Blended oil refers to the edible oil made by blending a variety of refined oils in proportion, which can generally be used for cooking, pancakes, fried food or cold salad. Because it is a mixture of various oils and fats, it can make up for other ingredients that can't be done by a single oil in nutrition.

However, the shelf life of blended oil is generally 12 months. If the purchase price is lower, it means lower cost, and low-grade oil may account for a large proportion, which is not good for human health. It is recommended to check the ingredients list when purchasing.
