Flaxseed oil solidifies in the fridge. Is this natural or does it lose its quality?
In decreasing temperatures, Flaxseed oil becomes more and more viscous until it starts to solidify. This is a natural property of the oil and does not mean a quality defect. Incidentally, Flaxseed oil can also be stored in the freezer to extend its storage life. This makes sense particularly if you are planning a longer trip. This does not damage the oil and it will quickly regain its usual properties when returned to room temperature.
