What is Frozen Yogurt?

Frozen yogurt has been decried by many to be a pale imitation of the much beloved ice cream. Others laud its dietary virtues and find its characteristics to be the equal of ice cream, or even better. Either way, frozen yogurt---also referred to as "froyo" and "frogurt"---has developed a following, with several chains and retailers opening dealing exclusively in the dessert.

Background

Ice cream has always been a popular treat. As it is not the most healthy confection, however, attempts were made to produce something similar that was just as delightful but slightly less demanding on the waistline. With this in mind, frozen yogurt was invented. Its first introduction to the market in the 1970s, however, met with disastrous results. The taste and texture were too similar to yogurt to allow anyone to fool themselves into believing that this was a truly decadent dessert. The recipe and process were perfected by the 1980s and soon took the nation---and world---by storm. Frozen yogurts, in a variety of flavors, are sold alongside ice cream in grocery stores and ice cream parlors, and can be served much in the same way.

Ingredients

Frozen yogurt primarily contains milk fat, yogurt culture, sugar, stabilizers (for consistency) and emulsifiers (for blending). Flavorings---typically fruits and spices---are also included.

Process

Frozen yogurt is made much in the same way as ice cream. When it comes to large-scale manufacturing, the first step is to mix the ingredients. The mix is then pasteurized to kill off any bacteria and for preservation. Then, it is homogenized to produce a smoother texture. The mix is then given the yogurt culture, set, cooled and aged. Once these steps are complete, the flavorings can be added. The result can then be frozen, packaged and shipped.

Benefits

Frozen yogurt, in comparison with traditional ice cream, is comparatively low in calories and fat. This makes it a popular choice with dieters and the health-conscious. In addition, frozen yogurt can be a good source of calcium and protein and has some of the digestive benefits of yogurt. However, frozen yogurt is not an alternative to yogurt and should not be considered a "health food."

Popularity

Around 100 million gallons of frozen yogurt are sold every year. The treat has also occasioned its own national day, February 6, though another one is usually scheduled during the warmer months.
