CDM Quality Control & Food Safety Standards 4 — Questions and Answers
Question 1: What is the maximum time a doughnut made with a custard or cream filling can safely remain at room temperature (above 41°F)?
- 30 minutes
- 1 hour
- 2 hours (Correct answer)
- 4 hours
Correct answer: 2 hours
The FDA Food Code's 2-hour rule limits how long temperature-controlled-for-safety (TCS) foods like cream-filled doughnuts can remain in the danger zone.
Question 2: Oil quality in a doughnut fryer is BEST monitored using:
- Color comparison against a fresh oil sample only
- A combination of FFA (free fatty acid) testing and a colorimetric test strip (Correct answer)
- Taste testing by trained staff every hour
- Daily visual inspection for darkening
Correct answer: A combination of FFA (free fatty acid) testing and a colorimetric test strip
FFA tests measure oil degradation chemically, while colorimetric strips detect total polar compounds, providing objective oil quality data.
Question 3: Which document provides written proof that a supplier meets food safety standards acceptable for doughnut ingredient purchasing?
- Certificate of Analysis (COA) (Correct answer)
- Material Safety Data Sheet (MSDS)
- Standard Operating Procedure (SOP)
- Corrective Action Report (CAR)
Correct answer: Certificate of Analysis (COA)
A Certificate of Analysis from a supplier documents lab testing results confirming that an ingredient meets specified quality and safety standards.
Question 4: What is the PRIMARY food safety risk associated with using recycled frying oil that has exceeded its quality threshold?
- Increased gluten development in the dough
- Formation of harmful polar compounds and acrylamide (Correct answer)
- Faster yeast activity in yeast-raised doughnuts
- Reduced absorption of sugar from glazes
Correct answer: Formation of harmful polar compounds and acrylamide
Degraded frying oil produces elevated levels of polar compounds and acrylamide, both of which are linked to health risks and regulatory violations.
Question 5: A batch of cake doughnuts has excessive grease absorption. The MOST effective corrective action is to:
- Increase the frying temperature to reduce contact time
- Lower the baking powder percentage in the formula
- Reduce dough hydration and check oil temperature (Correct answer)
- Switch from shortening to vegetable oil
Correct answer: Reduce dough hydration and check oil temperature
Excess grease absorption in cake doughnuts is often caused by too much moisture in the batter or oil that is too cool, both of which slow crust formation.
Question 6: Under FDA FSMA Preventive Controls rules, who must develop and oversee a food safety plan for a doughnut manufacturing facility?
- A state-licensed food inspector
- A Preventive Controls Qualified Individual (PCQI) (Correct answer)
- Any manager on duty during production
- A USDA-certified food scientist
Correct answer: A Preventive Controls Qualified Individual (PCQI)
FSMA requires that a PCQI — someone who has completed FDA-recognized training — develop, validate, and oversee the facility's food safety plan.
Question 7: When performing a shelf-life study on packaged doughnuts, which factor is MOST critical to monitor for yeast-raised varieties?
- Color change of the glaze over time
- Mold growth and staling rate (Correct answer)
- Fat content migration to the packaging
- pH increase above 7.0
Correct answer: Mold growth and staling rate
Mold growth and staling (firming of crumb structure) are the primary spoilage mechanisms that limit the shelf life of yeast-raised doughnuts.
