ABSTRACT:
A process for manufacturing a treated polyuronic acid. The process involves heating an aqueous dispersion of a polyuronic acid, such as a pectin, at a temperature above about 100.degree. C. for an amount of time sufficient to obtain a hydrolyzed, or treated, polyuronic acid mixture which separates upon standing and cooling into a clear solution, which is the hydrolyzed polyuronic acid phase, and a precipitate. The hydrolyzed polyuronic acid phase includes at least 25% of the polyuronic acid substance polymers having a degree of polymerization (DP) in the range of about DP1 to about DP20. The hydrolyzed polyuronic acid, or the treated polyuronic acid, then is recovered for use in a food product.
