Calories and nutrients

Not shown here. Open Food Facts records calories and nutrients per 100 g or per 100 ml without saying which, so a figure for all these packs together could mislead. The pack you buy prints its own, and that is the figure to log.

Every share is counted over the packs whose ingredient list Open Food Facts reads in full. A pack lists an allergen when Open Food Facts’ allergen field names it, or when one of its ingredients stands for it by the same two-of-three checks as the ingredient dictionary (tahini is sesame, a cheese is milk). A “may contain” line counts only for an allergen the pack does not list.
