Differences between Hot Press Flaxseed Oil And Cold Press Flaxseed Oil?

Flaxseed oil, which is also known as linseed oil in much of the world, has been known to humans for a surprisingly long time. Flaxseed oil can be divided into cold pressed flaxseed oil and hot pressed flaxseed oil.The raw materials of the two production methods are the same, are pressed with flaxseed, but the production process is different.

Flaxseed Oil Hot Pressing Method

The oil crop after high temperature fire or stir fry, and then after the physical compression of the oil, it is the more traditional pressing process, the oil rate is higher, suitable for cooking when eating.

Hot Pressing Process Characteristics

1.Improve the oil rate, improve the taste of oil, flavor is rich.

2.Easily lead to high temperature oxidation polymerization, decomposition of peroxide and some harmful substances, destruction of a kind of nutrients.

3.High temperature caused by protein denaturation, greatly reducing the flaxseed oil in the content of polyunsaturated fatty acids, and even produce trans fatty acids.

4.Impurities, such as flax seed dander, phospholipids, free fatty acids, etc., affect the appearance of oil color and the inherent quality of oil.

Advantages:Flaxseed oil taste rich mellow, the oil rate is high.

Disadvantages:High temperature fried seeds will reduce the content of active ingredients in oil, resulting in protein denaturation.

Flaxseed Oil Cold Pressing Method

At low temperatures, vegetable oils extracted with enormous pressure from physical machinery, which have not been subjected to conventional high temperature frying or steaming processes, so oils are still distributed in undeformed protein cells and contain very rich flaxseed ingredients (linolenic acid and other nutrients).

Cold Pressing Process Characteristics

1.To avoid high-temperature presses in the degradation of fat and sugar, and protein degradation caused by the harmful substances.

2.To avoid the high temperature caused by the flaxseed oil color becomes dark, there is the phenomenon of paste.

3.After multiple filtration, to avoid the hot pressing process of sulfuric acid degumming, caustic soda acid, activated clay decolorization process caused by chemical substances and a variety of active ingredients in direct contact with secondary pollution.

4.To avoid high temperature distillation deodorization, effectively prevent the high temperature on the flaxseed oil polyunsaturated fatty acids - α-linolenic acid damage, effectively retain the natural complete nutritional ingredients, more easy to human absorption and nutritional supplements.

Advantages:Retains almost all of the nutrients in flaxseed, refreshing taste is not greasy, polyunsaturated fatty acids rich in content.

Disadvantages:The oil rate is relatively low, the cost is relatively high.

The Taboo of Cold Pressed Flaxseed Oil

1.You can not use cold pressed linseed oil for high temperature heating cooking

Flaxseed oil is the most important raw nutrients - a linolenic acid is a very lively polyunsaturated fatty acids, which is a very rare natural antioxidants, once heated more than 45 ℃, this nutrient is destroyed. The higher the temperature, the longer the heating time, a-linolenic acid is more serious damage.

2.If you want to use rapeseed oil cooking, you can choose hot pressed flaxseed oil.

Flaxseed oil should not be stored for long periods after opening

Cold pressed linseed oil after opening, it is best to eat within 45-60 days, because a-linolenic acid is afraid of oxygen, after opening the bottle will be slowly stored long-term oxidation, loss of nutrition.

3.Do not put flaxseed oil under the sun

a-linolenic acid is sensitive to light, so the formal cold pressing linseed oil is mostly dark bottles, because it can play a role in the dark.

Edible method of cold pressed flaxseed oil

1.Flaxseed oil+condensed milk，Flaxseed oil added in the condensed milk inside, stir and eat evenly.

2.Flaxseed oil + yogurt, flaxseed oil added to the yogurt inside, stirring evenly, this is the best way to effect, yogurt is best homemade, you can buy pure milk and probiotics (lactic acid bacteria) to do their own, more fresh and more nutritious.

3.Flaxseed oil mixed with cold dishes, Now eat now mixed, because a-linolenic acid is afraid of oxidation, can not be exposed in the air for too long, otherwise the nutrients were destroyed.

4.Drink directly, drink before breakfast in the morning morning or before going to bed in the evening.If the stomach is not easy to diarrhea to change after dinner.

5.Add in the porridge, for the inconvenience of eating people, or children, you can put the linseed oil in the porridge, stir evenly eat, pay attention to the porridge can not be too hot, can only be warm.
