How you store cooking oil affects its nutritional value! Are you doing it right?
Cooking oil plays an indispensable role in our cooking life. It not only affects the taste and aroma of food, but also directly affects our health. However, have you ever thought that the cooking oil you use actually has its own unique storage method? Improper storage may significantly reduce the nutritional value of these oils.
All oils will gradually degrade under the influence of heat, light and oxygen; proper storage can slow this process.
Experts point out that the ideal storage environment for cooking oil is a cool, dry, dark place. When oil is exposed to air and light for a long time, it will cause oxidation reaction and produce substances that are harmful to health. Therefore, when choosing a storage container, it is best to use a light-proof bottle and try to minimize the time the bottle mouth is in contact with the outside world.
Shelf life of different types of oil
The shelf life of different cooking oils varies. Oils high in monounsaturated fats, such as walnut oil, can be kept for about a year, while oils high in polyunsaturated fats, such as soybean oil, are recommended to be used within six months. Some oils, such as walnut oil, may not be safe to use even after the best before date on the package.
Oils high in saturated fat, such as avocado oil, have a longer shelf life and can be safely stored at room temperature, while oils low in polyunsaturated fat may not be stable.
It is worth noting that although saturated fat can extend the shelf life, consumers should also pay attention to the intake of such oils, because excessive intake of saturated fat is associated with the risk of cardiovascular disease.
Oil cooking and its health effects
During the cooking process, heating of oil changes its properties. Oil that is not stored properly will produce carcinogens when cooked at high temperatures. Therefore, choosing the right oil and storing it according to your cooking needs is essential to protecting your health. Especially when frying, the oil should be changed regularly and the cooking temperature should be controlled to avoid the production of harmful substances.
Studies have shown that repeatedly heating oil accelerates its deterioration and releases substances that are harmful to health.
Healthy Storage Habits
In addition to choosing the right storage container and location, refrigerating the oil is also an effective measure to maintain its freshness. Refrigeration will extend storage time, but the oil should be allowed to warm before use to prevent it from thickening. When disposing of used cooking oil, place it in a sealed non-recyclable container and throw it into the trash. This will avoid environmental pollution and ensure safety.
Proper disposal of used oil is an important step in environmental protection. Do not pour it into the sewer at will, causing water pollution.
Conclusion
As our awareness of health improves, we need to be more cautious in the use and storage of cooking oil. Are you confident in the cooking oil you store?
