Red juice in packaged meat and rare meat is not as scary as you think.

When we buy packaged red meat (pork, beef...) in the supermarket, we often see red liquid at the bottom of the box. When we cook rare meat, we also see red liquid coming out.

Many people think it is animal blood, so they feel scared when eating it. However, according to Buzzfeed, the red liquid is actually a protein called myoglobin. Protein is the substance that gives red color to meat and meat juices, so it is completely normal for it to accumulate under the packaging.

Similar to hemoglobin found in human blood, myoglobin carries oxygen to animal muscles. The protein changes color when exposed to air and heat, which is why meat turns from red to brown when it's been cooked or left in packaging for too long, according to the New York Times.

The red liquid that seeps from raw meat isn’t blood, either. According to The Huffington Post, the liquid is actually a protein found at the bottom of the packaging.

Grilled meats and meats in sandwiches are not exposed to air and therefore retain more red myoglobin. So next time you come across a piece of meat with red juice, don't be afraid, enjoy it, it's just protein.
