"A synthetic sulfite preservative and antioxidant."
Sulfite preservatives like this one are known to destroy thiamine (vitamin B1) in the food they're added to — a genuine nutritional cost, not just a safety question — and they're also recognized human allergens capable of triggering asthma-like reactions in sensitive individuals. Safer, non-thiamine-destroying preservatives exist and are widely used instead. Score: 2/10.
A meaningful red flag: an unnamed source, heavy processing into a by-product or digest form, or documented regulatory scrutiny in at least one country. -4 pts deducted.
