How to Mix Locust Bean Gum

Locust Bean Gum is a thickening and gelling agent supplied as a powder. There are different grades available depending on the end user’s desired gel strength, particle size and clarity.
Locust bean gum is often used in combination with other hydrocolloids, typically agar, xanthan and carrageenan, especially where higher viscosities are required. For example, blends of xanthan and locust bean gum will form a gel with properties that cannot be achieved with either ingredient alone.
Locust Bean Gum begins to hydrate as soon it is added to water, and if the powder is not dispersed into the water quickly enough agglomerates or “fish eyes” will form. Even when steps are taken to prevent the formation of agglomerates, such as premixing with other ingredients, agglomerates can easily form. This can be exacerbated by operator error. Agitators do not produce sufficient shear to rapidly break these down, leading to long mixing times and low yield.
In this video, see how Silverson High Shear Mixers are able to achieve an agglomerate-free Locust Bean Gum mix.
