How Biotechnology Creates Fragrance Ingredients
Biotechnology is reshaping the fragrance industry with two cutting-edge methods that offer a sustainable and consistent way to produce scent ingredients. These processes not only eliminate the uncertainties of traditional farming but also help preserve rare and endangered plant species. Let’s take a closer look at these innovative approaches and their impact on creating wellness-oriented fragrances.
Plant Cell Biotechnology
Instead of cultivating entire plants, plant cell biotechnology focuses on growing plant cells in controlled laboratory bioreactors. This technique is especially useful for producing rare and costly ingredients like orris butter, which traditionally requires years of aging. By isolating only the cells responsible for producing fragrance molecules, scientists can create these ingredients with minimal resource use.
This method also plays a crucial role in protecting biodiversity. Ingredients sourced from endangered plants - such as sandalwood, agarwood, and certain orchids - can now be synthesized without disrupting wild populations. As David Banks, Marketing Director at Bell Flavors & Fragrances, explains:
"I don’t have to cut down another tree - to me, that’s a win".
Additionally, this approach ensures safer formulations by producing purified fragrance molecules. By replicating natural extraction methods without relying on traditional agriculture, plant cell biotechnology offers a sustainable alternative.
Precision Fermentation
Precision fermentation takes a different route, employing microorganisms like yeast (Saccharomyces cerevisiae) and bacteria (Escherichia coli) as miniature factories for fragrance production. Scientists program these microbes using plant DNA, enabling them to convert sugars into complex scent molecules. Unlike chemical synthesis, which can result in mixtures with unwanted byproducts, fermentation delivers pure molecules with precise scent characteristics.
Several fragrance companies have already adopted this method to create innovative products. Firmenich, for instance, introduced Clearwood®, the first-ever biotech ingredient offering a sustainable patchouli profile. Givaudan has developed Ambrofix™ (woody/ambery notes) and Akigalawood® (spicy/woody) in its Switzerland pilot plant. In another example, Ginkgo Bioworks partnered with Robertet in 2015 to engineer yeast strains capable of producing peach, apricot, and coconut scents, marking a significant advancement in biotech fragrance production.
Unlike traditional farming, fermentation ensures consistent quality year-round. Sarah Reisinger, Senior Vice President for Research Operations at Firmenich, highlights the efficiency of biology in this process:
