Can I call my sauce natural, small batch or preservative free?

You can use most of these words if your formula and records back them up, but they fall into three groups with different risks. Some, such as "gluten free," "zero calories" and "low sodium," have exact federal definitions with numbers you must meet, and any nutrition claim costs you the small business exemption from the Nutrition Facts panel. "Natural" has an FDA policy but no regulation. "Small batch," "handcrafted" and award mentions have no federal definition at all, so they rest on being true and specific. This page shows what supports each claim, what invites trouble, and how to word the claims you can stand behind.

Claims at a glance

Claims FDA defines with numbers

Gluten free

Under 21 CFR 101.91, a food can say "gluten-free," "no gluten," "free of gluten" or "without gluten" if it contains no wheat, rye, barley or their crossbreeds as ingredients, no ingredient derived from them that has not been processed to remove gluten, and any unavoidable gluten is below 20 parts per million [1]. A food that inherently contains no gluten also qualifies [1].

Most pepper, vinegar and salt sauces qualify on ingredients alone. The usual problems are malt vinegar (made from barley), regular soy sauce (usually brewed with wheat) and beer. Check every component's ingredient list.

Fermented sauces carry an extra duty. For fermented or hydrolyzed foods, where no valid test method can measure the gluten afterward, the maker must keep records showing the food met the gluten-free standard before fermentation, that cross-contact was evaluated, and what was done about any cross-contact found [1]. Those records must be kept for at least 2 years [1]. If you ferment your own mash, a simple ingredient record for each ferment, with supplier documentation for the salt and any additions, does this job.

Zero calories and sugar free

A "calorie free" or "zero calories" claim needs fewer than 5 calories per reference amount and per labeled serving [2]. The reference amount for hot sauce is 1 teaspoon [3]. Many vinegar pepper sauces meet that number. But FDA requires a food that is calorie free without any special processing or reformulation to say so: the regulation's own example is "cider vinegar, a calorie free food" [2]. So a plain pepper sauce that says "zero calories" also has to disclose that sauces like it are naturally low in calories.

"Sugar free" needs less than 0.5 g of sugars per reference amount and per labeled serving, no ingredient that is a sugar unless it is asterisked as adding a trivial amount, and a statement such as "not a low calorie food" unless the food also meets a calorie claim [2]. Fruit sauces with mango, pineapple or honey rarely qualify.

Both are nutrient content claims. Making either one removes the small business exemption from nutrition labeling for that product, so the bottle then needs a full Nutrition Facts panel [8]. The thresholds for that exemption are on the nutrition panel page.

Low sodium is nearly impossible for hot sauce

"Low sodium" means 140 mg or less of sodium per reference amount, and because a teaspoon is a small reference amount, the food must also meet 140 mg per 50 g [4]. Salt is about 39 percent sodium by weight, so 140 mg of sodium in 50 g works out to roughly 0.36 g of salt, or about 0.7 percent of the sauce's weight. Any sauce salted above that level fails, before counting sodium from other ingredients. Unless your sauce is unsalted or close to it, leave sodium claims alone. "Salt free" requires the food to be sodium free, under 5 mg per serving, with no salt ingredient [4].

The claim with a policy but no rule: natural

FDA has never made a regulation defining "natural." Its longstanding policy is that the term means "nothing artificial or synthetic (including all color additives regardless of source)" has been included in or added to a food that would not normally be expected to be in it [5]. FDA says the policy was not meant to address production methods such as pesticide use or processing methods such as pasteurization, and does not imply any health benefit [5].

For a sauce maker the practical test is the ingredient list:

• Synthetic preservatives such as potassium sorbate and sodium benzoate are generally made by chemical synthesis, so "natural" alongside them is hard to defend.
• Any added color, including colors from vegetable sources such as paprika extract, falls inside the policy's "all color additives regardless of source" [5].
• Thickeners, acids and flavors need supplier documentation of how they are made if you plan to call the sauce natural. If the supplier cannot tell you, do not make the claim.

Forum makers often say that a preservative means you cannot call a sauce "all natural." Under FDA's policy that is a fair reading for synthetic preservatives, though the policy itself names only artificial and synthetic substances and colors [5]. Whether to use sorbate or benzoate at all is covered on the preservatives page.

Claims with no federal definition

No preservatives

No FDA regulation defining "no preservatives" or "preservative free" was found for this page. The closest anchor is FDA's definition of a chemical preservative: a chemical that tends to prevent or slow deterioration when added to food, which expressly excludes salt, sugars, vinegars, spices and oils extracted from spices [6]. On that definition, a sauce preserved by vinegar and salt with no sorbate or benzoate has no added chemical preservative.

The wording still matters. Vinegar is what keeps an acidified sauce safe, so "preservative free" on a vinegar sauce can strike a buyer or inspector as misleading. Wording that matches the regulation is safer: "No added chemical preservatives," or simply "No sorbate or benzoate." If your formula does contain a chemical preservative, the ingredient list must name it with its function [6].

Small batch, handcrafted, homemade

These words have no federal definition, which means they are judged on whether they are true and not misleading. Back them with records. If your label says "small batch," your batch records should show batches you would describe that way, and the claim should still be true after you move to a copacker. "Homemade" has a further problem: in many states a home-produced sauce sold under a cottage food law must carry a specific state statement, and a licensed product that says "homemade" can confuse an inspector about which route you are on. The state rules page covers those statements.

Award mentions

An award is a strong selling line and an easy one to overstate. State it exactly: the competition, the year, the category and the placing, for the sauce that won. "First Place, Fruit Sauce, 2025 [competition name]" is a claim you can prove. "Award-winning" on every bottle in the range, when one sauce placed once, is not. Keep the certificate or results page with your records, and check the competition's rules on using its name or logo. The expos and awards page covers whether entering is worth the fee.

Health and heat claims

A health claim ties a food or substance to a disease or health condition, and it is regulated under 21 CFR 101.14 [7]. The health claims FDA has authorized by regulation, listed in 21 CFR 101.72 through 101.83, cover subjects such as calcium and osteoporosis, sodium and hypertension, and fiber and heart disease; none concerns capsaicin or chili peppers [7]. Lines such as "boosts metabolism" or "fights inflammation" on a sauce label invite regulatory trouble and also cost you the nutrition labeling exemption [8].

Heat claims are a different matter. A Scoville figure or a 1 to 10 heat scale is not a nutrition claim, but a number on the label should come from a test of the finished sauce. How to get a sauce tested and how to state the result is on the heat on the label page.

Before you print a claim

1. Write down what each claim means on your label, in one sentence.
2. Check it against the table above and the rule it points to.
3. File the proof: formula, supplier statements, test results, batch records or the award certificate.
4. Recheck every claim when you change a formula, a supplier or your production site.

Dates and lot codes are the last items most makers add to the label. What to print, and how to tie a code to a batch, is on the best-by dates and lot codes page.
