Flavor:** Unflavored - **Item Form:** Powder - **Primary Supplement Type:** Calcium - **Unit Count:** 4 ounce ## Images ![Sodium Alginate - Food Grade - 4 Ounces - Image 1](https://m.media-amazon.com/images/I/81Z8VopY9GL.jpg) ## Questions & Answers **Q: Is this a powder?** A: Yes, it is in powder form. **Q: Do you sell food grade magnesium alginate or food grade calcium alginate?** A: Hello- I do have food grade calcium alginate available here: https://www.amazon.com/dp/B07CM8TJPN?ref=myi_title_dp I do not carry magnesium alginate. **Q: what country makes this?** A: Don't know the country that makes this.

Excellent packaging. Excellent product. If you do fabric art and silk painting using the serti technique and you're looking for a replacement for store bought gutta, this is the stuff. 1 teaspoon calcium alginate, mix with 1 teaspoon alcohol, add 1/4 cup HOT water and blend it up. If you don't blend it, you get an unworkable chunky goop. This will wash out in hot water. Makes as strong of a resist line as any water based gutta. ## Frequently Bought Together - Sodium Alginate - Food Grade - 4 Ounces - Wilton Mini Squeeze Bottles, Reusable Plastic Bottles for Candy Melts, Sauces & Baking Decorations, 6 oz., 2-Count - BRIGHTFROM Condiment Squeeze Bottles, 16 OZ Empty Squirt Bottle with Twist Top Cap, Leak Proof - Great for Ketchup, Mustard, Syrup, Sauces, Dressing, Oil, Arts and Crafts, BPA FREE Plastic - 2 PACK --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/7861487-sodium-alginate-food-grade-4-ounces](https://www.desertcart.pt/products/7861487-sodium-alginate-food-grade-4-ounces) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-21*
