The cold-pressed edible oil of scarab and flaxseed usually has no peculiar smell, because it is extracted at low temperature and slow pressure, and has not been treated at high temperature, retaining the original nutrients and natural flavor, without adding any additives such as artificial flavors. However, if it is not properly preserved, such as exposure to sunlight or moisture, it may produce odor. Therefore, it is recommended to store it in a cool and dry place after purchase to avoid direct sunlight and humidity.
