Worked Solution & Example Answer:Name three different methods of processing used to make milk safe for consumption - Leaving Cert Home Economics - Question 5 - 2008
Step 1
Name three different methods of processing used to make milk safe for consumption.
Answer
-
Pasteurisation: This process involves heating milk to a specific temperature for a set period, killing harmful bacteria while preserving the milk's quality.
-
Sterilisation (Ultra Heat Treatment): Milk is heated to a very high temperature (usually above 135°C) for a short duration. This method ensures that any microorganisms are eliminated and extends shelf life.
-
Dehydration: This method removes moisture from milk, creating a powder form. The lack of water inhibits the growth of bacteria, making it safe for long-term storage.
Step 2
State the benefit to the consumer of adding bacterial cultures, such as acidophilus, to bio-yoghurt.
Answer
Adding bacterial cultures like acidophilus to bio-yoghurt provides the benefit of aiding digestion. These beneficial bacteria help enhance gut health by improving digestion and potentially alleviating digestive issues.
