The best way to store homemade flaxseed oil is in the refrigerator.
Storing flaxseed oil, also known as linseed oil, at a low temperature significantly helps in maintaining its freshness and quality. This is crucial because flaxseed oil is highly susceptible to oxidation, which can cause it to go rancid quickly.
Why Refrigeration is Key
According to the reference, the fridge is the best place to store linseed. Just like storing freshly ground coffee in the fridge or freezer helps preserve its quality, the low temperature keeps opened linseed (flax) oil a bit fresher for a bit longer. The cold environment slows down the chemical reactions that degrade the oil, extending its shelf life.
Best Practices for Storing Homemade Flaxseed Oil
Beyond just temperature, consider these additional factors to maximize the lifespan and quality of your homemade flaxseed oil:
- Use an Airtight Container: Ensure the oil is stored in a container with a tightly sealing lid to prevent exposure to air, which contributes to oxidation. Dark glass bottles are often preferred as they also help block light.
- Minimize Air Exposure: Fill the container as much as possible to reduce the amount of air inside.
- Store Away from Light: Light, especially UV light, can also degrade the oil. Store the oil in an opaque container or keep it in a dark place within the fridge.
- Use Quickly: Even with proper storage, flaxseed oil has a limited shelf life once opened. Aim to use homemade oil within a few weeks to ensure optimal freshness and nutritional value.
Following these steps, particularly keeping the oil refrigerated as recommended, will help preserve your homemade flaxseed oil.
