What Exactly Is Powdered Citric Acid?

Powdered citric acid is an organic acid derived from citrus fruits like lemons, limes, and oranges. It’s commonly used as a natural preservative, souring agent, and flavor enhancer in food and beverages. Unlike lemon juice, which contains pulp and water, powdered citric acid is pure acid – meaning it’s more potent and easier to measure for recipes or DIY projects.

How to Store Citric Acid Like a Pro

Proper storage is key to keeping your citric acid effective and ready for action. Here are some top tips:

• Airtight Container: Always store in a sealed container to prevent moisture absorption.
• Cool, Dry Place: Avoid humid areas like under the sink; instead, go for a cool pantry or cabinet.
• Away from Light: UV exposure can degrade its potency over time, so opaque containers are ideal.
• Label Clearly: Don’t let it blend into the background – label your jar clearly so it doesn’t accidentally become part of your salt collection!
