Commercial locust bean gum is the ground endosperm of the seeds of the locust bean (carob) tree. The general properties of locust bean gum are similar to those of guar gum. Differences are its low cold-water solubiUty and its synergistic gelation with kappa-carrageenan, furceUaran, and xanthan...

The patent literature pertaining to the industrial exploitation of guar gum from 1948 to 1962 has been comprehensively collated by Saxena,34 and will not be considered here. Saxena s compilation34 covers more than 70 patents relating to 15 industries, and includes gum extraction and purification, and modification of gum properties. A selection, taken from the literature over the past decade or so, of applications of galactomannans is given in Table VI. It may be seen that guar gum is, indeed, a versatile product. Some of the more im-... 

The regression analysis of the power law models for 0.75 and 1.0% guar gum suspensions returned R2 values exceeding 0.99 and are shown in Table 3. The power law model was an accurate representation of guar gum rheologic properties.

Perhaps the most outstanding and unusual property of xanthan gum is the reactivity with galactomannans such as locust bean gum, (10) and guar gum (3 ). ... 

The molecular weight of the galactomannan is close to 310kdal. Physical properties correspond to those of guar gum, except the viscosity of the solution is not as high (cf. Table 4.21).

Food-grade locust bean gum is a white to yellowish white, nearly odorless powder. Many of its physical properties are similar to those of guar gum, but unlike guar gum it is not...
