Locust bean or guar? Molecular methods for detecting additions of guar gum to locust bean gum
Notes:
This work was presented at the annual meeting of the Institut EuropÈen des Industries de la Gomme de Caroube (INEC) hold in Granada, Spain.
It describes the preexisting methods for discriminating between the locust bean gum (LBG)and guar gum, two gellifier agents extracted from the carob tree (Ceratonia siliqua) and the guar plant (Cyamopsis tetragonolobus or C. tetragonoloba).
The interest in this discrimination comes from the different prices of the two additives, the LBG being more expensive than the guar gum.
