Description and Uses

Locust Bean Gum is a gum that is a galactomannan obtained from the plant seed from the locust bean tree known as ceratonia siliqua. it has a mannose:galactose ratio of approximately 4:1. its properties include swelling partially in cold water but requiring heating to approximately 82°c for complete solubility. it provides high viscos- ity, forms gels with xanthan gum upon heating and cooling of the solution, and functions as a water binder. it can make agar or car- rageenan gels more elastic. its uses include processed cheese, ice cream, bakery products, soups, and pies. typical usage level is 0.1– 1.0%. it is also called carob gum or saint john’s bread, and is scien- tifically called carubin.
