NEW YORK (AP) — Kraft is removing artificial preservatives from its most popular Singles cheese product variety, in the latest sign that companies are tweaking recipes as food labels come under greater scrutiny.

The change affects the company’s Kraft Singles in the full-fat American and White American varieties, which Kraft says account for the majority of the brand’s sales. Sorbic acid is being replaced by natamycin, which Kraft says is a “natural mold inhibitor.”
