Zucker

Zucker is the German word for sugar and also a common surname. As a noun, Zucker denotes the sweet, soluble carbohydrate used as a food additive and flavoring. In most contexts it refers to sugar in general, typically the disaccharide sucrose, but the term can also apply to other refined sugars or sweeteners when distinguished by context. Sugar occurs naturally in many plants and is commercially refined from sources such as sugar cane and sugar beet. White sugar is highly refined and crystalline; brown sugar contains molasses; powdered sugar is finely ground.

In nutrition, sugar provides energy, delivering about 4 kilocalories per gram. Dietary guidelines generally advise limiting added sugars due to associations with dental caries and metabolic risk when consumed in excess. Sugar quality and processing influence flavor, texture, and shelf life in food products.

Historically, cane sugar has been produced in tropical regions for centuries, while sugar beet became an important domestic source in temperate climates, especially in Europe, starting in the 19th century. The development of beet sugar supported domestic industries and reduced reliance on imports. Refining processes separate sucrose from other carbohydrates, yielding forms such as granulated, brown, and liquid sugars used in cooking and baking.

As a surname, Zucker is of German origin and is borne by individuals in various fields. Notable people include the American film director Jerry Zucker. The name appears in German-speaking and Jewish communities and is found in multiple countries.
