Does Manuka Honey Expire? The Truth About Liquid Gold
Just discovered a jar of Manuka honey at the bottom of your cupboard. It's a bit different, perhaps it's darker than what you remember or maybe it's become a hard chunk of sugary, sweet. You've paid a premium price for this high-end product, and now you're pondering whether it's safe to consume or should it go in the garbage?
It's a frequent issue. We're conditioned to look for the expiration dates of everything from food items to milk and assume that anything beyond the "best before" date is headed for the garbage. However, honey-particularly top-quality Manuka honey--plays by a completely different system of regulations. Archaeologists have found honey jars in the old Egyptian tombs that have been uncovered for thousands of years, and, most importantly, are edible.
While your pantry may not be a pyramid, the research safeguarding the honey of the past applies to your jar, too.
In this article, we will look at the length of time Manuka honey can last, as well as how it is able to sustain its amazing endurance, and how to identify the signs that it's time to dispose of it. We will also go over appropriate storage methods to ensure that your precious gold remains in top condition for many years to come.
The quick answer is Is Manuka honey last?
Technically, no. Pure and properly stored Manuka honey doesn't really have a time limit in the sense of traditional expiration. It is among the few food items around the globe that can be stored for a long time without deteriorating.
But, you'll likely find the "Best Before" date printed on the label. It is not an expiration date for safety; instead, it's the manufacturer's guarantee of how long the honey will maintain its highest quality texture, texture, and distinctive bioactive characteristics. Over time, all honey undergoes natural changes. It might darken in colour or lose some of its aroma or flavour, or crystallise. These changes may alter the taste, but they do not make honey intoxicating to consume.
It is noted that the National Honey Board states that although honey can be stable for years or even centuries inside sealed containers, shelf life is typically specified as 2 years for quality assurance reasons. Therefore, even though honey can last longer than you, it's at its peak within the manufacturer's timeframe.
What is the reason? Manuka honey lasts for a lifetime (almost)
The secret behind Manuka honey's long-lasting shelf life is in its distinctive chemical composition. Bees are master chemists, creating a material that is naturally averse to spoilage and bacteria.
Low moisture content
Bacteria love moisture. It is crucial for their survival as well as reproduction. Honey is hygroscopic. This means that it is low in water, typically less than 20% as per international standards such as those of the Codex Alimentarius. When honey is produced, bees fly to evaporate the excess water from nectar, which thickens it to form the syrup we recognise. The absence of water causes bacteria to dehydrate, making it almost impossible for the bacteria to reproduce.
Acidity
Manuka honey has a naturally acidic pH is usually ranges somewhere between 3.4 to 6.1. The acidic environment is corrosive enough to stop the growth of a variety of commonly found spoilage microorganisms, thereby keeping honey from going bad.
Antibacterial properties
Even though all honeys contain tiny quantities of hydrogen peroxide (a natural antiseptic), Manuka honey contains an additional non-peroxide component that comes from its Manuka flowers (Leptospermum Scoparium). This particular property is strong and stable, adding to the honey's reputation as a source of health and longevity.
The changes you may see can be seen in the course of time.
The fact that honey is safe for consumption does not mean that it will never alter. Honey can be a live biological product, and over time, it will alter its appearance and even its texture. This is how it is normally:
Crystallisation
If your golden, silky smooth syrup becomes a rough chunk of solid, be concerned. The process of crystallisation (or"granulation") is a natural process that indicates that honey is natural and unpasteurised.
Honey is an extremely saturated sugar solution comprised of fructose and glucose.
In time, glucose is separated from water and creates crystals. Manuka honey is thin and thixotropic (meaning it is more fluid when stirred or shaken, and more dense when it is standing) and is able to develop an unusual jelly-like texture or crystallise into a rough texture.
What can you do to fix it? You can reverse crystallisation easily.
Place the honey jar in a bowl filled with mild drinking water (not hot) and stir it gently until the crystals break down. Avoid making use of the microwave, since high temperatures can damage the beneficial enzymes and delicate flavour compounds.
