American Ice Cream

American ice cream

　　American ice cream typically contains about 12% milk fat, 11% non-fat milk solids, 15% sugar, 0.2% stabilizers, 0.2% emulsifiers, and a small amount of vanilla flavoring. The total solids content is 38.4%, with the remainder being water. To this mixture, ingredients such as nuts, fruits, chocolate, eggs, and other flavoring substances can also be added. When making more premium ice cream, the formula is adjusted accordingly—its milk fat content can reach up to 18%, whereas regular commercial ice cream contains only 10%, ice milk products contain 4%, and juice-flavored popsicles generally have less than 2%, with juice bars usually containing no fat at all.

　　Milk fat is the most expensive ingredient in ice cream, so the higher the fat content, the higher the production cost. Currently, both federal and state governments have regulations regarding the composition of frozen desserts, most of which are based on milk fat and total milk solids content. This means that according to standards, regular ice cream can have less than 10% milk fat and 20% total milk solids; nut, fruit, and chocolate ice creams can have less than 8% milk fat and 16% total milk solids. Other ingredients are also permitted. Products that fall below these standards cannot be called ice cream.

　　During the mixing process of ice cream ingredients, many uniform air bubbles are incorporated, increasing the volume. After being cooled in a brine solution, fine ice crystals form. The incorporation of air is essential—it’s a critical production factor that prevents the ice cream from freezing too hard and ensures a soft, smooth texture. While maintaining the desired mouthfeel, the overrun (expansion rate) of ice cream is generally controlled between 70–100%. Too high an overrun results in an overly airy texture, similar to eating cotton candy. In other words, one liter of ice cream mix can produce approximately two liters of finished ice cream.
