Purpose To inform the audience of the detailed process of

milk powder production. To expose to the audience on how does

converting milk into milk powder helps inpreserving food and making its shelf life longer

for consumers.

Objective Differentiate the nutritional values of two kinds of

dairy products, namely milk and milk powder. Raise the health awareness of the audience.

Exposed to the basic working principle andtheory behind the production of milk powder.

1. Pasteurization:

Pasteurization or pasteurisation is a process of

heating a food, which is usually a liquid, to a specifictemperature for a predefined length of time and then

immediately cooling it after it is removed from the

heat. This process slows spoilage caused

by microbial growth in the food.

2. evaporation:

Generally means to convert from liquid phase to vapor

phase, or to draw moisture from, as by heating,

leaving only the dry portion. This concept is usedin the production of milk powder, whereby

powdered milk is a manufactured dairy product

made by evaporating milk to dryness, reducing its

moisture content.

3. spray-drying:

Dried by bringing a sprayed substance(usually in

liquid form) into contact with hot air and

recovering it in the form of a powder. All spray

dryers use some type of atomizer or spray nozzle to

disperse the liquid or slurry into a controlled drop

size spray.

advantages: Longer shelf life

Reduce the weight and volume of the product

Lower the cost of transportation

Modified to contain certain vitamins for targeted

growth

Disadvantages: Less thick than raw milk

Processed, contains preservatives

fun facts!!Most cows give more milk when they listen to

music.

Milk is better for cooling your mouth after eating

spicy food.

The most precious kind of milk is mothers milk.

This nourishes new-born babies until they are old

enough to be weaned onto other foods.

From birth to old age, theres no better recipe for

a good nights sleep: a nice glass of warm milk.

conclusion: 3 major steps are involved in the milk powderproduction, namely pasteurization, evaporation,

and spray drying.

Preserves food quality and lengthens shelf life.

Carried out in large scales in modern society.

Safety concerns regarding the effectiveness of itsadditives are still raised.
