What is that white greasy substance you sometimes get on hot dogs or bologna?

That white greasy substance you sometimes see on hot dogs and bologna is called fat or fat crystals. It's a natural part of the meat and is perfectly safe to eat.

Here's why it forms:

* Fat Composition: Meat contains different types of fat, including saturated and unsaturated fats.

* Cooling & Storage: When the meat cools down, some of the fat molecules solidify and form crystals. This is especially noticeable in processed meats like hot dogs and bologna.

* Water Content: The water content in the meat can also influence the appearance of fat crystals. A higher water content can make them more visible.

Don't worry about it! Fat crystals are just a sign of the meat's natural composition and don't affect its safety or flavor. They can be easily removed by wiping them off before eating.

It's important to note that some people may prefer hot dogs and bologna without visible fat crystals, so you might find them "re-worked" to reduce this appearance.
