What is the shelf life of xanthan gum?

The shelf life of xanthan gum is typically around 2 years when stored in a cool, dry place away from direct sunlight. However, the exact shelf life may vary depending on the specific product and storage conditions. It's always best to check the manufacturer's recommendations for the specific xanthan gum product you are using.

Here are some additional factors that can affect the shelf life of xanthan gum:

1. Temperature: Xanthan gum is sensitive to heat, so it's important to store it in a cool place. Temperatures above 120°F (50°C) can shorten the shelf life of xanthan gum.

2. Humidity: Xanthan gum can absorb moisture from the air, so it's important to store it in a dry place. High humidity levels can cause xanthan gum to clump or lose its effectiveness.

3. Exposure to light: Xanthan gum is sensitive to light, so it's important to store it in a dark place or opaque container. Exposure to light can cause xanthan gum to discolor or lose its effectiveness.

4. Packaging: Xanthan gum should be stored in an airtight container to prevent exposure to air and moisture.

If you notice any changes in the appearance, smell, or taste of xanthan gum, it's best to discard it and purchase a new one.
