The Best Flaxseed Oil Processing Method
Flaxseed oil contains an adequate amount of linolenic acid and the oil is usually extracted by low-temperature physical squeezing in the flaxseed oil production line. Because flaxseed oil has a balanced proportion of linolenic acid and linoleic acid, which is 1:4, and it is scientifically proven that when the ratio of linolenic acid to linoleic acid is 1:4, the human body can be in the healthiest state, and it is very difficult for various external bacteria to invade. Flaxseed oil can meet human health standards.
However, linolenic acid is highly heat-sensitive and easily oxidized. When the critical temperature is exceeded, the activity of linolenic acid begins to be destroyed. Therefore, when making flax seed oil, it is necessary to choose the physical pressing method at low temperature without any heating treatment. Low-temperature physical squeezing retains the activity of linolenic acid, and no additives in the whole process to maintain the natural quality of raw materials. Second, the physical pressing temperature is lower than the melting point temperature of the wax, so that the pressed flaxseed oil is free from the “dewaxing” procedure and avoids the damage caused by the dewaxing process.
Processing Steps of Flaxseed Oil Physical Press Line
The pressing production process keeps the most effective ingredients in flaxseed, such as polyunsaturated fatty acids, protein, dietary fiber, vitamins, trace elements and so on. The pressed oil is more suitable for a special supplement for human health. Normal temperature pressing method refers to the flaxseed oil extraction at room temperature under great pressure from physical machinery without the traditional process of high-temperature frying or steaming, so the normal temperature pressed oil still distributes in the undeformed protein cells and contains rich ingredients (linolenic acid and other nutrients).
The steps of flaxseed oil press line are mainly: Flaxseed selecting → screening → cleaning up impurities → crushing → flaking → conditioning →normal temperature pressing → residue separation → degumming →dehydrating → debittering → crystallization → cryogenic filtration → physical pressed linseed oil
