corn syrup
Corn syrup is the label's busiest red flag — a sugars-list term, an added-sugar flag in the top 10, and a corn entry for the splitting rule, all at once.
Also appears on labels as: corn syrup solids · dried corn syrup · glucose syrup
What it is
Glucose syrup hydrolyzed from corn starch, sold liquid or as dried solids. Functionally it's sugar with better binding — the humectant-sweetener that keeps semi-moist foods and treats pliable.
Why it's in pet food
Texture, shelf-stable moisture, and palatability at commodity price. It marks a product's era and positioning: corn syrup high on a list is a formulation from the semi-moist school, not the fresh-ingredient one.
How Bowlmark scores it
Scores are deterministic math over the printed label — the rules below apply to every product identically, and nothing estimates or fills in a blank.
Three engine touchpoints. It's a sugars term (two distinct sugars anywhere → −8); it's an added-sugar flag name (top 10 → −20 warn); and its wording counts toward the CORN splitting base, so corn + corn gluten meal + corn syrup in the top 8 completes the ≥3 fractionation pattern for that −12. One ingredient can participate in all three — the engine's rules see different sins in the same syrup.

Is corn syrup bad in dog food?
It is functionally sugar with better binding, and the engine treats it as the label's busiest red flag — a sugars-list term, an added-sugar flag when it appears in the top 10, and a corn entry for the splitting rule, all at once.
How does Bowlmark score corn syrup?
Three engine touchpoints. It is a sugars term (two distinct sugars anywhere → −8); it is an added-sugar flag name (top 10 → −20, shown as a warning); and its wording counts toward the corn splitting base, so corn + corn gluten meal + corn syrup in the top 8 completes the ≥3 fractionation pattern for that −12. One ingredient can participate in all three.
