Food Processing

How food is preserved and processed

Why We Process Food

Food processing changes raw food into products that last longer or taste better. Without processing, many foods would spoil quickly. Methods include drying, canning, freezing, smoking and adding preservatives.
Example

Food Processing Examples in SA

• Milk → pasteurised → cheese or yoghurt • Fruit → dried in the sun → dried fruit (raisins, mango) • Maize → milled → mealie meal • Meat → salted and dried → biltong • Tomatoes → cooked and sealed → tinned tomatoes
Note

Remember

Processing helps food last longer (preservation). Always check food labels for expiry dates, ingredients and nutritional information. Some processed foods have too much sugar, salt or fat — fresh foods are often healthier.
