Question

question 29.
which moist heat cooking method would best preserve the nutrient content of food?
a. ○ boiling
b. ○ steaming
c. ○ roasting
d. ○ braising

Explanation:

To determine the best moist - heat cooking method for preserving nutrients:

1. Analyze Option A (boiling): Boiling involves submerging food in boiling water. A significant amount of water - soluble nutrients (such as vitamins B and C) leach out into the cooking water, so it is not good for nutrient preservation.
2. Analyze Option B (steaming): Steaming uses steam to cook food. Since the food is not in direct contact with a large amount of water, water - soluble nutrients are less likely to be lost. Also, the cooking time is relatively short, which further reduces nutrient degradation from heat exposure.
3. Analyze Option C (roasting): Roasting is a dry - heat cooking method (using hot air), so it is not a moist - heat method and is eliminated.
4. Analyze Option D (braising): Braising involves cooking food in a small amount of liquid at a low temperature for a long time. The long cooking time can lead to more nutrient breakdown, and some nutrients may leach into the liquid.

Answer:

B. steaming
