Blue agave (Agave tequilana)
Because agave nectar dissolves quickly, it can be used as a sweetener for cold beverages such as cocktails, smoothies, and iced tea.

Agave nectar (more accurately called agave syrup) is a sweetener commercially produced from several species of agave, including Agave tequilana (blue agave) and Agave salmiana.[1][2] Agave syrup is sweeter than honey and tends to be less viscous. Most agave syrup comes from Mexico and South Africa.

Production[edit]

To produce agave syrup from the Agave americana and A. tequilana plants, the leaves are cut off the plant after it has been growing for seven to fourteen years. The juice is then extracted from the core of the agave, called the piña.[2] The juice is filtered, then heated to break the complex components (the polysaccharides) into simple sugars.[citation needed] The main polysaccharide is called inulin or fructosan and is mostly fructose. This filtered juice is then concentrated to a syrupy liquid, slightly thinner than honey. Its color varies from light- to dark-amber, depending on the degree of processing.

Agave salmiana is processed differently from Agave tequiliana. As the plant develops, it starts to grow a stalk called a quiote.[3] The stalk is cut off before it fully grows, creating a hole in the center of the plant that fills with a liquid called aguamiel. The liquid is collected daily. The liquid is then heated, breaking down its complex components into fructose and glucose and preventing it from fermenting into pulque.

An alternative method used to process the agave juice without heat is described in a United States patent for a process that uses enzymes derived from the mold Aspergillus niger to convert the inulin-rich extract into fructose.[4] Aspergillus niger, a fungus commonly used in industrial fermentations,[5] is "generally recognized as safe" (GRAS) by the U.S. Food and Drug Administration.[6]

Composition[edit]

Agave nectar consists primarily of fructose and glucose. One source gives 47% fructose and 16% glucose;[7] another gives 56% fructose and 20% glucose.[8] These differences probably reflect variation from one vendor of agave nectar to another.

Culinary use[edit]

Agave syrup is 1.4 to 1.6 times sweeter than sugar[9] and is often substituted for sugar or honey in recipes.[10] In cooking, it is commonly used as a vegan alternative to honey.[11] Agave syrup dissolves quickly and so it can be used as a sweetener for cold beverages such as iced tea. It is added to some breakfast cereals as a binding agent.[12]

Agave syrups are sold in light, amber, dark, and raw varieties. Light agave syrup has a mild, almost neutral flavor, and is therefore sometimes used in delicate-tasting dishes and beverages. Amber agave syrup has a medium-intensity caramel flavor and is therefore used in dishes and drinks with stronger flavors. Dark agave syrup has stronger caramel notes and imparts a distinct flavor to dishes, such as some desserts, poultry, meat, and seafood dishes. Both amber and dark agave syrups are sometimes used "straight out of the bottle" as a topping for pancakes, waffles, and French toast. The dark version is unfiltered and therefore contains a higher concentration of the agave plant's minerals.[13] Raw agave syrup also has a mild, neutral taste.[dubious ] It is produced at temperatures below 118 °F (48 °C) to protect the natural enzymes, so this variety could be considered an appropriate sweetener for raw foodists.[14]

Calories and glycemic index[edit]

Agave nectar has a high sweetness factor because it is composed of 70% to 90% fructose, giving an impact on blood sugar comparable to pure fructose, as measured by its glycemic index.[15] Although supplying more calories (60) compared to the same amount of table sugar (48), agave nectar has greater sweetness, indicating that its use per volume can be relatively lower, and it is not favorable as a low-calorie sweetener.[15]
