Where these two actually differ

  • We flag Oxidative degradation and rancidity and Thermal decomposition and acrolein formation at very high heat on the Canola Oil and not on the Crisbee.
  • We flag Oil rancidity and off-gassing and Allergen risk from plant oils on the Crisbee and not on the Canola Oil.
  • The Canola Oil is Refined canola oil, liquid where the Crisbee is Organic waxes and oils blend, which is most of the difference in these two grades.

Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
