Abstract

The invention relates to an Arabic gum molecular weight grading method, particularly to a method for accurately regulating and controlling Arabic gum molecular weight grading by utilizing maltodextrindegradation. The method comprises the following steps: degrading maltodextrin; respectively mixing the degraded maltodextrin with Arabic gum in water, fully stirring and mixing to respectively form corresponding mixed aqueous solutions, and standing for 24-48 hours until phase separation is completely stopped; establishing a relation model of maltodextrin with different molecular weights and Arabic gum component contents, and realizing accurate regulation and control of Arabic gum molecular weight grading according to the model.

Description

technical field [0001] The invention relates to a method for grading the molecular weight of gum arabic, in particular to a method for precisely regulating the molecular weight grading of gum arabic by utilizing maltodextrin degradation. Background technique [0002] Phase separation technology is widely used in the food field. The isolated phase separation behavior of natural food polymers is mainly manifested as two or more natural polymers with the same charge or neutrality. Thermodynamic instability under the action of repulsion or electrostatic repulsion. After the segregation-type phase separation behavior occurs, the system will form two different enriched phases, each of which is rich in one polymer but also contains a small amount of the other polymer. Liquid-liquid isolation type phase separation induces the fractionation of gum arabic components without any change in the natural chemical structure of each component of gum arabic, which is a new type of green gum ...
