Freshly delivered pasteurised homogenised milk samples with
different fat contents were obtained from a local dairy processor
and processed on the same day. Compositional and other data on
these milks (measured as described in 2.4 and 2.5 below) are shown
in Table 1. A two stage homogenizer (150 bar first stage, 50 bar second
stage) was used to homogenize the milks giving a mean fat globule
size of 0.4 lm (max. 2 lm for unhomogenised full cream milk)
and milks were pasteurised (72 C, 15 s) within 12 h of collection.
