4. Reduce fat and lose weight
Rape has a strong effect in promoting fat decomposition. People with high blood fat and obesity can reduce fat and lose weight by consuming rapeseed oil. In addition, rapeseed oil is the most easily digested oil, with a digestibility of up to 99% in the human body. Patients with hepatitis and cholecystitis cannot eat more other oils, so they can eat rapeseed oil.
5. Softening of blood vessels
Softening of blood vessels is rich in unsaturated fatty acids and vitamin E. These substances can soften blood vessels to a certain extent and delay human aging.
How to consume rapeseed oil correctly

How to store edible rapeseed oil
1. Low-temperature storage
Rapeseed oil needs to be stored in a low-temperature environment. If the temperature is too high, chemical reactions will easily occur, causing Changes in the composition of rapeseed oil will not only cause serious loss of nutrients but also cause rancidity. Therefore, when rapeseed oil is not in use, it should be kept away from stoves and sunlight and placed in a cool place.
2. Store away from light
Long-term exposure of rapeseed oil to sunlight will accelerate oxidation and rancidity. Under the action of ultraviolet light, it is easy to produce ozonides and produce bad odor and taste. . Affect rapeseed oil quality. Therefore, rapeseed oil should not be packed in white and transparent glass bottles. Plastic oil barrels have a certain degree of transparency, so barreled oil should also be protected from light. In addition, if an oil container is used for a long time, it should be cleaned regularly, drained of water before use, because the mixing of water will also accelerate hydrolysis and oxidative rancidity.
3. Sealed storage
Rapeseed oil is one of the edible oils that is prone to oxidation reactions. If rapeseed oil is exposed to large areas of air, it will easily oxidize. rancid. Therefore, every time after using rapeseed oil, the oil drum cap should be tightly closed in time to reduce the oxygen content as much as possible.
4. Add protective agent

After it becomes clear, pour the rapeseed oil into a glass bottle for storage. This can extend the shelf life of the rapeseed oil.
