Why this grade

Where these two actually differ

  • We flag Oil rancidity and off-gassing and Allergen risk from plant oils on the Crisbee and not on the Peanut Oil.
  • We flag Rancidity and oxidative degradation, Aflatoxin contamination (Aspergillus flavus) and Pesticide residues on the Peanut Oil and not on the Crisbee.
  • The Crisbee is Organic waxes and oils blend where the Peanut Oil is 100% peanut oil, liquid cooking oil, 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 →
