Is citric acid from lemons?

Usually not. Most citric acid in packaged food is made by fermenting sugar with the mold Aspergillus niger. It is the same molecule found in citrus fruit.

The FDA lists citric acid as generally recognized as safe under 21 CFR 184.1033 for use in food at good manufacturing practice levels.

Does citric acid lower a product’s score?

No. It is not one of the groups the checker flags, so only other ingredients on the label change the score.

What is citric acid? How it is made, why it is added and where it shows up.

Updated October 29, 2026

Citric acid is mostly made by fermenting sugar with a mold, not squeezed from lemons. Why it is added to food, which shelves list it most, and how our checker treats it.

Quick answer

Citric acid is a sour-tasting acid found naturally in citrus fruit. The citric acid added to packaged food is made mostly by fermenting sugar with the mold Aspergillus niger, not by squeezing lemons. Makers add it for tartness, to control acidity and to help keep food from spoiling. The FDA lists it as generally recognized as safe, and our checker does not flag it.

01 · A closer look

Where citric acid comes from.

Citric acid occurs naturally in lemons, limes and other citrus fruit, but squeezing fruit is not how it is made for food. Industrial citric acid is produced by feeding sugar from corn or sugar cane to the mold Aspergillus niger in fermentation tanks, then purifying the acid. The result is chemically the same molecule as the citric acid in a lemon.

02 · A closer look

What the FDA says.

The FDA affirms citric acid as generally recognized as safe (GRAS) for direct addition to food, with no limit other than current good manufacturing practice. It is one of the most common acidulants on ingredient labels.

21 CFR 184.1033: citric acid

03 · A closer look

Why it is on the label.

It does three jobs: it adds sour flavor (candy, sparkling drinks), it sets acidity so that jams gel and preservatives work, and it slows browning and spoilage in fruit products. A label that lists citric acid is not claiming the food contains lemon juice. If lemon is in the product, the label names lemon juice separately.

04 · A closer look

How our checker treats it.

Citric acid is not one of the nine additive groups the checker flags, so it does not change a product’s score by itself. A short label with citric acid can still score 100. If you avoid it for a personal reason, such as a sensitivity, search the label for the word; we do not give medical advice.

Citric acid in our catalog

Of the 4,729 products whose full ingredient list we have read in the last 90 days, 670 (from 319 brands) list citric acid. The checker does not treat it as an additive to avoid, so a label that lists only citric acid is not marked down for it. Below are up to 12 of them, one per brand; open a product to see its full label and the date we read it.

How the clean score works

No setup needed, and strict: a full 100 needs every additive group clear and a verified organic claim (animal foods also need a verified grass-fed or pasture-raised claim; wild seafood and salt, which have no USDA organic standard, are scored without the organic points, and plant-based milks, cheeses and proteins without the feeding claim). Points: the nine additive groups (seed oils, artificial dyes, MSG, artificial sweeteners, carrageenan, artificial preservatives, hydrogenated oils, corn syrups, banned-abroad additives) share 60 points equally — not found earns a group’s full share, “may contain” earns half, listed earns 0; a verified organic claim is worth 25; a verified grass-fed or pasture-raised claim is worth 15 and counts only for animal foods. No claim, or an expired or unverified claim, earns nothing, so products without those claims cannot reach 100. Unverified or expired ingredient labels receive no score. Equal scores are equal. Ties are ordered by brand. Unknown and stale evidence never passes “Only show matches.” Producer claims and prices do not affect this score. This is not a nutrition, allergy, or safety rating.
