Hey everyone, if you’ve ever flipped through a skincare label, stared at the back of a snack bag, or sniffled at a flower shop’s display, odds are you’ve run into flavors and fragrances (F&F) – my actual day job, for full transparency. I run a small F&F supplier (I know, not some giant corporate lab, just a crew of folks who geek out over smells and tastes) and get asked this nonstop: “Can flavors and fragrances be made from natural sources only?” Flavors & Fragrances
Short answer? It’s way more complicated than it sounds, and the line between “natural” and “not” is way fuzzier than most people think. Let’s break this down like I chat with my team over coffee, no stuffy jargon, promise.
First, let’s define what “natural” even means here, because every time I work with a new client on this exact topic, we have to hash this out. The FDA’s definition (which we stick to, since we work with US and EU clients mostly) says a natural flavor is a substance derived from plant, animal, microbial, or mineral sources via physical, enzymatic, or microbial processes. So like, if you extract vanilla beans with alcohol? That’s natural. If you ferment sugar cane to get vanilla? Still counts as natural. But if you take a lab-made chemical that’s identical to the vanilla compound found in beans? That’s artificial, even if it’s chemically the same. Got it? Good.
Now, why would anyone want all-natural F&F in the first place? That’s the big driver these days – consumer demand for cleaner labels, “better for you” ingredients, that whole vibe. I had a major craft soda client hit me up last year begging for 100% natural strawberry flavor, and that’s what set me deep into this rabbit hole. Turns out, making a consistent strawberry flavor only from natural stuff is way harder than just dumping a lab-made compound in.
Here’s the problem with going 100% natural: yield and consistency. Let’s take one of the most common fragrance compounds, linalool – it’s that soft, flowery, hint-of-lavender smell that’s in everything from laundry detergent to perfume. If I wanted to make linalool only from natural sources, I’d have to extract it from either lavender or coriander. Wait, how much linalool is in coriander seeds? About 0.1 to 0.2% by weight. So to get 1 kilo of pure natural linalool, I’d need 500 to 1000 kilos of coriander seeds. That’s like, 1,100 to 2,200 pounds of seeds. Coriander isn’t cheap either – especially not if you’re buying food-grade, no pesticides, which we have to do for our clients that sell to kids or organic stores.
Then there’s consistency. Natural stuff changes with every harvest. One year, if lavender got too much rain, it has less linalool. If a strawberry crop gets hit by heat, the level of that sweet, ripe compound called furaneol drops, and suddenly your flavor tastes like a sour, unripe berry instead of the plump, juicy stuff people know. My soda client tried making their natural strawberry flavor a while back and had to pull three batches when the harvest from their Mexican strawberry farm fluctuated – one batch tasted like toothpaste, another like wet grass. That’s not good for a product that’s supposed to be reliable.
Don’t get me wrong, we can make a lot more natural F&F these days than we could 20 years ago. Thanks to biotech (and no, I’m not talking about weird GMO franken-anything), we can use yeast or bacteria to make natural compounds that are identical to what’s in plants, without taking up acres of farmland. Wait, let’s clarify that: this is called “natural identical” but wait, no – under the FDA definition, if you make it via microbial fermentation of natural sugars, it’s considered natural. Oh right! The yeast eats glucose (which comes from corn or sugar cane, totally natural) and spits out that exact linalool compound. That way, you get 100% natural linalool, way more consistent, and way less impact on the planet than growing all those coriander seeds.
But even with that, there are some flavors you just can’t get 100% natural, full stop. Let’s take blueberry flavor, for example. Fresh blueberries have over 100 volatile compounds that add up to that iconic taste. Natural blueberry flavor would usually use a mix of extracts from actual blueberries, but even then, it’s missing a few key compounds that make that flavor pop. Wait, but here’s the catch: some of those missing compounds aren’t even present in blueberries in high enough amounts to extract practically. They’re byproducts of how blueberries ripen – a tiny trace that’s part of the overall flavor profile, but too rare to get from actual fruit. So you either have to make them via those microbial processes (counted as natural) or use synthetic versions (artificial).
And it’s not just about taste or smell – it’s about safety. Wait, I know what you’re thinking: “natural is safer, right?” Not always. Let’s take safrole, which is in sassafras root. It’s natural, but it’s toxic in high doses, and banned from food use by the FDA. If I tried to make a root beer flavor only from natural sassafras, I’d have a product that’s unsafe. So I have to either modify it to remove the toxic part (still natural, via enzymatic processing) or use a synthetic version that’s identical but non-toxic.
Another big one is cost. For a small F&F supplier like me, pricing is everything. If you want all-natural vanilla extract for a cake mix? That’s expensive – like, $50 a kilo vs. lab-made vanillin that’s $5 a kilo. Most consumers won’t pay a $2 premium for a product just because the flavor is natural. So it’s a balance between what clients want, what’s safe, what’s consistent, and what’s affordable.
Wait, let’s talk about what clients actually ask for, because that’s my whole business. I had a skincare client come to me last month begging for 100% natural rose fragrance for their clean beauty line. They wanted to put “100% natural rose fragrance” on their label, no exceptions. So I couldn’t use that fermented linalool – wait no, actually linalool is part of rose scent, but I needed the full profile. So we sourced absolute rose oil from a small organic farm in Bulgaria, mixed it with other natural compounds that we could get from natural sources, like geraniol (another rose compound from geraniums) and citronellol. The end product is 100% natural, smells like fresh-cut roses, and is safe for skincare. But the cost? It’s three times higher than a regular rose fragrance, so their product is priced accordingly. That works for their niche, but if they tried to sell it at Target for $5 a bottle, it wouldn’t make sense.
I also need to address the elephant in the room: greenwashing. So many brands slap “natural” on their labels when they’re 90% synthetic, with just a splash of natural extract. I hate that. That’s why my team is super transparent with clients. If we make a flavor that’s mostly natural with a small amount of lab-made compounds to keep it consistent, we tell them. We don’t lie and say it’s 100% natural if it’s not, because trust is everything in this industry.
Now, is there a future for 100% natural F&F? Yeah, but it’s not going to be every single product. We’re already seeing more biotech processes that can make more compounds naturally, without farming tons of crops. I’m working with a lab that’s figuring out how to make natural coffee flavor without using actual coffee beans – that would cut down on deforestation from coffee farming, which is a big win. But there will always be some gaps where synthetic compounds make sense, either because they’re safer, cheaper, or just can’t be replicated natural.
Wait, let’s get back to the original question: Can flavors and fragrances be made from natural sources only? The short answer for most products today is “no, not really,” but for niche, higher-end products, absolutely. But it requires a lot of work, a lot of cost, and a lot of flexibility on what “natural” actually means. It’s not as simple as “all natural = good, not natural = bad” – that’s a myth that I see all over social media, and it frustrates me because it’s way more nuanced than that.
If you’re a brand owner or procurement manager looking to develop a new flavor or fragrance line – whether it’s food, skincare, home goods, anything – I’m here to help. I know how to balance natural sourcing, consistency, safety, and cost, and I’ll never push a product that doesn’t make sense for your brand or your customers. Drop me a line to chat through your project, no strings attached, just a conversation about what works best for you.
