Although it contains nearly
half the fat of
semi-skimmed, 1% milk
retains the same amount of
calcium and vitamin B as
semi-skimmed and skimmed
milk. Calcium from dairy is
better absorbed than any
other source of calcium and
a 200ml glass of 1% milk can
provide an adult with
over 1/3 of his or
her daily calcium
requirement. As well as
these nutritional benefits
and a reduction in fat,
Sainsbury's and its
suppliers have worked to
ensure that 1% milk retains
the creamy flavour of
semi-skimmed milk.

ENERGY OF skimmed milk
powder
Large amounts of energy are
expended in the process of
removing water and so plants
developed over the years
have become increasingly
more energy efficient.
Evaporators are much more
energy efficient than
driers, using only a
fraction of a kilogram of
steam (or the energy
equivalent) per kilogram of
water removed. Driers on the
other hand use several
kilograms of steam (or steam
equivalent) per kilogram of
water evaporated. Spray
drying provides a means of
rapidly and gently removing
the bulk of the remaining
water but, ideally, spray
driers have short residence
times.
