Terpenes’ Role in Creating Flavors and Scents

Terpenes are naturally occurring chemical compounds that produce the distinct flavors and scents of all flowers, plants, fruits, and trees. Some terpenes attract pollinators, which is essential for plan reproduction and maintaining natural diversity. Meanwhile, others boost the immune system of plants, heal them from damage, and protect them from harsh weather and predators like insects or foraging animals. 

Existing studies have shown that terpenes also produce flavors and scents with positive effects on humans. For instance, limonene creates the sweet and zesty flavors of citrus fruits like orange, lime, and lemon, serving as an additive in foods and beverages, cosmetics, cleaning products, and insect repellants. It’s also used in aromatic oils that induce calming effects.

Terpenes are sometimes interchanged with a term called terpenoids. The reality is that they’re different. Terpenes are a live plant’s natural compounds, while terpenoids result from oxidized terpenes. The former is also more volatile than the latter.
