Freezing is not recommended for Dijon mustard as it can cause changes in texture (separation) and flavor upon thawing.

Signs of Spoilage

  • Off-odor (sour, yeasty, or unpleasant smell)
  • Visible mold growth
  • Significant discoloration (darkening or unusual color changes)
  • Excessive liquid separation that does not mix back in easily
  • Unusual texture (slimy or overly thick)

Room Temperature Safety

The 2-hour rule applies: Perishable foods should not be left at room temperature for more than 2 hours. If the ambient temperature is above 90°F (32°C), the limit is 1 hour.

The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C).

Opened Dijon mustard should not be left out at room temperature for extended periods. Promptly return to the refrigerator after use to prevent bacterial growth and maintain quality.
