Gellan gum fluid gels: influence of the nature and concentration of gel-promoting ions on rheological properties
(Springer, 2018-11)
Low-acyl gellan gum fluid gels were obtained using two different gel-promoting cations under the same processing conditions, and their rheological properties were investigated. For that reason, stress and frequency sweep ...
