Specialized Milk Powders

In addition to conventional milk powders,
there is a growing range of powders that are
specially tailored to provide physical, nutri-
tional, or physiological functional roles in a
food product.


Milk Powders for

Chocolate Manufacture

When full - cream milk powder is intended for
chocolate manufacture, a high level of free
fat is desirable to reduce the amount of cocoa
butter and surfactants needed in the chocolate

formulation as the viscosity of the chocolate
mass is reduced and less energy is used for
chocolate manufacture. When the traditional
process is for manufacture of full - cream milk
powder (Figure 6.1 ) with a typical fat content
of 26% fat, a powder with low level of free
fat is obtained. However, roller - dried powders
have high levels of free fat, making them
more suitable for chocolate manufacture
(Reimerdes and Mehrens, 1993 ; Augustin,
2001 ). Compositional factors can impact the
free fat content of milk powder. Higher solid -
fat content of the fat (Twomey et al., 2000 )
or the fat content of the concentrate (Kelly
