How to know if gochujang is bad?

So how will you know if your gochujang is still safe to eat? Here are the signs of spoilage you should watch out for:

1. Sour smell

A weird smell is one of the surefire ways to tell if your gochujang has gone bad. It’s hard to describe what it smells like. But it definitely shouldn’t smell sour. If your paste smells like vinegar, discard the tub right away.

2. Color change

Fresh gochujang looks bright red, almost like crimson. So if it turned a darker red, don’t panic. Due to oxidation, it’s normal for the paste to change a bit in color – as long as it’s still a shade of red.

You can just scrape the top layer off to remove the oxidized portions.

But if you’re seeing tints of green, white, yellow, or other non-red colors on your paste, watch out! That’s definitely a telltale sign that it’s time to say goodbye to your gochujang.

3. Sour or bitter taste

Still unsure after smelling and inspecting your tub? Try tasting a teeny bit of the paste.

It’s also normal for gochujang taste to get stronger with time. That’s because it continued to ferment as it sat in your cupboard or fridge.

But it should never taste bitter or sour. Don’t hesitate to discard your tub if you catch a bit of sourness or bitterness in your paste.

4. Mold

Notice white bumps on the surface of your paste? That’s likely mold.

Like in any other food, mold is a dead giveaway for spoilage. If you see this on your paste, bid farewell to the entire tub right away. And no, scraping the mold off to keep the unaffected parts won’t help.

5. Runny texture

Fresh gochujang feels like sticky cooked glutinous rice. That means that the paste should be viscous and firm. If it looks runny or slimy, throw it away.

An old technique to check your paste’s consistency is by sticking a spoon through it. If the spoon stands, you’re likely good to go. But if the spoon falls, then it’s best to avoid using your paste.

6. Oil on the top layer

You should also watch out if oil has started to float on your gochujang’s surface. This is caused by the fermented beans in the paste. If you see this on your paste, we highly suggest discarding your tub.

Some will say that it’s still okay to use it like this. But still, best to keep safe since the tummy ache isn’t worth it!

7. Allergies and stomach aches

Ate an old gochujang that you suspect has gone bad? If you experienced allergies and stomach aches, your gut instinct might be right. That tub is likely spoiled.

That’s especially true if you’re not allergic to gochujang’s ingredients. So if you’re feeling a bit itchy or sick after your bibimbap, that expired gochujang is likely the culprit.

So how do you store your gochujang properly to avoid spoilage?

The number one killer of gochujang pastes is heat. That’s why for unopened tubs, you should store it in a cool, dark place. Your closed cupboard or pantry should be ideal.

For used gochujang, it’s best to keep it refrigerated. And notice the plastic layer beneath the lid? Most Korean locals advise you to leave this cover on when you open the tub. In this way, the tub holds moisture better so that the paste doesn’t dry up.

Some even recommend covering your paste’s top layer with plastic wrap for added seal. You can also transfer your paste to an airtight container.
