Screening model notes
How Nutri-Score, NOVA, and list length read this record
Within the four-tier shelf-label framework this site publishes, the composite for this product falls in the highest band. That band is defined by a threshold on the derived score alone: it is where labels land once components carrying caution-or-worse registry ratings contribute little or nothing to the deduction. The band is a summary of what the screened registries return for the components that were parsed, so it inherits their coverage gaps — a component absent from both registries neither raises nor lowers the figure. The threshold and the weighting behind it are set out on the methodology page.
Nutri-Score assigned its lowest band to this label. The algorithm reserves that grade for nutrition panels where the values it penalises sit well above the components it credits. The two systems on this page measure genuinely different things: a product can hold this grade while carrying no additive flagged by the registries screened below, and a product graded well can carry several. Neither reading substitutes for the other, and the per-component table is where the additive picture is set out.
The declared list parsed into a small number of components. On a short list the registry screen covers close to everything the packaging declares, and any single matched component accounts for a correspondingly large share of the composite. Short lists also leave less room for parsing error, since there are fewer separators and qualifiers for the extraction to resolve.

How It Compares to Its Category

Mayonnaise scores 4.9 points above that category average (100/100 vs. 95.1/100), so it is roughly typical for shoppers screening within that category specifically, rather than against the product catalog as a whole.

Ingredient-list length is a descriptive property of the label, not a safety rating. A longer list is not automatically worse and a shorter one is not automatically better; the count is shown so the label can be placed against a comparable population. The comparison here runs against the 1,052 Null products we publish with a parsed label, not against the whole catalogue, because list length varies far more between categories than within one.
