It depends on the quality, variety or color of flaxseed. Reddish brown: 65,438+00% is imported from 3.7 yuan. It was made for about 4 yuan. If it is organic, it will be much more expensive, around 20 yuan. 1. Canadian imported gold flaxseed, about a kilo of 4 yuan and a kilo of brown 4 yuan; 2. Inner Mongolia, Liaoning and Hebei produce a new kind of flaxseed, 3.5 yuan per kilogram. Golden flaxseed, 4 yuan a catty; 3. Old flaxseed is produced in southern Gansu and Ningxia, 8 yuan a catty. Cheap twenty or thirty yuan, expensive one or two hundred yuan. I didn't quite understand the authenticity, so I made a special investigation. It means true orthodoxy. These may all be real linseed oil. The reason why the price difference is large is mainly related to the raw materials and production technology of the products. Like some transgenic linseed oil, the price of leached linseed oil is relatively cheap, while the price of hot-pressed linseed oil is in the middle. Cold-pressed linseed oil has low oil yield, complete nutrition retention and high price, which is three times that of hot-pressed linseed oil because of its good raw materials (which must be strictly screened). Around eighty, some well-known brands also have cold-pressed linseed oil. Cold-pressed linseed oil, Oriati used in my home is more expensive, with good quality and taste, without any bitterness and odor. When added to yogurt, the baby will not reject it, and the taste is light, which is easy for the elderly to accept. On the whole, it's good.
