CPM Pie Storage, Shelf Life & Packaging 1 — Questions and Answers
Question 1: What is the maximum safe refrigerator storage time for a cream or custard pie?
- 2 days
- 4 days (Correct answer)
- 7 days
- 10 days
Correct answer: 4 days
Cream and custard pies should be consumed within 3–4 days when stored at 40°F (4°C) or below to prevent bacterial growth.
Question 2: At what maximum internal temperature should a cream pie be held during retail display?
- 45°F (7°C)
- 50°F (10°C)
- 40°F (4°C) (Correct answer)
- 35°F (2°C)
Correct answer: 40°F (4°C)
The FDA Food Code requires dairy-based fillings to be held at 40°F (4°C) or below to stay within the safe cold-holding zone.
Question 3: How long can a baked fruit pie safely sit at room temperature before it must be discarded or refrigerated?
- 1 day
- 2 days (Correct answer)
- 4 days
- 6 hours
Correct answer: 2 days
A baked fruit pie can remain at room temperature for up to 2 days; beyond that, sugar and acid content are insufficient to prevent spoilage.
Question 4: What wrapping method best prevents freezer burn on frozen pies?
- Single layer of plastic wrap
- Aluminum foil only
- Double wrap with plastic wrap followed by aluminum foil (Correct answer)
- Wax paper and a loose lid
Correct answer: Double wrap with plastic wrap followed by aluminum foil
A double wrap—plastic wrap pressed against the surface followed by foil—creates an effective moisture and vapor barrier that prevents freezer burn.
Question 5: Why should a freshly baked pie be fully cooled before refrigerating?
- To prevent the crust from becoming tough
- To avoid raising the refrigerator temperature and forming condensation inside (Correct answer)
- To allow the filling to fully set under gravity
- To reduce the electricity consumption of the refrigerator
Correct answer: To avoid raising the refrigerator temperature and forming condensation inside
Placing a hot pie in the refrigerator raises its internal temperature, which can bring other foods into the danger zone and cause condensation that softens the crust.
Question 6: What is the primary cause of a soggy bottom crust in a stored fruit pie?
- Excess fat in the dough formula
- Moisture migration from the filling into the crust over time (Correct answer)
- Overbaking the crust during initial bake
- Using bleached flour instead of unbleached
Correct answer: Moisture migration from the filling into the crust over time
As a baked fruit pie sits, moisture continuously migrates from the high-water filling into the porous baked crust, causing it to soften and become soggy.
Question 7: How long can unbaked pie dough be safely stored in the refrigerator?
- 1 day
- 3 days
- 7 days
- 2–3 days (Correct answer)
Correct answer: 2–3 days
Unbaked pie dough kept tightly wrapped can be safely refrigerated for up to 2–3 days before the fat oxidizes and the dough loses its flakiness.
