Jolly Rancher is a brand of sweet, somewhat tangy or sour/sweet hard candy, gummies, fruit chews, jelly beans, lollipops, gelatin desserts, gum, and sodas. It is currently owned by The Hershey Company. The product was originally produced by the Jolly Rancher Company, founded in 1949 by Bill Harmsen of Golden, Colorado. The Jolly Rancher Company made ice cream, chocolate and candy sold at several "Ranch Maid Ice Cream" stores in the Denver area. The name was meant to suggest a hospitable, western company.
Jolly Rancher candies original flavors were watermelon, grape, apple, and Fire Stix, later were cherry, orange tangerine, lemon, peach, and sour apple. Later, blue raspberry replaced lemon. In 2013, lemon was reintroduced in an all-lemon bag. Current flavors include cherry, blue raspberry, grape, green apple and watermelon. There are also sour, berry, cinnamon, and smoothie varieties. In 2015, Jolly Rancher offered a "Fruity Bash" variety bag which includes strawberry, mountain berry, lemon, orange, and pineapple. They also offer a "red" bag, with flavors such as strawberry and fruit punch, along with other "red" flavors. As of 2012, the peach flavor and wild berry flavors were discontinued by The Hershey Company.
Hard candy is an amorphous solid made from a solution of sugar, water, coloring and flavorings. It is characterized by the glass transition temperature, below which the amorphous material behaves like a rigid solid. Above the temperature, the solid is liquid-like and rubbery. The viscosity of the sugar solution near the glass transition temperature is described by the William-Landel-Ferry equation:
ln[ɳ(T)/ɳg] = -C1(T-Tg)/[C2 + (T-Tg)]
- ɳ(T) is the viscosity at temperature T
- ɳg is viscosity at the glass transition Tg
- C1 and C2 are constants
