Raw vs Processed Honey: How to Tell If Honey Is Raw

Reviewed by Michael R. · Last Updated October 24, 2026 · How we review

You usually can’t tell whether honey is raw by looking at the jar. Raw honey has been strained but not heated beyond hive temperature and not fine-filtered, and the best proof is a producer who can say how warm it got and what it was filtered through. Processed honey, the clear “regular” honey on many supermarket shelves, is typically heated and fine-filtered. Both are mostly the same sugars. Raw honey keeps more heat-sensitive enzymes and most of its pollen, and it crystallizes sooner, which is normal. Neither kind is safe for babies under 12 months.

Below, we separate the two things “processed” can mean, show how much honey’s main enzyme survives each temperature in lab data, and rate every common clue.

Educational information only, not medical advice. For infant feeding, follow the CDC’s guidance on foods to avoid.

Key Takeaways

• There is no official U.S. federal definition of “raw” honey. The word on a label is a producer’s claim, not a certification.
• Heat and filtering are separate steps. “Unfiltered” says nothing about heat, and “unpasteurized” says nothing about filtering.
• No single clue proves honey is raw. Cloudiness and fast crystals suggest “not fine-filtered”; only lab markers and the producer speak to heat.
• In lab tests, the enzyme invertase starts declining at hive temperature (95 °F) and is almost gone after a day at 149 °F.
• Sugar, calories and infant-botulism risk are the same. No honey for children under 12 months.

What “Raw” and “Processed” Actually Mean

“Raw” has no legal meaning in the United States. The National Honey Board, the industry’s research and promotion body, says so directly:

“While there is no official U.S. federal definition of “raw” honey, it generally means honey that has not been heated or filtered.”

National Honey Board, Honey FAQ

“Processed” has no fixed definition either, and two separate steps hide inside it. Heating slows crystallization and kills yeasts, but it costs enzymes. Filtering removes fine particles, pollen and air bubbles, which makes honey clear and delays crystallization. A jar can have had one without the other.

At the raw end, honey is spun from the comb, strained through a sieve, left to settle so bubbles rise, and bottled, perhaps warmed slightly to help it flow. At the processed end it is heated well above hive temperature, pressure-filtered, often blended, and bottled to stay clear for months. Our guide to how honey is processed from comb to jar walks through each stage.

How to Tell If Honey Is Raw: What Each Clue Proves

Appearance clues mostly speak to filtering, because filtering changes how honey looks. Heat leaves almost no visible mark, so it is the harder question.

The lab row is where most online advice goes wrong. A 2001 study by Greek honey-quality researchers found that each marker has limits, and that using both is safer:

“HMF can be used for the determination of overexposure to heat while invertase can detect gentle heating.”

Sophia Karabournioti and P. Zervalaki, “The Effect of Heating on Honey HMF and Invertase,” Apiacta 4, 2001

The paper adds that invertase starts at very different levels in different honeys, so one reading can’t say on its own whether a jar was heated, and that HMF does not easily reveal exposure to 104 to 122 °F (40 to 50 °C). The international Codex standard, which is not U.S. law, allows up to 40 mg/kg HMF and requires diastase of at least 8 Schade units in most honey, so a processed jar can pass both. See our diastase number guide.

Questions to Ask the Beekeeper or Seller

Because a label is only a claim, the person who handled the honey is your best source:

1. What is the hottest the honey has been, and for how long? Near hive temperature costs little; the ladder below shows steep losses by 131 °F.
2. How do you melt crystals before bottling? A warming cabinet or water bath is gentle; heated knives, bucket heaters and microwaves can overheat honey in spots. See how to reliquefy crystallized honey without damage.
3. Is it strained or filtered, and through what? A coarse sieve leaves pollen in; pressure filtering takes it out.
4. Is it all your own honey, from one place, with nothing added? “Raw” says nothing about blends. Our guide to vetting real local honey goes deeper.
5. When was it harvested and bottled, and how was it stored? The Greek paper calls diastase and HMF measures of “the heat and storage history,” so months in a hot shed leave the same marks as pasteurizing. If the honey has been lab-tested, ask for the date and HMF.

Vague answers are a reason to look elsewhere. For national brands, see the best raw honey brands you can actually buy, and for a comparison with two other labels, raw vs Manuka vs local honey.

Raw Is Not the Same as Real

Raw describes how honey was handled; real describes what is in the jar. A heated, filtered jar can be 100% honey, and because “raw” is an unverified claim, it guarantees nothing about what else is in the jar. The National Honey Board adds that ultrafiltration, which filters water-thinned honey at the molecular level, makes a colorless product that is not considered honey in the U.S.

If your worry is added syrup, you need different tools. See how to tell if honey is fake and the guide to detecting adulterated honey. The True Source Certified label tracks where honey came from; it doesn’t mean raw.

What Heat Does: The Enzyme Ladder

Honey’s most heat-sensitive ingredients are its enzymes, such as the invertase bees add to split sucrose into glucose and fructose. Because enzymes are proteins, heat unfolds them, and they don’t recover.

