Study Notes
Thermometers Overview
- Infrared thermometers measure surface temperatures, providing quick readings without contact.
- Accuracy for food thermometers must be within ±2°F (±1°C).
- Using color-coded cutting boards helps prevent cross-contamination in food preparation.
Monitoring Temperature and Time
- Time-Temperature indicators track both time and temperature to prevent food spoilage during shipment and storage.
- Food must be discarded if it stays in the temperature danger zone (41°F to 135°F or 5°C to 57°C) for more than 4 hours.
Preventing Foodborne Illness
- Limiting food removal from coolers while prepping prevents time-temperature abuse, reducing risks of foodborne illness.
- Most foodborne pathogens proliferate rapidly between 70°F and 125°F (21°C and 52°C).
Thermometer Types and Their Uses
- For chicken breast temperature checks, use a penetration probe to ensure accurate readings.
- A bimetallic stemmed thermometer should be inserted to the dimple for an accurate temperature reading.
- Cutting boards used for raw chicken must be washed, rinsed, and sanitized before prepping other foods.
Best Thermometers for Specific Foods
- Bimetallic stemmed thermometers and thermocouples with penetration probes are ideal for measuring internal temperatures of fish and roasts.
- Thermocouples with immersion probes are best for testing the internal temperature of frying oil.
- Surface probes or infrared thermometers are recommended for checking surface temperatures of griddles.
Thermometers for Air and Liquid Measurement
- Thermocouples with air probes efficiently measure air temperature inside coolers.
- Immersion probes are suited for measuring the temperature of liquids such as soups, sauces, and frying oil.
- Surface probes are employed to verify temperatures of flat cooking equipment like griddles.
- Air probes are used for checking the temperature inside coolers and ovens, ensuring food safety during storage and cooking.
