The delicious frozen dairy products of today evolved from the flavored ices popular with the Romans in the 4th century B.C. The hand-crank freezer, patented in1846, led to the establishment of the first commercial ice cream plant in Baltimore in1851. Frozen yogurt was introduced in the late1960s, and has since enjoyed increased popularity.
VARIETIES
Ice Cream is made by stirring, while freezing, a pasteurized mix of one or more dairy ingredients— milk, concentrated fat-free milk, cream, condensed milk— sweetening agents, flavorings, stabilizers, emulsifiers and optional egg or egg yolk solids or other ingredients. Federal standards require ice cream to contain a minimum of 10% milk fat (about 7 grams (g) of fat per 1 /2cup serving) and 20% total milk solids by weight. Some premium ice creams contain 16% milk fat. Added flavoring must be identified on the label as naturally flavored (i.e., raspberry ice cream) or artificially flavored (i.e., raspberry-flavored ice cream or artificially flavored raspberry ice cream).
Sherbet contains 1 to 2% milk fat and 2 to 5% total milk solids. Water, flavoring (e.g., fruit, chocolate, spices), sweetener and stabilizers are added. Sherbet has more sugar than ice cream.
Frozen Yogurt is made by freezing a mixture of pasteurized milk, with or without other milk products, flavorings, seasonings, stabilizers, emulsifiers and lactic acid cultures. Because there are no specific standards for frozen yogurt, its ingredients and characteristics can vary. Frozen yogurt is pasteurized before freezing so it generally does not contain live, active cultures like many unfrozen yogurts. Nonfat, lowfat and full fat varieties of frozen yogurt are available. Frozen yogurt may be soft (as in cones or sundaes) or hard-frozen.
Frozen Custard French ice cream, French custard ice cream) is similar to ice cream but contains a higher content of egg yolk solids.
Reduced-Fat Ice Cream Lowfat Ice Cream, Light Ice Creamand Fat-Free Ice Cream all contain less fat per serving (1/2cup) than regular (full fat) ice cream. Reduced-fat ice cream contains at least 25% less fat than the original product. Lowfat ice cream contains 3 grams (g) or less of fat per serving. Light ice cream contains at least 50% less fat, and fat-free ice cream contains less than 0.5 gram (g) of fat per serving.sundaes) or hard-frozen.
