Excerpts from the report: The marketing of frozen dessert made with fats other than milk fat is carried on in several parts of the United States. Statistics of the marketing of this product (commonly known as mellorine) show such wide variation that one obviously must make a close study of individual situations to gain an understanding of the factors involved. The product is essentially local--ordinarily at least to the State in which it is made--in both manufacture and sale. What is important in marketing mellorine in one area is sometimes insignificant in another. In only 12 States do the legal standards for the composition of frozen desserts permit the use of fats other than milk fat, and there are differences among the laws of these 12 States.
