Locust (Carob) Bean Gum

What It Is

Locust Bean Gum (LBG) is a Natural food additive derived from the carob tree (Ceratonia siliqua), prevalent in the Mediterranean region. The elongated pods of carob tree are coarsely ground, then separated as two fractions, pulp and seed. Locust bean gum, or LBG, is derived from the endosperm of the seed fraction. Product grades are determned by water viscosity, powder color/purity and particle size.

Chemistry and Structure

The chemical structure of locust bean gum consists of linked sugar units—specifically two hexose sugars (sugars containing six carbon atoms), mannose and galactose, in a ratio of about 4 to 1. LBG may be chemically described as galactomannan, similar to Tara and Guar gums.

Properties

Locust Bean Gum by itself is an effective thickener and water binder that requires heat for complete solution. LBG come in various viscosity ranges and clarity ranges. The differences in clarity are primarily due to color and the presence of “black specks” in the powder which are present from teh seed hulls in LBG processing. The solutions and gels are cloudy due to the presence of cellulose in standard LBG. “Clear” or transparent LBG can be made by removing the cellulose component.

LBG exhibits notable synergies with certain other hydrocolloids such as Kappa Carrageenan and Xanthan Gum. Ask our technical staff for more information today!

 

Typical Applications

ice-cream3

Ice Cream: LBG functions as a water binder to control ice crystal formation while maintaining a smooth creamy texture. Normally used in combination with emulsifiers and other gums such as Carrageenan.

Bagel with Cream Cheese

Cream Cheese: LBG provides body, smooth texture and prevents syneresis. May be used in combination with Xanthan Gum and/or Guar Gum.

Water Gel Desserts: LBG can be used with Carrageenan to produce vegetable-based, gelatin-like desserts that do not require refrigeration. Can be used in either powder mixes or shelf-stable Ready to Eat products.

CHEESE SPREAD

Cheese Spreads: LBG provides a creamy texture and controls syneresis while improving freeze-thaw stability.
