What is it?
calcium alginate (INS 404) is a Antifoaming agent, Bulking agent, Carrier, Foaming agent, Gelling agent, Glazing agent, Humectant, Sequestrant, Stabilizer, Thickener food additive. Used to suppress or eliminate undesirable foam during food processing.Used to increase bulk or replace sugar/fat to provide body, usually low-calorie.Used to carry, dilute or stabilise other additives or nutrients for easier dispersion and addition.Used to generate or stabilise foam, improving texture and mouthfeel.Used to form gels or semi-solid structures in liquid foods.Used to form a protective coating on food surfaces, improving appearance and preventing moisture loss.Used to retain moisture and prevent foods from drying out and hardening.Binds metal ions to prevent oxidation, discolouration or deterioration catalysed by metals.Used to keep the physical state of foods stable, preventing separation, sedimentation or syneresis.Used to increase viscosity and improve mouthfeel and body.
Source
Natural：E.g. polydimethylsiloxane, animal/vegetable oils, fatty acid esters.E.g. dietary fibres, polyols, modified starches.E.g. maltodextrin, glycerol, vegetable oil.E.g. soy protein, lecithin, gelatin.E.g. pectin, agar, carrageenan, gelatin.E.g. beeswax, carnauba wax, shellac.Mostly naturally occurring polyols (e.g. glycerol, sorbitol).E.g. citric acid and its salts occur naturally in citrus fruits.Mostly natural gums, proteins or polysaccharides (e.g. gelatin, pectin, locust bean gum).Mostly natural polysaccharides or proteins (e.g. pectin, xanthan, carrageenan, starch).
Industrial：Purified.Processed.Including modified starches.Purified or modified.Extracted and purified.Produced by hydrogenation or fermentation processes.Synthesised from the corresponding acids or salts (e.g. EDTA salts, phosphates).Some are physically or chemically modified (e.g. carboxymethyl cellulose, modified starches).Some are modified for performance (e.g. hydroxypropyl starch, CMC).

Safety
Mostly inert, non-absorbable with very low residues, safe within permitted use.Mostly indigestible carbs or sugar alcohols, safe within permitted use.Mostly common food matrices, safe within permitted use.Mostly food proteins or polysaccharides, safe within permitted use.Mostly natural polysaccharides or proteins, safe within permitted use.Safe within permitted use, generally non-digestible.Safe within permitted use; excess sugar alcohols may have a laxative effect.Safe within permitted use; excessive phosphate intake may affect calcium–phosphorus balance.Most act as dietary fibre or inert colloids and are safe within permitted use.Mostly indigestible polysaccharides, safe within permitted use; some act as dietary fibre.
Metabolism：Metabolic pathways vary by substance; generally the material is metabolised or excreted normally.
Concerns：
- Use within permitted levels
- Sensitive individuals should check the ingredient list
