Study Notes

Flow of Food

  • Represents the journey food takes from receipt to service.

Time-Temperature Control

  • Refers to temperature maintenance between 41ºF and 135ºF, known as the temperature danger zone.

Cross-Contamination

  • Occurs when bacteria or pathogens transfer from one food item to another, posing a safety risk.

Avoiding Time-Temperature Abuse

  • Essential practices include:
    • Monitoring food temperatures
    • Using accurate thermometers
    • Maintaining records
    • Implements procedures to minimize time in the danger zone
    • Taking corrective actions when necessary

Immersion Probes

  • Designed for measuring temperatures of liquids, such as soups, sauces, and frying oils.

Surface Probes

  • Used to assess temperatures of flat cooking surfaces like griddles.

Penetration Probes

  • Ideal for checking the internal temperatures of food, especially thin items like hamburger patties and fish fillets.

Infrared (Laser) Thermometers

  • Provide accurate temperature readings for food and equipment surfaces.
  • Minimize cross-contamination and damage as they do not contact food; unsuitable for measuring air or internal temperatures.

Cleaning and Sanitizing Thermometers

  • Must be washed, rinsed, sanitized, and air-dried before and after each use to ensure safety.

Checking Temperatures

  • Insert thermometers into the thickest part of the food product for accurate readings.

Calibration

  • Refers to adjusting equipment to ensure it functions effectively and accurately.

Accuracy

  • The term describes how closely a measurement corresponds to the actual value.

Glass Thermometers

  • Consist of a hollow glass stem and bulb filled with mercury or alcohol and can be hazardous if broken.
  • Must be used within a shatterproof casing to prevent contamination.

Air Temperature in Food Storage

  • Should be maintained within +/-3ºF or +/-1.5ºC for proper safety compliance.

Food Temperature in Food Storage

  • Must be maintained within +/-2ºF or +/-1ºC for optimal safety and quality assurance.
