The Gellan gum has two types, the high acyl and low acyl type, the specific difference is as follows:
High Acyl Gellan Gum
High acyl gellan gum can form soft, very elastic, non-brittle gels
Low Acyl Gellan Gum
Low acyl gellan gum can form hard, non-elastic, brittle gels Varying the ratios of the two forms of gellan gum produces a wide variety of texture.
