Name______________________________________________ Date_________________________ Activity: Determining Types of Heat Transfer Cooking methods rely on dry heat, moist heat, and combination heat. Depending on the method used, heat transfer occurs through conduction, convection, or radiation. Conduction uses direct physical contact to transfer heat. Convection uses a medium surrounding the food such as hot air, hot water, or hot fat to transfer heat.

Radiation transfers heat through heat waves.

Identify the type of heat used (dry, moist, or combination) and explain how heat is transferred (conduction, convection, or radiation) for the following cooking methods. ������������������ 1. Poaching uses ___ heat. ������������������ 2. When poaching, heat is transferred through ___. ������������������ 3. Grilling uses ___ heat. ������������������ 4.

Activity: Analyzing Cooking Effects When heat is introduced to food through the cooking process, characteristics of the food begin to change. Proteins, carbohydrates, fats, vitamins, minerals, and water content are altered when exposed to heat and this can cause a change in the weight, color, texture, or flavor of the food.

Obtain two chicken breasts and weigh each one.

1. How much does each chicken breast weigh?

Roast both chicken breasts in a 325°F oven until an internal temperature of 165°F is met. Slice one chicken breast immediately into ½-inch slices. Weigh the slices from the sliced chicken breast.

2. How much does the sliced chicken breast weigh after cooking?

Allow the second chicken breast to rest for 5 minutes. Weigh the whole chicken breast after the rest period.

3. How much does the unsliced chicken breast weigh after cooking?

4. Why is there a difference in weight between the two chicken breasts?
