The invention relates to the use of polygalacturonides as food additives,
said polygalacturonides being obtainable via the following process steps:
a) a pectinous plant material is subjected to a pectin extraction in
aqueous solution;
b) the solids are removed from the suspension obtained in step a),
consisting of liquid phase including dissolved pectin and solids from the
plant material;
c) the pectin is precipitated from the liquid phase obtained in step b);
d) the pectin obtained in step c) is dissolved in an aqueous solution and
cleaved with purified endo-polygalacturonase;
e) the polygalacturonides obtained in step d) are processed into a
polygalacturonide preparation without using an additional separation step
and without hydrolyzing ester groups that are present.
