甜味是一种基本的味觉。在全球众多文化中，甜味都象征着美好的感觉。

许多化合物是甜的，在生化物质中简单的碳水化合物都有些甜味，蔗糖是典型的甜味物质，而果糖更甜。许多植物会产生葡萄糖苷（配糖体，glycoside）比糖要甜很多。

Sweetness is one of the five basic tastes and is universally regarded as a pleasurable experience, except perhaps in excess. Foods rich in simple carbohydrates such as sugar are those most commonly associated with sweetness, although there are other natural and artificial compounds that are sweet at much lower concentrations, allowing their use as non-caloric sugar substitutes. Examples of foods that may be used as non-sugar sweet substitutes include saccharin, aspartame, acesulfame potassium, sucralose, xylitol, erythritol, and stevia. Other compounds, such as miraculin, may alter pe****tion of sweetness itself.
