Anwendungen & Verwendung
Verwenden
Sodium tripolyphosphate is a binder, stabilizer, and sequestrant that is mildly alkaline, with a pH of 10, and moderately soluble in water, with a solubility of 15g in 100ml of water at 25°C. It is used to improve the whipping properties of egg-containing angel food cake mix and meringues. It reduces gelling of juices and canned ham and tenderizes canned peas and lima beans. It is a moisture binder in cured pork and protects against discoloration and reduces shrinkage in sausage products. In algin desserts, it functions as a calcium sequestrant. Sodium tripolyphosphate is also termed pentasodium tripolyphosphate and sodium triphosphate.
