Kappa

S tier

Kappa carrageenan is the firm, brittle gelling fraction extracted mainly from farmed Kappaphycus. Potassium ions lock the chains into a sliceable gel that chocolate milk processors, processed-cheese makers, and dessert plants rely on to suspend cocoa and hold a clean cut. Alone it can synerese—weep water—so it is often blended with iota or a locust-bean partner when a less brittle bite is wanted. Hydrate with heat; the gel sets on cooling and is not a cold-thicken-and-forget gum. Flavour is nearly none when the powder is well refined. Choose kappa when you need structure, not silk: flan-style dairy desserts, meat brine bite, and cocoa suspension. Lambda will not gel; iota will bounce. Wrong ion (too much calcium, too little potassium) gives a weak or grainy set.
