How to Store Sour Cream?

The food quality and handling of sour cream are affected by its expiration date. There is a specific way you’re supposed to store sour cream in the fridge to avoid spoilage.

Milk is prone to bacteria, fungus, and mold. The proteins and sugars in milk pave the way for a host of good and bad bacteria in sour cream. The good bacteria keep the sour cream fresh-smelling and stomach-friendly. But the bad bacteria is what causes the sour cream to spoil easily.

Factors like temperature, exposure to air, or moisture can speed up the spoilage. If you keep sour cream at room temperature, it will spoil quicker. So make sure you keep the sour cream in the fridge as soon as you buy it. And that it’s kept away air and moisture particles at all times.

When you keep sour cream in the fridge, make sure it’s not out in the open. A fridge is something that everybody in the household uses multiple times per day. So the constant opening and closing of the fridge door can cause temperature fluctuations.

When you keep sour cream in the front, it, too, is exposed to these fluctuations. This may affect the freshness of the food.

To avoid this, keep the sour cream somewhere at the back or at the bottom of the shelves.
