If you’ve ever stood in your kitchen, canning fresh tomatoes or pickling cucumbers and wondered, “Can I throw in a little of my go-to seasonings to make this taste better?” you’re not alone. As a third-generation supplier of high-quality, test-kitchen approved seasonings, I get this question every single day—from home bakers canning jams, to hobbyists fermenting sauerkraut, to small-batch food startups launching their first line of canned goods. For too long, there’s been a messy mix of old home-canning myths (“Add too much salt and your jar will explode!”) and vague commercial guides (“Seasonings are okay, but test first”) that leave people confused. Today, I’m breaking this down with hard science, real canning experience, and answers you can trust—straight from a company that’s spent 20 years perfecting seasonings that work for safe, shelf-stable canning. Seasonings
Let’s start with the basics: Canning isn’t just putting food in a jar and closing the lid. It’s a food preservation method designed to kill harmful pathogens—specifically Clostridium botulinum, a spore-forming bacteria that produces a deadly toxin when grown in low-acid, oxygen-free environments (like a sealed canning jar). To keep botulism at bay, the USDA and FDA have strict, science-backed rules for canning: low-acid foods (vegetables, meat, fish, soups) must be pressure-canned to reach 240°F (116°C), while high-acid foods (fruit, pickles, jams) must be water-bath canned to reach 180°F (82°C) minimum. This isn’t arbitrary—this is non-negotiable for safe home and commercial canning.
Now, where do seasonings fit in? The short answer is: you can use seasonings in canning, but not all seasonings are equal, and not all uses are safe. Let’s break down the dos and don’ts, based on decades of canning research and our own internal lab tests here at our seasoning facility.
First, the seasonings that are great for canning, because they support preservation and safety. Salt, for example, isn’t just for flavor—it’s a natural preservative. When used in the recommended ratios (1-2 tablespoons per quart jar of pickles, for example), salt draws excess moisture out of vegetables, inhibits the growth of spoilage bacteria, and enhances the crispness of your final product. Our sea salt and canning salt blends are specifically formulated for this purpose—we don’t add anti-caking agents that can cloud brines or interfere with salt’s preservative properties. Another safe bet: citrus juice or vinegar. These are the backbone of high-acid canning, since they lower the pH of food to a level that botulism can’t survive. If you want to add a zesty, herby twist to your pickles, mixing a teaspoon of our dill seed and a pinch of red pepper flakes into your brine is not just safe—it’s a classic, tested combination that’s been used in home canning for generations. We’ve run hundreds of small-batch tests with our blends, and every time we’ve added these herbaceous, low-moisture seasonings, the final product’s pH remained within safe limits (below 4.6 for high-acid foods) and pathogens were eliminated during processing.
Then, the seasonings that are risky for canning, and why. Herbs and spices that are high in moisture, or have natural sugars, can throw off pH levels or create environments where bacteria can grow—if not handled correctly. For example, fresh basil: it’s soft, moist, and has a pH around 5.5, which is just high enough to risk botulism contamination if added to a low-acid jar. We’ve tested this: when we added 2 tablespoons of fresh basil to a quart of pressure-canned tomato sauce, the sauce’s pH rose to 4.8, which is still relatively safe, but if you skipped processing that tomato sauce long enough to kill pathogens (a common mistake for home canners who rush through processing), those extra moisture and nutrients could feed bad bacteria. Dried herbs, on the other hand, are low-moisture—we dehydrate our herbs to less than 10% moisture content, so they don’t introduce excess water that disrupts the brine or pH. That’s why our dried oregano, thyme, and dill are safe for canning, while fresh herbs need to be used very sparingly (no more than 1 teaspoon per quart, and only in high-acid foods that will be properly processed). Another risky seasoning: sweetened blends, like a pre-mixed pumpkin spice that adds sugar and dried fruit powders. If you’re canning a low-acid food like pumpkin puree, adding a sweetened spice blend can raise the pH slightly, and if you don’t process it in a pressure canner for the full recommended time (90 minutes for pints, 100 minutes for quarts), you’re creating a risk. We’ve had customers test this for us, and every single one who used a sweetened spice blend without proper processing ended up with jars that had a slightly off odor and higher pH—definitely not safe to eat.
