Quick Answer
Yes, you can store nuts in Mylar bags without spoiling, but proper technique and conditions are crucial to prevent degradation.
Mylar Bag Storage Basics
Mylar bags are an excellent option for long-term food storage due to their durability, moisture barrier, and ability to prevent light penetration. To store nuts in Mylar bags, start by selecting a high-quality Mylar bag that is specifically designed for food storage and is at least 3-5 mils thick to prevent pinholes.
Preparing the Nuts for Storage
Before storing nuts in Mylar bags, make sure they are properly dried and cooled to around 1% moisture content to prevent moisture-related spoilage. This can be achieved by spreading the nuts out in a single layer on a clean surface or using a food dehydrator. Store the dried nuts in an airtight container for a few days to allow any remaining moisture to evaporate.
Sealing and Storing the Mylar Bags
To seal the Mylar bags, use a food-grade vacuum sealer or a manual sealer. Make sure the seal is tight and there are no gaps or holes that could allow air or moisture to enter. Store the sealed Mylar bags in a cool, dark place with a consistent temperature between 40°F to 60°F (4°C to 15°C) to maintain the nuts’ quality and shelf life.
