NEW YORK -- Pizza Hut says it will remove more artificial ingredients from its pizza pies in the next year.
The company already killed artificial flavors and colors from some of its pizzas last year.
Pizza Hut says the preservatives BHA and BHT will be removed from all its meat by next month. 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.
