Abstract
Disclosed herein is a method for producing modified gum arabic, the method comprising: providing gum arabic; heating said gum arabic, resulting in heat-treated gum arabic; dissolving said heat-treated gum arabic in a solution; optionally, filtering said solution containing said dissolved gum arabic; and subjecting said solution containing said dissolved gum arabic to spray-drying. Further disclosed herein is a gum arabic from Acacia Senegal having (i) a weight average molecular weight (Mw) of ≥3.8·106 Da, and/or (ii) a RMS-radius of gyration (Rg) of ≥140 nm.
Claims18
A method for producing modified gum arabic, the method comprising:
- providing gum arabic;
- heating said gum arabic, resulting in heat-treated gum arabic;
- dissolving said heat-treated gum arabic in a solution;
- subjecting said solution containing said dissolved gum arabic to spray-drying wherein the RMS-radius of gyration (Rg) of the modified gum arabic is at least 140 nm and the weight average molecular weight (Mw) is at least 3.8·106 Da.
A modified gum arabic from Acacia Senegal having an RMS-radius of gyration (Rg) of at least 140 nm and a weight average molecular weight (Mw) of at least 3.8·106 Da.
An emulsion comprising modified gum arabic, an aqueous phase, an oil phase, wherein the gum arabic is used in a weight ratio of gum arabic to oil of less than 1:1.2 and wherein the oil content of the emulsion is at least 15%;
- and the RMS-radius of gyration (Rg) of the modified gum arabic is at least 140 nm and the weight average molecular weight (Mw) is at least 3.8·106 Da.
