Ever sliced into a perfectly cooked steak only to watch a red liquid seep out and thought, “Wow, that’s a lot of blood”?
Let’s set the record straight: that’s not blood. It’s myoglobin. And if you’re squeamish about it, you really shouldn’t be, because it’s a sign of flavour, freshness, and proper ageing.
At Biltong Chief, where premium cuts meet real carnivore cravings, we think it’s time this juicy myth got a proper grilling. So fire up your appetite, we’re diving into meat science with a side of tasty truth.
TL;DR (Too Long, Deliciously Read):
- That red stuff in your steak? Not blood. It’s myoglobin.
- It’s completely safe, natural, and a sign of freshness and flavour.
- Darker, “juicier” cuts have more myoglobin due to muscle usage.
- Biltong has less visible myoglobin but keeps the nutrients and taste.
What Is Myoglobin?
Myoglobin is a protein found in muscle tissue, responsible for storing oxygen in muscle cells. When exposed to air, myoglobin takes on that rich reddish colour, which is exactly what you’re seeing in your steak. It’s totally harmless, natural, and packed with flavour.
Here’s the breakdown:
- Myoglobin ≠ blood.
- It’s a water-soluble protein found in meat, not a sign of undercooking.
- The red liquid is a mix of myoglobin and water, not gore.
Why People Think It’s Blood
It’s an understandable mistake. That red, juicy drip looks a lot like blood. But by the time meat reaches your plate, it’s long been bled during processing.
What remains is just muscle juice, and it’s a good thing.
This rich liquid:
- Keeps your steak juicy and tender
- Indicates a fresh, oxygen-rich cut
- Is a natural part of meat, not something to fear
The Myoglobin Myth Busted
Different cuts of meat have different myoglobin levels. That’s why:
- Ribeye and hanger steak often look darker and “juicier”
- Fillet and tenderloin appear lighter and drip less
The more a muscle worked during the animal’s life, the more myoglobin it developed.
That darker meat? It’s rich, full-bodied and full of character.
Cooking and Myoglobin: What You Should Know
When you cook steak, myoglobin changes colour with heat:
- Rare: bright red centre
- Medium: pink and juicy
- Well-done: brown, less juicy
So that “bleeding steak” you see on Instagram? That’s just perfectly cooked rare beef, not a horror show. We’re all for it.
Myoglobin in Biltong?
When it comes to biltong, things are a little different.
Biltong is air-dried, meaning the moisture, and most visible myoglobin, is drawn out over time. But the nutrients remain. Myoglobin is rich in iron and still contributes to biltong’s deep, beefy flavour.
So whether you like your beef fresh off the grill or perfectly dried and spiced, myoglobin is still doing its thing — delivering the taste you crave.
