sugar*
Sugar provides readily available carbohydrate energy (4 calories per gram) but lacks vitamins, minerals, and fiber; consumption should be moderated to maintain balanced nutrition. Less-refined varieties such as muscovado and coconut sugar retain trace minerals including potassium, magnesium, and iron, though in negligible quantities compared to whole foods.
About
Sugar refers to simple carbohydrates, primarily sucrose, derived from sugar cane (Saccharum officinarum) or sugar beets (Beta vulgaris), though the term encompasses other monosaccharides and disaccharides like glucose, fructose, and lactose. Sucrose, the most commonly refined and consumed form, is a disaccharide composed of glucose and fructose molecules bonded together. White granulated sugar is produced through a multi-step extraction and crystallization process: juice is extracted from the source plant, clarified, concentrated through evaporation, crystallized, and centrifuged to separate crystals from molasses. The crystals are then dried and refined. Other varieties include brown sugar (white sugar with molasses reintroduced), muscovado (moist, less-refined cane sugar), demerara, turbinado, and coconut sugar, each with distinct crystalline structures and residual molasses content.
Culinary Uses
Sugar functions as both a sweetening agent and a crucial structural component in baking, where it affects moisture retention, browning (through caramelization), and texture. In baked goods, sugar tenderizes by interfering with gluten development and promotes spreading in cookies through hygroscopicity. Beyond sweetening beverages and desserts, sugar caramelizes at high temperatures to create complex flavors and amber color in sauces, glazes, and confections. It is essential in preserving fruits through osmotic pressure, fermentation (supplying fuel for yeast), and stabilizing egg white foams in meringues. Sugar also balances acidity in sauces and dressings, and features in savory applications including Asian stir-fries, marinades, and cured meats.
