REHYDRATION KINETICS AND STABILITY OF MILK POWDER

INTRODUCTION In dairy industry, milk is often dehydrated. Indeed, milk powder has a longer shelf life than liquid milk, does not require refrigeration and as a result is easier to transport. However, dehydration must not alter milk properties; consequently, it is important to check if the rehydrated milk has the same properties than the native milk. Another aspect is to measure the rehydration kinetics in order to optimize rehydration process. In this note, we propose a method to assess the kinetics and the efficiency of rehydration of milk powder. The stability of rehydrated milk powder is also assessed.