The Karabournioti and Zervalaki study held five honeys at set temperatures for 24 hours and measured the invertase left and the HMF (hydroxymethylfurfural) formed (full paper, PDF). HMF is not present in fresh honey and forms with heat and age. One of the five was sunflower honey. We converted their numbers into the share of invertase that survived:

The 40 mg/kg line is the HMF limit in the Codex Alimentarius Standard for Honey, which allows 80 mg/kg for honey from tropical climates. Three caveats. These were 24-hour holds, and commercial heating is usually much shorter, so a jar heated for minutes loses less. Also, 95 °F is about where bees keep their brood nest, so “raw” means not heated beyond that. And honeys differ in heat resistance (pine and orange held up better), so this is a guide, not a prediction for one jar.

Gentle warming to dissolve crystals does little harm; the big losses start near 130 °F. See how heating alters honey enzymes for time as well as temperature.

What Filtering Removes

The USDA’s United States Standards for Grades of Extracted Honey define the two terms separately. Strained honey has had most particles, such as bits of comb and propolis, removed; pollen grains, small air bubbles and very fine particles would not normally be removed. Filtered honey has had all or most of the fine particles, pollen grains and air bubbles removed.

Pollen is honey’s fingerprint: the Greek study identified its honeys’ botanical origin partly by pollen analysis, so removing pollen removes a way to check where a honey came from. Filtering also removes the particles crystals grow on, so honey stays liquid far longer, the National Honey Board says. The international standard goes further than U.S. rules:

“No pollen or constituent particular to honey may be removed except where this is unavoidable in the removal of foreign inorganic or organic matter.”

Codex Alimentarius, Standard for Honey (CODEX STAN 12-1981), section 3.1

It also says honey filtered to remove pollen significantly must be labeled “filtered honey.” For the range in between, see raw honey filtration levels explained and pollen content in unfiltered honey.

Why Packers Heat and Filter

The National Honey Board says packers filter because many consumers want honey that stays liquid and looks brilliantly clear. Heating kills yeasts, which matters because honey with too much water can ferment: USDA Grade A requires at least 81.4% soluble solids, about 18.6 to 18.7% moisture. Beekeepers get the same protection by extracting only ripe honey. Warm honey is also thinner, so it moves through pumps and filters more easily. A small beekeeper faces fewer of these pressures, so raw honey is easier to find locally.

Nutrition and Safety

• Sugar and calories are essentially the same.
• Raw honey keeps more enzymes and pollen, but the National Honey Board says honey’s pollen is too small an amount to affect its nutrient value.
• On antioxidants the evidence is mixed. A 2012 National Honey Board study found that processing reduced pollen but did not affect nutrient content or antioxidant activity. A 2023 review concluded that thermal processing adversely affects honey’s antioxidant and antimicrobial activity. The Board is an industry body.
• Pollen can cut both ways. Healthline advises people with pollen allergies to speak with a doctor before trying raw honey. The National Honey Board knows of no scientific evidence that local honey relieves allergies.

On infant safety, raw and processed honey are the same. The CDC says not to give a child honey before 12 months, because it can cause botulism. Clostridium botulinum spores are heat-resistant, so pasteurization doesn’t always kill them, and “processed” doesn’t mean baby-safe. See our guide to honey and infant botulism.

A North Dakota Example: Why Raw Honey Sets So Fast

USDA says North Dakota ranked first in honey production for the twenty-first consecutive year on its 2024 crop, with 36.3 million pounds from 490,000 colonies. Glucose-rich honey from flowers such as canola, alfalfa and clover can set within weeks, so a strained, unheated jar often turns firm long before a filtered one. See why some honeys crystallize faster.

Frequently Asked Questions

How can you tell if honey is raw?

Not with certainty from the jar. Cloudiness, specks and early crystals suggest it wasn’t fine-filtered, but none shows it stayed cool. Ask the producer how warm it got and how it was strained.

Is raw honey healthier than processed honey?

Slightly different, not dramatically healthier. Raw honey keeps more enzymes and pollen, but sugar and calories are the same and studies disagree on antioxidants.

At what temperature does honey stop being raw?

There’s no legal cutoff. Invertase declines from about 95 °F and falls sharply above roughly 130 °F.

Why does raw honey crystallize faster?

Pollen, tiny wax particles and air bubbles give glucose crystals something to grow on, and filtering removes them. Crystallized honey isn’t spoiled and can be gently rewarmed.

Is unfiltered, pure or organic honey the same as raw?

No. Unfiltered means pollen was left in, but the honey may have been warmed. “Pure” means nothing was added. Organic covers production, and Healthline notes no rule stops organic honey from being pasteurized.

Does pasteurized honey kill botulism spores?

Don’t count on it. The spores are heat-resistant, and the CDC advises no honey for children under 12 months, raw or processed.

The Bottom Line

Raw and processed honey are the same food handled differently, and heat and filtering are separate choices. The difference is real but modest, and no jar can prove its own history. If you want the enzymes and pollen, buy from a producer who can tell you how warm the honey got and what it was strained through, and expect it to crystallize.
