Camellia oil is a high-end oil in edible oil. The most important thing is that it has a high ignition point, so it is very suitable for cooking and frying food. Its shelf life is generally 18 months. Camellia oil stored for three years should not be used, because it will produce carcinogens such as aflatoxin if it is stored for too long.

Stewed soup and steamed camellia oil are the best, but less than ordinary oil. It is best not to eat for more than three years, but it can be made into injections and made into various ointments, pills or scalds (the longer the time, the better).

Expired edible oil can't be eaten, because there will be oil rancidity. Eating rancid edible oil will lead to the increase of saturated fatty acids, cholesterol and blood lipids, which has the risk of cancer and causes chronic diseases such as cardiovascular and cerebrovascular diseases, hypertension and diabetes.

Use:

1. When applying hand oil, if the skin on your hands is dry and cracked, you can try to put your hands in oil and soak your fingertips with oil often, and your nails will grow well, transparent and firm.

2. When using lubricating oil, for example, if the lock is difficult to open, you can put it in. Some bearings have been used for too long, so you can fall down and lubricate them. There are many of them. They are used reasonably and are environmentally friendly.

3, expired edible oil can grow flowers.

4. Soap that can be used to wash hands, according to a certain proportion, add alkali and a little rice.

5. Mechanical oil cannot be directly manufactured. Mechanical oil is specially treated, its chemical properties are relatively stable, and its structure and composition are different from those of edible oil. Using deteriorated edible oil in the machine can't play an ideal role.
