What is it?
konjac, konjac gum, konjac glucomannate (INS 425) is a Carrier, Emulsifier, Gelling agent, Glazing agent, Humectant, Stabilizer, Thickener food additive. Used to carry, dilute or stabilise other additives or nutrients for easier dispersion and addition.Allows immiscible liquids (e.g. oil and water) to form a stable uniform system, improving texture.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.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. maltodextrin, glycerol, vegetable oil.Some derive from natural raw materials (e.g. soy lecithin, egg-yolk phospholipids).E.g. pectin, agar, carrageenan, gelatin.E.g. beeswax, carnauba wax, shellac.Mostly naturally occurring polyols (e.g. glycerol, sorbitol).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：Including modified starches.Many are made by esterifying glycerol with fatty acids or further derivatisation (e.g. monoglycerides, spans, tweens).Extracted and purified.Purified.Produced by hydrogenation or fermentation processes.Some are physically or chemically modified (e.g. carboxymethyl cellulose, modified starches).Some are modified for performance (e.g. hydroxypropyl starch, CMC).

Safety
Mostly common food matrices, safe within permitted use.Largely metabolised in the gut; generally safe within permitted use; JECFA sets ADI where applicable.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.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
