Always keep the container sealed tightly, even in the fridge or freezer, to prevent any exposure to air. Using smaller containers for daily use can minimize repeated exposure to the whole batch.
Risks of Improper Storage
Improper storage can lead to flax protein becoming rancid, developing an off-putting smell or bitter taste. Leaving the container open or storing it in a warm, light-filled place can accelerate spoilage.
Temperature fluctuations can further this process, so keeping the flax protein in a consistent, cool environment is best. Ignoring proper storage can result in a loss of the nutritional benefits of flax protein.
Handling and Processing Flax
Proper handling and processing of flax ensures that its nutritional benefits are preserved while minimizing spoilage risks. Whether converting whole flaxseeds to ground flaxseed or understanding commercial processing, each step is crucial.
From Whole to Ground
To optimize nutrient availability, many choose to grind whole flaxseeds. Whole flaxseeds have a hard outer shell, making it difficult for the body to access the nutrients inside. Ground flaxseed provides easier access to omega-3 fatty acids, fiber, and lignans.
A coffee grinder, blender, or specialized flax mill can be used for grinding. Ground flaxseed can be used in flaxseed eggs or as an addition to smoothies. Performing this process in small batches and storing the ground seeds in an airtight container helps maintain freshness.
Homemade Flaxseed Meal
Making homemade flaxseed meal is a simple and effective way to ensure freshness. Start with whole flaxseeds, preferably golden or brown depending on preference. Use a high-speed blender or food processor to pulverize the seeds until they form a fine meal.
Freshly ground flaxseed should be stored in a cool, dark place, ideally in the refrigerator. This minimizes exposure to light, heat, and oxygen, which accelerates spoilage. Always use an airtight container to prevent moisture and contaminants from affecting the quality.
Commercial Processing Differences
Commercially processed flaxseed is often available as pre-ground (milled) flaxseed. This product undergoes rigorous processes to ensure a longer shelf life. Techniques like cold-milling help preserve essential fatty acids and nutrients by protecting them from heat damage.
These products are typically vacuum-sealed or nitrogen-flushed to reduce oxidation. Packaging design is crucial to maintaining the integrity of pre-ground flaxseed; opaque and airtight materials are standard. Despite these measures, consumers should check expiration dates and store ground flaxseed products in the refrigerator after opening.
By understanding the proper methods of handling and processing flax, consumers can enjoy the maximum health benefits and ensure their flaxseed remains fresh and nutritious.
