Sugar, a pantry staple, is susceptible to various factors that can affect its quality and shelf life. While granulated sugar itself doesn’t technically “expire” in the same way other foods do, it can undergo changes that make it less desirable for use. Moisture absorption, clumping, and even pest infestation can compromise its texture and usability. Proper storage is key to maintaining sugar’s quality and preventing these issues, ensuring it remains readily available for all your culinary needs.
Mylar bags, combined with oxygen absorbers, offer a superior method for long-term sugar storage. These specialized bags create a robust barrier against the elements that can degrade sugar, providing an ideal environment for preserving its quality for extended periods.
This blog post will delve into the factors influencing sugar’s shelf life and explore how Mylar bags and proper storage techniques can help you keep your sugar fresh and usable for years to come.
Can You Store Sugar in Mylar Bags

Yes, you absolutely can store sugar in Mylar bags, and it’s a highly recommended method for extending its shelf life. Mylar bags offer superior protection against the elements that can degrade sugar, such as moisture, pests, and oxygen. These bags create a strong barrier that helps prevent sugar from clumping, absorbing odors, or becoming infested, ensuring it remains usable for an extended period.
The key to effectively storing sugar in Mylar bags is the inclusion of oxygen absorbers. While sugar itself doesn’t necessarily “go bad” in the same way as other foods, it can become hard and unusable due to moisture absorption or pest activity. Oxygen absorbers create an oxygen-free environment within the Mylar bag, preventing these issues and preserving the sugar’s texture and quality. This combination of Mylar bags and oxygen absorbers is ideal for long-term sugar storage.
Storing sugar in Mylar bags is a simple yet effective way to ensure you have a readily available supply of this essential ingredient. Whether you’re stocking up for emergencies, preserving bulk purchases, or simply want to keep your sugar fresh for everyday use, Mylar bags provide a reliable solution for long-term sugar storage. Following proper sealing and storage guidelines will help you maintain the quality of your sugar for years to come.
How Long Will Sugar Last in Mylar Bags

Sugar, unlike many other food items, has an incredibly long shelf life, especially when stored properly. In fact, granulated white sugar can essentially last indefinitely if kept dry and away from pests.
When stored in Mylar bags, sugar’s longevity is further enhanced. Mylar bags provide a superior barrier against moisture, oxygen, and pests, which can cause sugar to clump or become contaminated. By sealing sugar in Mylar bags, you’re essentially creating a protective environment that helps maintain its quality for many years.
While it’s difficult to give an exact timeframe for how long sugar will last in Mylar bags, it’s safe to say that it will remain good for many years, potentially even decades, as long as the bags are properly sealed and stored in a cool, dry place.
Here are a few key points to remember:
- No oxygen absorbers needed: Unlike many other foods, sugar does not require oxygen absorbers in Mylar bags. In fact, they can actually cause the sugar to clump.
- Keep it dry: Moisture is the main enemy of sugar. Ensure your sugar is dry before storing it in Mylar bags, and store the bags in a dry location.
- Proper sealing is crucial: A good seal is essential to prevent moisture and pests from entering the bag.
With proper storage in Mylar bags, you can ensure your sugar remains fresh and usable for all your cooking and baking needs for many years to come.
How to Store Brown Sugar in Mylar Bags

Storing brown sugar in Mylar bags is a good way to keep it fresh for longer, but there are a few key differences from storing granulated white sugar.
Here’s a guide:
1. Preparation:
- Choose the right bags: Use food-grade Mylar bags. 4 mil thickness is a good choice.
- No oxygen absorbers: Unlike white sugar, brown sugar does not need oxygen absorbers. They can actually cause it to clump.
- Consider smaller bags: Brown sugar tends to dry out and harden when exposed to air. Using smaller bags can minimize the amount exposed each time you open one.
- Have a plan for softening: Even with the best storage, brown sugar can sometimes harden. Have a plan for softening it when needed (see tips below).
2. Filling the Mylar Bag:
- Pack it well: Brown sugar should be packed firmly to minimize air pockets.
- Don’t overfill: Leave a little headspace for sealing.
3. Sealing the Mylar Bag:
- Seal tightly: Use a heat sealer for the best seal. An iron can work, but it’s less reliable for an airtight seal.
- Remove as much air as possible: Before sealing, gently press out as much air as you can from the bag to help prevent drying.
4. Storage:
- Cool, dark place: Store in a cool, dark, and dry location.
- Airtight container: For extra protection, you can place the sealed Mylar bags inside an airtight container.
Tips for softening brown sugar:
- Moist towel: Place a damp paper towel in the container with the hardened brown sugar. Seal it up and let it sit overnight.
- Apple slices: Similar to the towel method, apple slices can add moisture.
- Microwave: Microwave the brown sugar in short bursts (20-30 seconds) until it softens. Be careful not to overheat it.
Important Note: Brown sugar has a shorter shelf life than white sugar due to the molasses content. Even with proper storage, it may not last indefinitely. However, Mylar bags can significantly extend its freshness and prevent it from drying out too quickly.
Conclusion
In conclusion, storing sugar in Mylar bags with oxygen absorbers offers a significant advantage for long-term preservation. By protecting sugar from moisture, pests, and oxygen, Mylar bags help maintain its quality and prevent clumping or other undesirable changes for extended periods. While proper storage conditions are important, the barrier provided by Mylar bags is key to maximizing sugar’s shelf life.