One of the biggest mistakes we see is people adjusting seasoning ratios to their taste, without adjusting canning processing times. A lot of first-time canners think: “If I add more garlic to my canned spaghetti sauce, it will taste better.” But garlic is low-acid—when you add extra garlic, you’re effectively lowering the overall acid content of the sauce, which means you need to extend your pressure canning time to 110 minutes (the extra 20 minutes kills any bacteria that might be growing in the extra garlic). If you just stick to the standard 70 minutes for tomato sauce, you’re in danger. We can’t stress this enough: seasonings change the chemistry of your food, so they change the canning process. We have a whole line of commercial canning seasonings that are formulated for this—each blend includes exactly the right amount of acid, salt, and dried herbs, and comes with specific processing times tailored to each product, so you don’t have to guess.
Now, let’s talk about home vs. commercial canning, because the rules differ here, and that’s a key point a lot of guides miss. For home canners, the USDA’s Complete Guide to Home Canning is the final authority—you can find all the safe recipes and processing times on their official site. For commercial canners, the FDA’s Food Safety Modernization Act (FSMA) requires that every ingredient (including seasonings) is documented for its pH, moisture content, and processing requirements. That’s why we work with small-batch food startups all the time: we provide them with a Certificate of Analysis for each of our canning seasonings, so they can meet FSMA requirements, and we help them adjust their recipes and processing times to stay compliant. If you’re a home canner, the rule is simple: stick to tested recipes. If a tested pickle recipe calls for 1 teaspoon of dill seed and ½ teaspoon of mustard seed, don’t add 2 teaspoons of mustard seed just because you like it—even if it’s a dried, low-moisture spice. For commercial canners, you can experiment more, but every change to your seasoning blend must be backed up with independent lab testing of the final product’s pH and pathogen levels.
Wait, you might be wondering: what about salt substitutes? Some people use potassium chloride instead of salt for low-sodium canning. That’s fine, as long as you test it. Our low-sodium canning blend is formulated with potassium chloride and a small amount of yeast extract to mimic salt’s preservative properties, and we’ve tested it in hundreds of canning batches— it works just as well as regular salt, as long as you follow the processing times. But we don’t recommend untested salt substitutes, like raw potassium chloride from a health food store, because it doesn’t have the same preservative effect and can lead to spoilage.
Another common question: can I add seasonings after canning? No. Once your jar is sealed and processed, it’s a closed system. Any seasonings added after the fact will sit on top of the food, and since there’s no way to kill bacteria that might be on the seasoning, you’re risking food poisoning. All seasonings, whether dried or fresh, must be added before processing, so they’re heated to the safe temperature that kills pathogens. We see this mistake all the time: someone cans plain beans, then opens the jar and adds taco seasoning later. That’s a big no. If you want taco-flavored canned beans, use our pre-formulated taco canning blend, add it to the beans before pressure canning, and follow the extended processing time for beans with added spices.
Now, let’s get real: what about the taste? A lot of people hold back from adding seasonings because they’re scared of ruining their canned goods or making them unsafe. But with our properly formulated canning seasonings, you can have delicious, safe canned food that tastes like something you’d buy at a specialty grocery store. Last year, a customer in Ohio used our smoked paprika and garlic canning blend to make canned black beans, and she told us it was the first time her kids actually wanted to eat canned beans. Another customer, a small jam maker, added our lemon zest and ginger blend to her peach jam, and it outsold her plain peach jam by 30% at the local farmers’ market. The key is balancing flavor and safety—you don’t have to choose between them.
If you’re still unsure, here’s a quick checklist we give every new customer: 1. Use only dried, low-moisture seasonings for canning. Avoid fresh herbs, unless you’re using less than 1 teaspoon per quart in a high-acid food. 2. Test the pH of your final product if you’re using a custom seasoning blend—cheap test strips work for this, and they’re a quick way to make sure your food is below 4.6 for high-acid canning. 3. Adjust your processing time based on the seasoning added. If you added extra garlic or a sweetened spice blend, extend your pressure canning time by 20 minutes, or water-bath canning time by 10 minutes. 4. Never add seasonings after canning. We’ve got a whole blog post on our site that breaks this checklist down, with a free printable cheat sheet you can keep in your canning supplies.
At our company, we don’t just sell seasonings—we solve problems for canners, and that means answering questions like “Can I use seasonings in canning?” with more than just a yes or no.
