Formation of deposits by milk salts and whey proteins during evaporation of whey and ultrafiltration permeate in a falling-film evaporator - Ansatzbildung durch Milchsalze und Molkenproteine beim Eindampfen von Molke und Ultrafiltrationspermeat in einem Fallfilmverdampfer

A specially developed evaporator was used to study deposition during evaporation of ultrafiltration permeate, whey and whey concentrate. Deposition from permeate was caused by crystallization of Ca3(PO4)2 and decreased at low pH. Deposition from whey was primarily dependent on whey protein denaturation, but as whey concn. increased the effect of crystallization became more important and the proportion of salts in deposits increased.
