At the Plant
Milk contains about 4% fat when it leaves the
farm. At the plant, the milk is subjected to a
standardization process to adjust the fat content
to the type of milk required.
The next step is pasteurization. The
process involves heating the milk for a
period of time depending on the heating
temperature. For example, if the milk is
heated at 72°C -75°C, the process will
take only 16 seconds. The milk is then
quickly cooled to under 4°C.
Pasteurization destroys harmful micro-
organisms and prolongs the storage
period, while preserving the natural \r
taste and nutritional value of milk.
milk
UHT milk (ultra-high temperature) is milk that
has been pasteurized at a very high tempera-
ture.
A brief comparison with other nutritious foods
illustrates just how nutrient -dense milk really is:
• As much protein as a large eggs A Single cup
or 250 ml of Whole Milk contains
• as much calcium as seven medium
sardines with their bones.
For obvious health reasons, all dairy products
must be pasteurized before being sold, with the
exception of raw milk cheese. Regulations pro-
vide for a 60 -day ripening period, which makes
it fit for consumption.
The next step after pasteurization is homoge-
nization. This process splits fat cells into fine
particles that are distributed uniformly through-
out the milk, thus preventing the fat from rising
to the surface.
Fluid Milk
In Canada, fluid milk is pasteurized and homog-
enized before being sold. Vitamin D is added to
fluid milk because it facilitates calcium absorp-
tion. All forms of skim milk - liquid, evaporated
or powder - contain vitamin A, in addition to
vitamin D.
Milk contains about 4% fat when it leaves the
farm. Part of the cream is removed at the plant
to make the four types of milk on the market:
homogenized milk containing 3.25% fat, partly
skimmed milk with 2% and 1% fat, and skim
This
process
consider-
ably extends the shelf life of milk without alter-
ing its nutritional value. UHT milk can be kept
up to three months after the treatment date. No
refrigeration is needed before the container is
opened.
Microfiltered milk is processed according to a
microfiltration process that eliminates bacteria,
making it possible to pasteurize milk at a lower
temperature.
This process gives a type of milk that is creami-
er and has a longer shelf life than traditional
milk, i.e., 30 days compared to 18 days.
Are All Types of Milk Equally
Nutritious?
Skim, 1%, 2%, whole or homogenized milk,
chocolate milk and powdered skim milk give
you basically the same amount of vitamins and
minerals. Milk is also 90% water, making it an
effective thirst quencher.
• More thiamin, riboflavin and niacin than
a slice of 100% whole wheat bread
• Almost as much potassium as a banana
• Half the cholesterol of 100g of Haddock
• Close to 3/4 of vitamin A in 125 ml of broccoli
• Less fat than a 1/4 pound of lean ground beef
• About 50% of the vitamin D adults under 50
years old need, daily.
What Is the Nutritive Value of Chocolate Milk?
Chocolate milk contains the same nutrients as
plain milk, a negligible amount of caffeine and
no more carbohydrates (sugar) than a glass of
unsweetened apple or orange juice.
Is chocolate milk bad for teeth?
The answer is no. Since choco-
late milk is a liquid, its sugar
doesn't stay in the
mouth very long or
cling to the surfaces of
our teeth. Also, both
cocoa and the positive
tooth -building nutri-
ents in milk offset the
effect of chocolate
milk's sugar content.
