What else do I need to make caviar pearls and boba spheres with sodium alginate?

You need a calcium salt (calcium chloride for direct spherification, calcium lactate for reverse). We sell value packs with both ingredients included plus step-by-step instructions. Free video tutorials on our Kitchen Alchemy YouTube channel.

How do I know this sodium alginate is truly food-grade and safe to use in cooking?

Every batch is Non-GMO, Vegan, and OU Kosher Certified with full technical specs (viscosity, mesh size). We provide Certificate of Analysis, Safety Data Sheet, and Product Spec upon request. Our certifications are verified — not just label claims.

Can I use sodium alginate for anything besides making caviar pearls and boba?

Absolutely. Use it as a natural thickener for pie fillings, sauces, and dressings. Make keto noodles, improve ice cream texture, or create culinary foams. Beyond cooking, it's popular for tie-dye fabric art, bath bombs, and STEM science experiments.

How much sodium alginate do I need, and how long does it last once opened?

A little goes a long way — one 50g pouch makes about 17 cups of spherification solution. Stored sealed in a cool, dry place, it lasts practically indefinitely. Each pouch is resealable. Most home cooks find the 50g size gives months of experimenting.

Can sodium alginate help with acid reflux, GERD, or LPR (laryngopharyngeal reflux)?

Sodium alginate is known for forming a "raft" that floats on stomach contents, which may help manage reflux symptoms. This is a food-grade ingredient, not a supplement or medication. Consult your doctor for medical advice about GERD or LPR treatment.
