The verdict
udon by Nasoya scores 95/100 in PlainFoodSafe's ingredient screening. We compared its 43 labeled ingredients with FDA SAFFA regulatory records and CSPI Chemical Cuisine ratings; 1 ingredient is flagged for caution. The source parser split this into a very long 43-component record, beginning with Wheat Flour, Water, Tapioca Starch. That density can include amounts and label fragments, so verify the physical label before relying on ingredient order or completeness. This is not a recall, allergy, medical, or dietary-safety determination.

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 settled on its middle grade here, the band the algorithm produces when the penalty and credit sides of its nutrient ledger come out close to balanced. A mid-scale grade is a statement about the panel as a whole rather than about any single nutrient, and products arrive at it by very different routes: a moderate profile across every term, or high marks on some offset by heavy penalties on others. The grade is computed separately from the ingredient screen below and the two are not comparable measures.
The declared list is among the longer ones in this catalogue. A component set this wide means the screen returns many individual ratings, and the composite accumulates a large number of small contributions instead of turning on a handful of entries. At this length the per-component table below is substantially more informative than the single figure, because the figure compresses a great deal of variation into one number.

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 63,434 Plant-based foods and beverages products we publish with a parsed label, not against the whole catalogue, because list length varies far more between categories than within one.
