The Effects of Heating on Manuka Honey: Unveiling the Truth

Can you add Manuka honey to hot tea or use it in cooking? Yes, but heat can affect some of honey’s natural compounds. Here’s what to know and how to enjoy Manuka honey without exposing it to too much heat.

Can I Safely Cook with Manuka Honey?

You can cook with Manuka honey, but adding it toward the end of cooking is a good option when you want to preserve more of its original flavor and character. 

What Happens When Manuka Honey Is Heated?

Heating Manuka honey does not suddenly make it “bad,” but temperature and time can change some of its natural characteristics.

The important thing is that not everything in honey responds to heat in the same way.

MGO

MGO, or methylglyoxal, is one of the key compounds measured in Manuka honey. It is reasonably stable under normal storage and everyday use, but research has shown that sufficiently high heating can reduce its concentration.

That means briefly stirring Manuka honey into a warm drink is very different from exposing it to prolonged high-temperature cooking.

Natural Enzymes

Honey naturally contains enzymes, but they can be affected by heat. Enzyme activity is also one of the things used to check whether honey has been exposed to too much heat.

Leptosperin

Leptosperin is a natural marker found in Manuka honey. Unlike some enzymes, it appears to be fairly stable when exposed to warmer temperatures.

Flavor, Aroma, and Texture

Heat can also change the experience of the honey itself. Longer or hotter exposure can alter its aroma, deepen its color, and change its flavor and texture.

So rather than thinking of one exact temperature where Manuka honey suddenly loses its qualities, it is better to think about both how hot it gets and how long it stays hot.

Does Temperature or Heating Time Matter More?

Both matter. A short exposure to warmth is different from keeping honey at a high temperature for several minutes. In general, the hotter the honey gets and the longer it stays there, the more opportunity there is for its natural composition, aroma, and texture to change.

Research on Manuka honey has found significant reductions in MGO during heating at 90°C (194°F), showing that high-temperature processing can affect this important Manuka compound.

That is why simple uses, such as adding honey to a drink after it has cooled slightly, are very different from baking or boiling it for an extended period.

How to Use Manuka Honey With Warm Foods and Drinks

You don’t have to give up warm foods and drinks to enjoy Manuka honey. A few small changes to when you add it can help limit unnecessary exposure to high heat.

In Tea or Coffee

Make your drink as usual, then let it cool a little before stirring in the honey.

Over Oatmeal or Breakfast Foods

Cook your breakfast first and add the honey just before eating. This gives you the sweetness without heating the honey for a long time.

With Cooked Foods

Using honey as a glaze or finishing touch? Add it near the end of cooking, or drizzle it over the food once it has cooled slightly.

In Baking

Manuka honey can be used in baking, but oven heat can change some of its natural qualities. If you want to keep more of its original character, use it as a drizzle or topping instead.

The simple rule is to add Manuka honey after cooking whenever you can. That way, you can still enjoy it with warm foods and drinks without putting it through more heat than necessary.

From Hive to Jar: How Manukora Protects Quality 

At Manukora, careful handling starts long before the honey reaches your kitchen.

Our Manuka honey is sourced from New Zealand, tested for its MGO level, and traceable through the QR code on every jar. That gives you a clearer view of where your honey came from, how it was tested, and the batch behind it.

We also follow The Art of Ethical Beekeeping™, with care for the bees and their environment built into the way our honey is produced.

The result is a rich, creamy Manuka honey with a distinctive flavor and transparent journey from hive to jar. Whether you enjoy it straight from the spoon, in a warm drink, or as a finishing touch on food, Manukora makes it easy to know more about the honey you’re choosing.

FAQs

Can I put Manuka honey in hot tea?

Yes. Let freshly brewed tea cool for about 30–60 seconds before stirring in Manuka honey to limit unnecessary exposure to very high heat.

Does heating destroy MGO in Manuka honey?

Not instantly. MGO can tolerate some warmth, but research shows sufficiently high or prolonged heating can reduce its concentration.

What temperature damages Manuka honey?

There is no single temperature where every component suddenly changes. The effect depends on both temperature and how long the honey is heated.

Can I cook with Manuka honey?

Yes. You can cook with it, but adding it near the end of cooking helps preserve more of its original flavor and characteristics.

Can I bake with Manuka honey?

Yes, but baking exposes it to prolonged high heat. If you want to preserve more of its original qualities, add it after baking instead.

Does heating change the taste of Manuka honey?

It can. Higher or prolonged heat may change the honey’s aroma, color, flavor, and texture.

How should I store Manuka honey?

Keep it tightly sealed in a cool, dry place away from direct sunlight and unnecessary heat
