Pizza Hut says it will remove more artificial ingredients from its pizza pies in the coming year.
The company, which scrapped artificial flavors and colors from some of its pies last year, will remove the preservatives BHA and BHT from all its meat by next month, according to Pizza Hut.
Artificial preservatives in cheese will be cut by next year. Chicken used as pizza topping will be free of human antibiotics by March.
Some of the world's biggest restaurant chains have been tinkering with their recipes to appeal to people who are paying more attention to ingredient labels. McDonald's Corp., for example, is testing Chicken McNuggets without artificial preservatives.
Pizza Hut, owned by Louisville, Kentucky-based Yum Brands Inc., has about 16,000 restaurants.
