title: Heat stability in concentrated and non-concentrated milks--the effect of urea and beta-lactoglobulin levels and the influence of preheating.
abstract: Heat stability as a function of pH has been studied in concentrated and non-concentrated milk systems. The influence of preheating has also been examined. The concentration of beta-lactoglobulin has been shown to affect markedly the heat stability behaviour in both systems but with different characteristics. Increasing the level of urea resulted in increased heat stability in non-concentrated milks, but corresponding concentrated milks showed a small decrease in maximum heat stability. It has not been possible to extrapolate heat stability data from non-concentrated to concentrated milks.
