Yes, you can keep rice water outside of the refrigerator, but only for a very limited time due to its short shelf life.
According to expert advice, unlike commercial products that contain preservatives, homemade rice water has a brief expiration window. It's advised to use rice water within 24 to 48 hours when stored at room temperature. Storing it longer outside of refrigeration significantly increases the risk of bacterial growth.
Why the Short Shelf Life?
Rice water is a natural product without added preservatives. This makes it susceptible to bacterial growth, especially in warmer conditions like room temperature. The nutrients and starches in the water act as a food source for microbes.
- Room Temperature Storage: Use within 24 to 48 hours.
- Refrigerated Storage: Can last up to 5 to 7 days.
Using old or expired rice water can introduce harmful bacteria to your skin or hair, potentially causing irritation or other issues.
Practical Tips for Storing Rice Water Outside
If you need to store rice water at room temperature for a short period (under 48 hours):
- Use a Clean Container: Store it in a clean, airtight glass jar or container.
- Keep it Cool and Dark: Place the container in a cool, dark spot away from direct sunlight or heat sources.
- Observe for Spoilage: Before use, check for signs of spoilage like a foul odor, cloudy appearance, or mold. If any are present, discard it immediately.
- Smaller Batches: Consider making smaller batches if you don't plan to use it all within 24-48 hours to avoid waste.
While convenient for immediate use, prolonged storage of rice water outside the refrigerator is not recommended due to the rapid potential for bacterial contamination. For best results and safety, refrigeration is the preferred storage method for extending its usability up to a week.
