How to Tell if Chocolate is Bad

In the grand panorama of life's delights, indulging in a bar of fine chocolate is a simple yet delicious pleasure.

But what happens when you stumble upon an old bar lurking at the back of the cupboard?

How do you tell if it's still fit for consumption or if it's time to bid it a sad farewell?

In this post, we'll guide you through the telltale signs to determine if your chocolate has gone off, from changes in appearance and texture to a different smell or taste.

So, read on, and let's ensure that your next chocolate indulgence is as deliciously satisfying as it ought to be.

How To Know If Chocolate Is Bad

While chocolate doesn't spoil in a traditional sense, it may still lose its quality over time.

Indications that the chocolate may not be in its prime include an altered appearance, which could present as a dull, greyish hue or white streaks known as 'chocolate bloom.'

These changes, usually triggered by temperature fluctuations, might affect the texture and taste but don't make the chocolate unsafe.

Another sign of ageing could be a brittle texture without the typical snap when broken.

In terms of smell, any disappearance of the rich chocolate aroma or the presence of an unusual scent suggests that the chocolate may have aged.

Finally, if the chocolate tastes stale or off, it would be advisable to avoid consuming it.

What Does Gone Off Chocolate Look Like?

Chocolate that has "gone off" or deteriorated in quality won't necessarily look like food that has spoiled in the traditional sense.

It's important to know that chocolate doesn't become unsafe to eat over time unless foreign contaminants are introduced.

However, the quality and taste can be affected. Here are a few signs to look for:

  1. Chocolate Bloom: This is a common sign that chocolate has been exposed to fluctuating temperatures or has been stored for a long time. It appears as a whitish or greyish coating on the surface of the chocolate. There are two types: fat bloom, caused by changes in the fat crystals in the chocolate, and sugar bloom, caused by surface moisture that dissolves the sugar. While this doesn't mean the chocolate is spoiled, it can affect the texture, making it grainy.

  2. Discolouration: Beyond blooming, any other discolouration or spots on your chocolate might indicate that it's past its best.

  3. Odour: While this isn't something you can see, the smell of the chocolate can be a telling sign. If it lacks the usual rich chocolatey aroma or smells unusual, it might not be at its best.

Remember, always store your chocolate in a cool, dry place, ideally between 18-20 degrees Celsius, away from strong odours, and it should maintain its quality for some time.

What is Chocolate Blooming?

Chocolate blooming refers to the whitish or greyish coating that can appear on the surface of chocolate.

This doesn't mean the chocolate is bad or unsafe to eat, but it does indicate that the chocolate has undergone a change in its structure or has been affected by its environment.

There are two types of chocolate bloom:

  1. Fat Bloom: This occurs when the fat (cocoa butter) in the chocolate separates and rises to the surface, usually because of warm storage temperatures or significant temperature fluctuations. This causes the chocolate to have a somewhat greasy feel and it can make the texture crumbly or grainy.

  2. Sugar Bloom: This happens when the sugar in the chocolate dissolves in moisture -- say, from being stored in a damp area or being kept in the fridge -- and then recrystallises on the surface of the chocolate as it dries. Sugar bloom gives the chocolate a rough, grainy texture and dull appearance.

Both types of bloom can affect the texture and taste of the chocolate, though it remains safe to eat.

Prevent blooming by storing chocolate properly: keep it in a cool, dry place away from sunlight and strong odours, at a steady temperature of around 18-20 degrees Celsius.

How Should You Store Chocolate to Prevent it From Spoiling?

​​Storing chocolate correctly can help preserve its quality and prevent issues like chocolate blooming.

Here are some top tips for keeping your chocolate at its best:

  1. Temperature: The ideal storage temperature for chocolate is between 18-20 degrees Celsius. Temperatures higher than this can cause the chocolate to melt, leading to fat bloom when it solidifies again.

  2. Humidity: Keep chocolate in a dry place, as moisture can lead to sugar bloom. The humidity level should ideally be less than 50%.

  3. Light: Direct sunlight or artificial light can heat up the chocolate and degrade its quality. Store it in a dark place.

  4. Odours: Chocolate can absorb the flavours of strong-smelling foods, so keep it in an odour-free area. To prevent this, you might want to keep the chocolate wrapped or in a sealed container.

  5. Refrigeration: It's generally best not to store chocolate in the fridge, as the humidity can cause sugar bloom. However, if you live in a hot climate and have no choice but to refrigerate your chocolate, put it in an airtight container, and when taking it out, let it come back to room temperature before unwrapping. This minimises condensation forming on the chocolate, which can also lead to sugar bloom.

Remember, these storage guidelines aim to keep chocolate flavour and texture at their peak.

Chocolate doesn't typically 'spoil' in the way that dairy or meat does, but its taste and texture can degrade over time if not stored properly.

Final Notes On How To Know If Chocolate Has Gone Bad

When assessing whether chocolate has gone bad, several factors come into play.

Check for changes in appearance, such as dullness, discolouration, or white streaks known as chocolate bloom.

This might not be harmful but can affect the taste and texture.

Also, consider the texture itself; a brittle or grainy feel might indicate it's past its best.

Moreover, chocolate's aromatic scent should remain rich; an off smell can signal quality degradation.

Lastly, pay attention to any alteration in taste, such as a stale or off flavour.

The "best before" date on the packaging provides guidance, and proper storage in cool, dry conditions helps preserve the chocolate's quality longer.

Although chocolate doesn't spoil like some foods, its taste and texture can change over time.

Trust your senses when uncertain.

After all, the enjoyment of chocolate is best when it's fresh, especially if it's Whitakers!
