Edible oil is an indispensable part of our daily diet. There are many kinds of edible oil in the market, and the degree of refining is also different(Edible oil refinery plays an important role in the food industry). So, does the higher the refining degree of edible oil mean the better? This problem needs to be analyzed from the perspective of science and health.

First, the refining of edible oil is to remove impurities in raw materials, including water, colloid, acidic substances and possible harmful components, such as pesticide residues or heavy metals. Refining can improve the purity of oil products and make them more stable in the cooking process, and it is not easy to produce smoke or odor. Therefore, from the perspective of food safety and convenient use, moderate refining is necessary.

However, excessive refining may lead to the loss of some nutrients in edible oil. For example, unrefined virgin olive oil is rich in vitamin E, polyphenols and other antioxidant components, which are beneficial to human health. Highly refined oil products usually remove these natural nutrients, leaving only pure fat. This means that excessive pursuit of refining may sacrifice the nutritional value of edible oil.(Harm of excessive refining of edible oil)

Besides, different types of edible oils have different requirements for refining degree. Some vegetable oils, such as rapeseed oil and soybean oil, need to be refined to a higher degree because the raw materials may contain more impurities. Traditional pressing oils such as sesame oil and peanut oil can retain their unique flavor and nutritional value after simple treatment, so it is not suitable for over-refining.

For consumers, the choice of edible oil should be based on their own needs and cooking habits. If you pay attention to health, you can choose virgin olive oil or cold-pressed linseed oil, which is less refined but rich in nutrition. If you pay more attention to the stability and taste during cooking, you can choose a moderately refined vegetable oil, such as rapeseed oil or sunflower oil.

In a word, the higher the refining degree of edible oil, the better, but the need to find a balance between safety, nutritional value and use demand. When purchasing, consumers should read the labels carefully, understand the processing methods and applicable scenarios of oil products, and choose the products that best meet their own needs. Healthy eating not only pays attention to the ingredients themselves, but also includes scientific choice of details.
