Currently in California there are four ice cream products that are defined by the state legislature--ice cream, ice milk, light dairy dessert and frozen yogurt.
Fat content is the primary difference between these frozen treats, said Bob Boynton, executive director of the Dairy Institute of California in Sacramento.
Premium and super premium are names given by the ice cream industry to describe quality, Boynton said. The terms reflect the density and the increased levels of milk fat of a product and perhaps expensive or exotic flavoring ingredients, but there is no legal basis to any of the terms, he said.
"Generally speaking, the quality of the product serves as a fairly effective regulator," Boynton said. "If there is too much air in a product, it doesn't taste good, it doesn't have good mouth feel. But clearly the density of the product is related to the calories."
