Oil roasted
Match salt state and oil-roasted product.
Raw or boiled
Use the raw or boiled-peanut record rather than roasted values.

QUALITY & SAFETY
How to choose, store and prepare it
Store
Keep peanuts sealed away from heat, light and moisture.
After opening or cutting
Use a clean, dry utensil for shared containers.
Prepare
Follow package allergen and cross-contact guidance.
Safety boundary
Discard mouldy or unmistakably rancid nuts; the nutrient record does not establish storage duration.
PHOTO LOGGING
How to log dry-roasted peanuts more accurately
A food photo can suggest the ingredient, but it cannot always reveal exact weight, hidden oil or preparation details. These checks turn an image guess into a better estimate.
