STAERKELSEDERIVAT SOM BILDAR REVERSIBLA GELER. |
摘要 |
The invention provides modified starches having unique gelling properties which are prepared by chemically reacting an amylose containing starch base with an etherification or esterification reagent which will introduce a long linear hydrocarbon chain substituent therein. The aqueous gels formed by the starches are thermally and pH-reversible and the thermally-reversible gels are hot gels. The invention further provides an improved process for preparing starch halfacid esters in water by reacting starch under alkaline conditions with a hydrophobic-substituted cyclic dicarboxylic acid anhydride in the presence of a phase transfer agent. |
