Abstract
Abstract A gellable composition comprises a mixture of (1) gellan, (2) xanthan gum, and (3) a galactomannan and/or glucomannan gum capable of producing a gel in combination with xanthan gum, especially carob, tara, cassia or konjac gum, wherein the ratio by weight range of (1):[(2)+(3)] is 1:>/=2.
