What is Raw Honey? How It Differs from Supermarket Honey
Raw honey is honey that has not been heated above approximately 40°C or mechanically filtered to remove pollen, propolis, and beneficial enzymes. Supermarket honey is typically pasteurised at temperatures above 60°C and ultrafiltered — a process that extends shelf life and creates a clear, uniform appearance but destroys the biological compounds that make honey nutritionally and therapeutically meaningful.
Key Points
- Raw honey retains glucose oxidase, the enzyme that produces natural hydrogen peroxide activity
- Pasteurisation above 40°C deactivates key enzymes and reduces antioxidant compounds
- Ultrafiltration removes pollen — the primary way scientists authenticate honey's floral origin
- Labels like "pure" or "natural" do not mean raw — you need to check the fine print
- Forest Fresh Jarrah honey is always raw and independently TA-tested to verify bioactivity
Walk down the honey aisle in any Australian supermarket and you will see dozens of golden jars all claiming to be "pure" or "natural." Most of them are technically honey — but the substance inside is a long way from what came out of the hive.
The difference comes down to processing. Raw honey is bottled as close to its natural state as possible: lightly strained to remove wax and debris, never heated above temperatures a hive would naturally reach in summer. The honey you find in most supermarkets has been pasteurised and filtered to prevent crystallisation, extend shelf life, and achieve the clear, uniform look that consumers have been trained to associate with quality. That clarity comes at a cost.
Understanding what happens during processing — and why it matters — is the first step to making a genuinely informed choice at the shelf.
What Happens When Honey is Processed?
Commercial honey processing typically involves two steps: pasteurisation and filtration.
Pasteurisation heats honey to temperatures between 60°C and 80°C. The goal is to kill wild yeasts that could cause fermentation and to delay crystallisation. It works. But heat is indiscriminate — it doesn't just target yeasts. It also deactivates glucose oxidase, the enzyme responsible for generating hydrogen peroxide when honey is diluted. Glucose oxidase is central to honey's antimicrobial properties. Remove it, and you remove a core part of what makes honey biologically active.
Ultrafiltration passes honey through fine filters under high pressure to remove pollen grains, propolis particles, and other microscopic material. This produces the crystal-clear, slow-to-crystallise honey that dominates supermarket shelves. It also removes pollen — the botanical fingerprint that allows scientists to verify where honey came from and what flowers the bees visited. Filtered honey is harder to authenticate and easier to adulterate.
The result is a product that tastes like honey and contains fructose and glucose — but has been stripped of much of its biological complexity.
The Science of Raw Honey's Bioactivity
Raw honey's value lies in its active compounds:
Glucose oxidase is an enzyme bees add to nectar during collection. When honey is diluted (for example, on a wound or in the digestive tract), glucose oxidase catalyses the conversion of glucose into gluconic acid and hydrogen peroxide. That hydrogen peroxide is a key part of honey's antimicrobial action. Research published in PLOS ONE by Irish, Blair, and Carter (2011) confirmed the antibacterial activity of Western Australian honeys — activity that depends on these enzyme systems being intact.
Antioxidants — including flavonoids and phenolic acids — are present in raw honey at concentrations that vary by floral source. These compounds are heat-sensitive. A 2023 study by Hossain and Locher found that WA honeys "at times exceeded NZ Manuka honey" in antioxidant and antibacterial activity, underscoring why preserving these compounds through minimal processing matters.
Pollen in raw honey functions as a prebiotic substrate. Research by Schell et al. (2022) in Frontiers in Nutrition identified Jarrah honey as a meaningful source of prebiotic compounds supporting gut microbiome diversity — activity that requires the honey to be unadulterated.
Propolis particles carry their own antimicrobial and anti-inflammatory properties and are retained in genuinely raw honey.
None of these benefits survive aggressive heat treatment.
