What is the point of that little bit paper they put in tubs butter?

The little bit of paper in tubs of butter is called parchment paper. It serves several important purposes:

Preventing Sticking: Parchment paper acts as a barrier between the butter and the lid or packaging of the tub. This helps prevent the butter from sticking to the container, making it easier to remove and spread.

Retaining Freshness: Parchment paper helps preserve the freshness of butter by preventing air from entering the tub. This slows down the oxidation process and keeps the butter from absorbing unwanted flavors or aromas.

Moisture Control: Parchment paper absorbs excess moisture from the butter, preventing it from becoming soggy or spoiled. This helps maintain the butter's consistency and texture.

Easy Spreading: Parchment paper makes it easier to spread butter on bread or other foods. When you remove the paper, it creates a smooth surface on the butter that allows for even spreading without tearing.

It's important to note that parchment paper is food-safe and does not pose any health risks when consumed. It can be safely left in the tub of butter and does not need to be removed before use.
