Schnell auflösendes, nicht zusammenbackendes Natriumtripoly-phosphat für Nahrungsmittel.

摘要

A fast-dissolving, non-caking, food grade sodium tripolyphosphate is produced by spraying into a spray dryer an aqueous sodium orthophosphate feed liquor having an Na2O:P2O5 ratio of from about 1.60 to about 1.67 containing potassium hydroxide or a soluble potassium salt in amounts to yield about 0.4% to 0.8% by weight potassium in the final product, heating the feed to at least 440C to form sodium tripolyphosphate, cooling the sodium tripolyphosphate and adding to it at least about 1% by weight moisture.