How to Tell If a Honey is Truly Raw
Reading a honey label requires a small amount of scepticism. Here is what to look for:
| Label claim | What it actually means |
|---|---|
| "Pure honey" | No additives — but may still be pasteurised |
| "Natural honey" | Marketing language with no regulatory definition |
| "Raw honey" | Unheated, unfiltered — but check for TA/lab testing to verify |
| "Organic" | Pesticide-free farming, not a processing claim |
| "Active" | May indicate measurable antimicrobial activity — look for TA or MGO rating |
Look for: 1. An explicit statement that honey is unpasteurised or unheated 2. A Total Activity (TA) rating or equivalent — this can only be achieved if bioactivity is intact 3. Country and region of origin (WA or Australian is a meaningful quality signal) 4. A certificate of analysis or independent lab testing claim 5. The presence of natural crystallisation — raw honey often crystallises over time, which is a positive sign of authenticity
If a honey is crystal-clear, pourable, and has no TA or activity rating, it is almost certainly pasteurised and filtered.
Forest Fresh Jarrah: Raw by Default, Tested by Verification
Forest Fresh Honey operates on a simple principle: every jar leaves the hive in its most natural state. Our Jarrah honey is never heated above temperatures that would deactivate enzymes, and it is never ultrafiltered. But we don't ask you to take that on faith.
Every batch undergoes 5 independent laboratory validations, including Total Activity (TA) testing that confirms the hydrogen peroxide activity of the honey is intact and measurable. Our Jarrah Platinum TA50+ carries an independently verified TA rating of 50 or above — equivalent to MGO 4000+ in Manuka terms — which is only possible because the honey is genuinely raw and biologically active.
That's the Jarrah Factor™: raw is the starting point, not the selling point.

Frequently Asked Questions
Q: Is raw honey safe to eat? A: Yes, for most people. Raw honey is a whole food that has been consumed safely for thousands of years. The one exception is infants under 12 months, who should never be given any honey due to the risk of infant botulism. For adults and children 12 months and older, raw honey is safe and beneficial.
Q: Does raw honey crystallise? A: Yes — and that's a good thing. Crystallisation is a natural property of high-glucose, unadulterated honey. It does not mean the honey has spoiled. Gently warming the jar in warm (not hot) water will return it to a liquid state. If a honey never crystallises, it has likely been processed to prevent this.
Q: What temperature kills enzymes in honey? A: Research indicates that heating honey above approximately 40°C begins to deactivate glucose oxidase and other heat-sensitive enzymes. Commercial pasteurisation typically reaches 60–80°C, which significantly reduces enzyme activity. Raw honey producers keep temperatures below 40°C throughout processing.
Q: Can you heat raw honey without destroying it? A: Brief, gentle warming below 40°C is fine — for example, stirring into warm (not boiling) water. Adding raw honey to very hot beverages like boiling tea will reduce its bioactivity. For maximum benefit, add honey to warm or room-temperature food and drinks.
Q: What is the difference between raw honey and organic honey? A: These are separate claims. Organic honey refers to the farming practices around the beehives — specifically pesticide-free foraging areas. Raw honey refers to how the honey is processed after harvest. A honey can be organic but pasteurised, or raw but not certified organic. The most beneficial honey is ideally both raw and from a clean, natural environment.
Q: How does raw honey differ from active honey? A: All genuinely active honey should be raw — bioactivity requires intact enzymes and compounds that are destroyed by heat processing. But not all raw honey is measurably active. "Active" or "bioactive" honey has a verified antimicrobial activity rating (TA, UMF, or MGO). Raw is a prerequisite; activity is the confirmation.
Q: Why does supermarket honey look so clear? A: The clarity comes from ultrafiltration and pasteurisation. Filtering removes pollen and particles that cause cloudiness; heating and filtering together prevent crystallisation. Many consumers associate clarity with purity — but in honey, cloudiness and crystallisation are actually signs of minimal processing and higher quality.
Q: Is WA Jarrah honey always raw? A: Reputable WA Jarrah honey producers sell their honey raw, because the antimicrobial activity that defines Jarrah honey depends on the hydrogen peroxide pathway — which requires intact glucose oxidase. Pasteurising Jarrah honey would destroy the very properties that make it valuable. Always look for a TA rating to confirm bioactivity is present.
