Greennor cold-pressed organic linseed oil originated from the original ecological flax manor in Wulanchabu, Inner Mongolia, and is the partner of Beijing Satellite TV Yangshengtang. Rich in α -linolenic acid, it is an effective method to supplement linolenic acid. However, in the process of eating, we must pay attention to several points: (1) Avoid cooking with linseed oil at high temperature, because the most important primary nutrient of linseed oil, a- linolenic acid, is a very active polyunsaturated fatty acid. It is a very rare natural antioxidant. Once heated above 45 degrees, this nutrient begins to be destroyed. The higher the temperature, the longer the heating time and the more serious the damage of α -linolenic acid. (2) Flaxseed oil should be eaten as soon as possible after opening the bottle to avoid long-term storage, because a- linolenic acid is afraid of oxygen and will slowly oxidize after opening the bottle for a long time, so it is necessary to use up the oil as soon as possible, and pay attention to cover the bottle cap after each use; (3) Keep away from light. Linseed oil should not be placed where the sun can shine. A- linolenic acid is afraid of light. Because of this, the cold-pressed organic flaxseed oil of Greno is packed in a dark bottle, which can protect it from light. (4) Open flaxseed oil should be kept in the refrigerator at low temperature.
