Candy

Candy, often called sugar confectionery, is a sweet food where sugar is the primary ingredient. This category includes many varieties, such as chocolate, chewing gum, and hard sugar candies. While some foods like cakes are shared among many, candies are usually made in small, individual pieces. People typically eat them casually as a snack between meals rather than as a formal dessert. Because culture shapes how we eat, what one group calls candy, another might call a dessert.

The process of making candy relies on precise chemistry and temperature control. It begins by dissolving sugar in water or milk to create a syrup. As the syrup boils, water evaporates and the sugar concentration increases. This change raises the boiling point of the liquid, creating what are known as sugar stages. Higher temperatures and concentrations produce hard, brittle candies. Lower temperatures result in softer textures. If the syrup reaches very high temperatures, the sucrose molecules break down into an amber substance called caramel.

Confectioners classify sugar candies in several distinct ways. One method is by their microscopic crystal structure. Noncrystalline candies are homogeneous and can be chewy or hard, such as toffees and nougats. Crystalline candies contain small crystals that create a creamy texture, like fudge or fondant. Another classification is based on the cooking method. Hard-boiled candies use a vacuum cooking process. Open-fire candies, like taffy, are cooked in kettles and then pulled. Pan work candies involve coating items like nuts in revolving copper kettles.

The history of candy stretches back to ancient times and different ingredients. Before sugar was widely available, people used honey to coat fruits and flowers for preservation. In ancient India, people boiled sugarcane juice to create sugar pieces called khanda. Between the 6th and 4th centuries BCE, the Persians and Greeks learned about these "honey reeds" and spread sugarcane agriculture. In the Middle Ages, candy was a luxury for the wealthy. It was often used as a medicinal aid to help with digestion or to soothe sore throats.

The Industrial Revolution in the 1830s transformed the candy industry into a mass market. Technological advances made sugar more available, allowing the working class and children to enjoy sweets. Penny candy became a major phenomenon, representing the first goods children often bought with their own money. New inventions like the 1847 candy press allowed for many shapes to be made at once. In 1851, the revolving steam pan helped boil sugar more evenly. This prevented burning and meant only one or two people were needed to run a business.

As production grew, the industry faced serious safety challenges regarding additives. In the 19th century, some manufacturers used hazardous substances to create bright colors. For example, they used chromium(III) oxide for green and arsenic trioxide for white. A satirical 1885 cartoon in *Puck* warned of these dangers by linking candy to doctors and gravediggers. Public pressure and research eventually led to the 1906 Pure Food and Drug Act. This was the first federal law in the United States to regulate food and drugs, including candy.

Modern candy relies heavily on specialized packaging to ensure safety and quality. Packaging preserves aroma and flavor while making shipping easier. Materials like wax paper seal against moisture, while cellophane is used for its transparency and grease resistance. Aluminum foil is used for chocolate bars because it is lightweight and prevents water vapor transfer. The history of packaging changed significantly after a 1916 polio outbreak caused concern over germs in unwrapped candy. Today, factory-sealed packaging provides a recognizable brand name that helps consumers feel secure.
