What is fake soybean oil blended with

Pseudo soybean oil is usually made by blending inferior vegetable oil, essence, pigment and other ingredients. Common adulterants include gutter oil, palm oil, cottonseed oil, essence additives, industrial pigments, etc. Long term consumption may be harmful to health. It is recommended to purchase through legitimate channels and check the product quality inspection report. The gutter oil mixed in fake soybean oil usually comes from the recycling of catering waste oil, which contains a large amount of harmful substances and oxidation products, and may produce carcinogens during high-temperature cooking. Palm oil is often used as a substitute due to its low price, but its high content of saturated fatty acids may increase the risk of cardiovascular disease if consumed in excess. Cottonseed oil contains the natural toxin gossypol, which can easily cause toxic reactions if not refined. Essence additives are used to imitate the special flavor of soybean oil, but some synthetic ingredients may cause allergy. Industrial pigments are used to adjust the color of oil products, and illegally used synthetic pigments may have liver and kidney toxicity. Some illegal merchants also mix mineral oil or animal fat to reduce costs. Mineral oil belongs to non food grade petroleum derivatives, and ingestion may cause gastrointestinal dysfunction. There is a significant difference in the fatty acid composition between animal oils and vegetable oils, which may affect the metabolic balance of the human body. These blending methods are often achieved by diluting pure soybean oil, requiring professional instruments to identify the product during testing. Consumers can make preliminary judgments by observing the transparency of the oil, whether the smell is pungent, and whether it solidifies quickly at low temperatures.

When purchasing edible oil, one should pay attention to the food safety labels on the packaging and prioritize non GMO soybean oil produced by pressing technology. Daily storage should be sealed away from light, and it is recommended to use it within three months after opening. If the oil is found to have a harshness, abnormal color or too much foam during heating, stop using it immediately. Regularly changing the type of edible oil can help balance the intake of fatty acids, and pairing with nut foods rich in vitamin E can reduce the damage of oil oxidation to the body.
