If you’ve wandered the aisles of a natural foods grocery lately, you’ve likely seen labels touting “plant-based preservatives” made from rosemary extract, “natural flavor boosters” from citrus peel oil, or even “antioxidant-rich leaf extracts” added to yogurt and protein bars. As a plant extracts supplier who’s spent 12 years working directly with food manufacturers, I get asked one question more than any other: Can plant extracts actually be used safely and effectively in food? The short answer is yes—but the longer answer is far more nuanced than the greenwashing headlines that often dominate food marketing. Let’s break down what really goes into using plant extracts in food, why they matter, and what it takes to make them work for both brands and consumers. Plant Extracts
First, let’s clear up a common misconception: not all plant extracts are created equal. When I first started in this industry, I saw a brand add a cheap, untested extract to a snack bar only to pull it months later—its off-flavor turned customers away, and the extract itself didn’t extend the product’s shelf life at all. The difference between a safe, effective extract and one that’s a waste of time and money lies in three things: sourcing, extraction method, and third-party safety testing. For example, our team works with small-scale organic farms in the Pacific Northwest for our rosemary extracts—we partner with farmers who test their soil for heavy metals, avoid synthetic pesticides, and harvest rosemary at peak oil content (right before it flowers, when the antioxidant levels are highest). Then we use a supercritical CO2 extraction method, which uses carbon dioxide under high pressure to pull the active compounds (like carnosic acid in rosemary) without leaving residual solvents. That’s miles better than cheap solvent extraction, which can leave harsh chemical smells or break down the beneficial compounds.
The biggest role plant extracts play in food is as a replacement for synthetic additives, and that’s where most of the confusion comes in. For decades, food manufacturers used synthetic preservatives like BHA and BHT to prevent fats from going rancid, or artificial flavors to boost taste. But as consumers have demanded cleaner labels, plant extracts have stepped in to fill that gap—when used correctly. Take a recent project I worked on with a plant-based meat brand. Their original product used a synthetic preservative to stop the plant fats from oxidizing, which would turn the patty sour after two weeks on the shelf. We worked with their R&D team to blend three extracts: rosemary, oregano, and green tea. We had to adjust the ratio, though—too much rosemary, and the patty tasted like a pesto; too little green tea, and it didn’t fight oxidation. After three months of testing, we landed on a 2:1:1 blend that extended the shelf life by 18 days, and when blind-tested, 92% of consumers couldn’t tell the difference between the old synthetic version and the new extract-based one. That’s the sweet spot brands are looking for.
But safety is non-negotiable here. Every extract we sell goes through rigorous testing to meet FDA GRAS (Generally Recognized as Safe) standards, as well as EU EFSA guidelines. A few years ago, a startup tried to use a lemon extract made from discarded citrus peels (a sustainable choice, to be sure) but didn’t test for aflatoxins—a common mold toxin that can grow on improperly stored fruit. We worked with them to refine their storage and extraction process, and now their extract is approved for use in cold beverages and baked goods. The point is, plant extracts aren’t inherently safe just because they come from plants. They have to meet the same safety benchmarks as any other food additive.
Another common use case is flavor enhancement. A lot of plant extracts aren’t just functional—they taste good. For example, our citrus peel extract is made from the essential oils of oranges and grapefruits, and we can adjust the concentration to add a bright, fresh flavor to low-sugar jams or sparkling waters. Traditional sugar masks off notes in low-sugar products, so a small amount of citrus extract can boost brightness without adding extra calories. We also work with herbal extracts like mint and basil for savory products, adding just enough to complement, not overpower, the main flavor—we recently supplied a blend to a salad dressing brand that wanted to cut back on artificial flavorings, and their sales went up 12% in six months after the label change.
But there are limits to what plant extracts can do, and that’s something I always be honest about with clients. They’re not a one-size-fits-all solution. For products with very high heat processing, like crackers or fried snacks, some extracts can break down when exposed to 400°F+ temperatures. That’s why we partner with clients to test our extracts in their specific processing conditions, not just in a lab. We also advise against overusing them—too much of a good thing, like too much peppermint extract in a cookie, can make the product unpalatable. We always work with clients on dosage: most effective extracts are used at concentrations of 0.01% to 0.5% of the final product, which is small enough to keep costs low and flavor intact.
Sustainability is another big reason food brands are turning to plant extracts, and that’s something our team prioritizes as a supplier. A lot of our extracts are made from agricultural byproducts—we take peels, stems, and leaves that would otherwise be thrown away, and turn them into usable extracts. For example, our apple extract is made from the pomace left over after pressing apple juice, reducing food waste and cutting the carbon footprint of the extract by 60% compared to making it from whole apples. That’s a big selling point for brands that want to market their products as eco-friendly, and it’s a win for the planet too.
I’ll be the first to admit that the plant extract industry has had its share of scams. There are suppliers out there selling “rosemary extract” that’s just rosemary oil cut with synthetic antioxidants, or extracts that don’t meet purity standards. That’s why it’s so important for brands to work with suppliers who are transparent about their processes and can provide third-party test results. At our company, we make every batch’s test results available to clients, so they can see exactly what’s in the extract they’re using—no hidden ingredients, no untested compounds.
If you’re a food brand considering adding plant extracts to your products, here’s what I recommend: start small. Test a single extract in one product first, rather than overhauling your entire line. Work with a supplier who will partner with your R&D team, not just sell you a product—someone who can adjust formulations, run stability tests, and troubleshoot if an extract doesn’t work as expected. And don’t forget consumer testing: even if your extract is safe and effective, if customers hate the taste, it won’t matter. We’ve had clients come to us with a great technical solution, but their consumer testing failed because the extract made their product taste bitter—so we helped them adjust the formulation to balance that.
At the end of the day, plant extracts are a proven, safe tool for food manufacturers—when they’re used correctly. They’re not a perfect replacement for all synthetic additives, but they’re a great option for brands looking to clean up their labels, reduce their carbon footprint, and give consumers a product that’s both good for them and good for the planet.
