Worked Solution & Example Answer:Outline the importance of including red meat in a teenager's diet - Junior Cycle Home Economics - Question 2 - 2018
Step 1
Part (a) State the importance of including red meat in a teenager's diet.
Answer
Including red meat in a teenager's diet is crucial for several reasons:
-
Protein Source: Red meat is an excellent source of protein, which is essential for growth and development during the teenage years.
-
Energy: It contains saturated fats that provide energy, which is vital for active teenagers.
-
Vitamins: Red meat is rich in B group vitamins that aid in metabolism and energy release from food.
-
Iron Content: It is a significant source of iron, which is important for the formation of red blood cells, helping to prevent anemia, particularly in active teenagers.
-
Bone Health: Red meat is a good source of calcium and phosphorus, both necessary for healthy bone development.
-
Digestibility: Red meat is easier to digest compared to some other protein sources, making it suitable for a growing body.
-
Lack of Carbohydrates: It is also beneficial as it does not contain carbohydrates, which is important for specific dietary needs.
Step 2
Part (b)(i) State the causes of toughness in meat.
Answer
The causes of toughness in meat include:
-
Age: Older animals tend to produce tougher meat due to the development of muscle fibers over time.
-
Activity: Highly active animals develop more muscle tissue, which can lead to tougher cuts of meat.
-
Incorrect Hanging: Improper hanging techniques after slaughter can affect the tenderness of the meat.
-
Incorrect Cooking: Cooking meat at very high temperatures or for too long can result in toughness.
Step 3
Part (b)(ii) List four methods that could be used to tenderise meat.
Answer
Four methods to tenderise meat include:
- Mincing: Breaking down the muscle fibers through cutting.
- Pounding: Physically breaking the fibers with a mallet.
- Piercing: Making small holes in the meat with a fork to allow marinades to penetrate.
- Using Chemical Tenderisers: Applying enzymes or commercial tenderisers can help break down tough fibers.
Step 4
Part (c)(i) Plan and set out a two course dinner menu, to include meat, suitable for a family.
Answer
Menu Plan
First Course: Vegetable Soup
- Description: A warm and hearty vegetable soup made from seasonal vegetables.
- Cooking method: Simmered and pureed.
Second Course: Grilled Chicken with Roasted Vegetables
- Description: Marinated grilled chicken served with a side of roasted seasonal vegetables.
- Format: Served on a plate, balanced with protein and vegetables.
Step 5
Part (c)(ii) Give reasons for your choice of foods.
Answer
- Nutrition: The menu includes a balance of protein from the chicken and vitamins from the vegetables.
- Availability: All ingredients are readily available in local markets, ensuring freshness.
- Seasonal Foods: Using seasonal vegetables not only enhances flavor but also supports local farmers.
- Family Preferences: The meal choices consider common likes and dislikes within a family setting.
Step 6
Part (d) Explain the effects of cooking on meat.
Answer
Cooking meat causes several changes:
- Protein Coagulation: Proteins denature and coagulate, altering the texture.
- Fat Melting: Fats melt, adding flavor and juiciness to the meat.
- Color Changes: The meat changes color; for example, it turns from red to brown, indicating it's cooked.
- Flavors Develop: The cooking process enhances the flavor profiles through the Maillard reaction.
- Micro-organisms Destroyed: Cooking at the right temperatures kills harmful bacteria, making the meat safe to eat.
Step 7
Part (e) What information does the following symbol convey to the consumer when purchasing meat?
Answer
The symbol conveys that the meat is produced and processed according to the quality assurance scheme of Bord Bia. This logo ensures that the meat meets specific quality standards, providing consumers with assurance regarding its safety, traceability, and welfare of the animals.
