What is the main difference between raw honey and pasteurised honey?

4 min read

Globally, honey is one of the safest foods, thanks to its low moisture content and high acidity. So, what is the main difference between raw honey and pasteurised honey? It's the processing method, specifically the application of high heat, which significantly impacts the honey's nutritional content, physical properties, and overall character.

Quick Summary

This article explores the fundamental differences between raw and pasteurised honey, focusing on the high-heat processing applied to pasteurised varieties. It details how this heat treatment affects nutritional value, texture, and flavour. The comparison will help consumers understand the benefits of each type.

Key Points

  • Processing Method: The core difference is that raw honey undergoes minimal heat and filtration, while pasteurised honey is intensely heated and ultra-filtered for clarity and delayed crystallization.

  • Nutritional Content: Raw honey retains more natural enzymes, antioxidants, vitamins, pollen, and propolis, which are largely destroyed or removed during the pasteurisation process.

  • Appearance and Texture: Raw honey is typically cloudy, opaque, and prone to natural crystallization. Pasteurised honey is consistently clear, smooth, and liquid for longer.

  • Flavor Profile: Raw honey offers a more robust, complex, and floral flavour, whereas the heating process gives pasteurised honey a milder, less nuanced taste.

  • Intended Use: Raw honey is often preferred by those seeking health benefits and a natural product. Pasteurised honey is ideal for cooking and those who prefer a liquid, uniform sweetener.

  • Safety: Both raw and pasteurised honey can contain Clostridium botulinum spores, making them unsafe for infants under 12 months. Pasteurisation does not eliminate this risk.

The world of honey offers consumers two primary choices: raw or pasteurised. While both originate from the nectar of flowers, the journey from hive to jar is distinct and results in vastly different end products. The main difference is the heat treatment and filtration applied to pasteurised honey, which strips it of many of the naturally occurring compounds that define raw honey.

What is raw honey?

Raw honey is honey in its most natural state, taken directly from the honeycomb. Beekeepers typically strain it to remove larger impurities like beeswax and hive debris, but it is not subjected to high-heat pasteurisation or ultra-filtration. This minimal processing ensures that it retains its natural enzymes, antioxidants, vitamins, and minerals.

Characteristics of raw honey include:

  • Appearance: Often cloudy or opaque due to the presence of fine particles like pollen, propolis, and wax.
  • Texture: Thick, and tends to crystallize more quickly than pasteurised honey.
  • Flavour: A more complex, robust, and distinct flavour profile that reflects the specific floral sources from which the bees collected nectar.

What is pasteurised honey?

Pasteurised, or regular commercial, honey is subjected to high heat (around 63–77°C) and often ultra-filtered. The main purpose of this is not food safety, but to kill yeast cells, which prevents fermentation and delays natural crystallization. This extensive processing also removes air bubbles, giving the honey a perfectly clear, smooth, and liquid appearance.

Reasons for pasteurising honey include:

  • Aesthetics: A clear, uniform appearance is often preferred by consumers.
  • Shelf life: The process slows down crystallization, allowing the honey to stay liquid for much longer periods on supermarket shelves.
  • Convenience: The smooth, runny texture is ideal for easy pouring, particularly in squeeze bottles.

The fundamental difference: Processing and its effects

The fundamental distinction lies in the processing method. Raw honey's minimal treatment preserves its natural state, while pasteurised honey's intensive heat and filtration fundamentally alter its composition. The heating process denatures or destroys key enzymes like glucose oxidase, which gives honey its antibacterial properties. Similarly, the delicate phytonutrients, including polyphenols and flavonoids that act as antioxidants, are reduced. Ultra-filtration removes all traces of bee pollen and propolis, which are rich in health-boosting compounds.

Feature Raw Honey Pasteurised Honey
Processing Minimally heated (if at all) and lightly strained. Heated to high temperatures (63-77°C) and often ultra-filtered.
Nutritional Value High in antioxidants, enzymes, pollen, and propolis. Significantly reduced nutritional content due to heat and filtration.
Appearance Cloudy, opaque, or creamy with visible particles. Perfectly clear, translucent, and consistently smooth.
Crystallization Crystallizes more quickly and naturally over time. Stays liquid for longer periods due to heat-dissolved crystals.
Flavour Profile Rich, complex, and distinct, varying by floral source. Milder, less complex flavour due to heat damage.
Storage Life May ferment if moisture content is high; best stored properly. Longer shelf life and less prone to fermentation.

The role of natural compounds

Raw honey is revered for containing a host of natural compounds that are either eliminated or reduced in pasteurised honey. Bee pollen, for instance, contains a variety of antioxidants, amino acids, and vitamins, with studies indicating potential anti-inflammatory and antibacterial effects. Similarly, bee propolis, a resinous substance used by bees to build their hives, is also present in raw honey and has shown promising anti-cancer and anti-ulcer properties in some studies. The presence of these compounds is often tied to the perceived health benefits of raw honey.

Conversely, the aggressive heating and filtration of pasteurised honey remove these beneficial elements. While this creates a product with a more predictable and uniform appearance and texture, it comes at the cost of its natural vitality. Some commercial products labelled simply as “honey” may even contain added sweeteners like high fructose corn syrup, further diminishing their nutritional value. Always read labels carefully to avoid unintentionally consuming an adulterated product.

Making your choice

Ultimately, the choice between raw and pasteurised honey depends on your priorities. If you are seeking the maximum health benefits, the complex flavour profiles, and the most natural form of the product, raw honey is the clear winner. Its natural cloudiness and tendency to crystallize are simply signs of its purity and minimal processing. If a smooth, clear, and convenient-to-pour sweetener with a long shelf life is what you need, pasteurised honey is the more practical option. However, be aware that you will be sacrificing much of the honey's natural goodness for appearance and consistency.

In conclusion, the primary difference that separates these two types of honey is the processing. Raw honey is a product of minimal intervention, preserving its rich nutritional profile and complex character. Pasteurised honey, a product of modern industrial processing, prioritizes aesthetic uniformity and shelf stability over natural integrity. Understanding this distinction empowers consumers to make an informed choice that aligns with their health goals and culinary preferences.

Frequently Asked Questions

Many believe raw honey is healthier because it contains more antioxidants, enzymes, and other beneficial compounds that are lost during the high-heat pasteurisation process. However, more research is needed to definitively compare their health impacts.

Pasteurisation heats the honey to dissolve any existing sugar crystals. This process delays future crystallization, giving the honey a longer shelf life and maintaining a clear, liquid state.

Crystallization is a natural process where honey's glucose separates from the water, forming solid crystals. It is not a sign of spoilage, but rather an indication that the honey has not been heavily processed.

People with severe pollen allergies should be cautious with raw honey, as it contains trace amounts of bee pollen. It is best to consult a doctor or allergist before consuming it.

No, honey is not safe for infants under 12 months old. It contains spores of Clostridium botulinum which can cause infant botulism, and pasteurisation does not remove this risk.

Yes. Raw honey is typically cloudy and opaque, while pasteurised honey is usually perfectly clear and translucent due to extensive heating and filtration.

Yes, if you heat raw honey at high temperatures, you can destroy or reduce its beneficial enzymes and antioxidants. To reliquefy crystallized honey, it is best to use a warm water bath rather than high heat.