Darkening colour
It is typical to see Manuka honey's colour change as it the passage of time passes. It is usually caused by the Maillard reaction, which is a chemical reaction that occurs between amino acids with the reduction of sugars. It can also be due to temperature fluctuations when it is stored. A darker shade doesn't mean that the honey is rotten; however, some experts believe that aged honey has more richer and diverse flavour and taste.
HMF levels
Hydroxymethylfurfural (HMF) is an organic compound that naturally forms in honey over time or when it is heated. It is commonly used to determine the quality and freshness of storage. International standards typically demand HMF to be less than 40 mg/kg (or 80 mg/kg in the case of honey from the tropical regions).
Although you aren't able to examine HMF in your home environment, keeping the honey in a cooler area can slow down the process of formation and preserve the quality of the honey for a longer time.
What is the best time to throw Manuka honey out?
Although rare, honey will likely go bad in the event of improper handling or improperly. These are indicators that the honey you have purchased is no longer safe to consume:
Fermentation
When the amount of moisture in honey exceeds 20%--usually because of improper extraction or taking the lid off in a moist room, yeast could endure and trigger fermentation.
-
The smell of fermented honey is like bread dough rising or alcohol.
-
The appearance: You could observe bubbles growing inside the honey, or they may expand and spill out from the container.
-
The taste: It'll include a sharp, sour flavour rather than a smooth sweetness.
Visible mold
Due to its antibacterial and antimicrobial properties, mould growth on honey is very rare. However, if liquids or debris from food (like toast crumbles or butter from a knife that has been soiled) enter the jar, mould can develop over the top. If you spot a lot of fuzz or patches of colouration, then you should throw out the entire container to avoid any risk.
Contamination
If the honey is stored in a metal container that is not food-grade, the acidity of the honey may corrode the steel over the course of time, causing it to leach into the food. Make sure to store your honey in food-grade plastic or glass containers.
How do you keep Manuka honey to prolong its life?
To make sure your money lasts the longest can make sure you follow these easy storage guidelines:
-
Make sure it is cool. The heat is the main adversary of honey. Keep your jar in a cool cupboard or pantry, at least away from ovens or stoves. The ideal temperature range is between 10 and 20 °C.
-
Make sure it is dark. Long-term exposure to sunlight can directly reduce the bioactive components found in Manuka honey. Jars that are opaque or amber are commonly used to protect the contents; however, keeping them in the cupboard is your best option.
-
Make sure it is sealed tightly: Honey absorbs moisture from the air, much like sponges. Be sure to seal the lid securely following each use to avoid fermentation.
-
Avoid refrigeration: Although the honey won't be affected by refrigeration but it can accelerate the crystallisation, making it difficult to spread. The pantry is good.
Frequently Asked Questions
Can I take a bite of Manuka honey following the "Best Before" date?
Yes, provided that it is stored properly and doesn't show any indications of fermentation (sour smell and bubbles). The date serves as a benchmark for quality, not for safety.
Does Manuka honey decrease its potency with time?
Although Manuka honey is extremely stable, the bioactive components that give it its distinctive properties may be degraded slowly when exposed to extreme heat or sunlight over several years. To reap the most health benefits, it's best to use the honey within its suggested period of time.
What is the reason my Manuka honey is dissolving?
Separation into the top layer of liquid as well as a solid layer at the bottom is simply a method of crystallisation. It's completely safe. It is possible to stir it around for a few seconds to combine the layers together, or gently warm it to melt the layer below.
Can crystallised honey be eaten safely? Consume?
Absolutely. Crystallised honey is healthy and safe in the same way as liquid honey. Some like the crunchiness on toast or with tea.
Conclusion
Manuka honey is an amazing organic product that has a shelf life that is comparable to any other food you have in your kitchen. Due to its low acidity, moisture and bioactive qualities that are unique, it's food-safe for many years, or even years.
Before you throw away the crystallised jar, you should take an extra look. A warm bath could be just what it takes to restore its original beauty. By keeping it in a dark, cool location and ensuring that the lid is tightly shut, you can relish all the sips of golden liquid no matter how long it takes to reach the very bottom of your container.
