TEMPERATURE-CONTROLLED AND PH-DEPENDANT SELF-GELLING BIOPOLYMERIC AQUEOUS SOLUTION |
摘要 |
The present invention relates a biopolymeric liquid aqueous composition for producing self-gelling systems and gels, which comprises: an acidic water- based medium, 0.1 to 10 % by weight of a pH-gelling acid-soluble biopolymer; and 0.1 to 10 % by weight of a water-soluble molecule having a basic character and a pKa between 6.0 and 8.4, or a water-soluble residue or sequence of the molecule having a basic character and a pKa between 6.0 and 8.4. The liquid composition has a final pH ranging from 5.8 and 7.4, and forms a stable solid and homogeneous gel within a temperature range from 10 to 70 ~C. The present invention also relates to a method for preparing the composition and uses thereof. |
