First of all, corn germ oil is refined by dephosphorization, deacidification, degumming, decolorization, deodorization and dewaxing on the basis of corn refined oil, which is a clarified, transparent and fragrant oil, with a high soot point, which produces rich bubbles when cooking, so as to make the ingredients better moisturized, and is not easy to be oxidized, so that it can keep the freshness of the ingredients and the original flavor. When frying food, these characteristics of corn germ oil make it more suitable for cooking.
Secondly, corn germ oil is suitable for high-temperature cooking because of its high stability, which allows it to remain stable at high temperatures without producing harmful substances due to overheating. In addition, corn germ oil also helps to lower cholesterol and reduce the risk of cardiovascular disease.
While rice oil is also a high-quality cooking oil, it has a lower smoke point and is prone to produce soot and harmful substances at high temperatures, and its stability is not as good as that of corn germ oil, so it may not be as suitable for high-temperature frying in the cooking process.
Overall, corn germ oil is more suitable for deep-frying in terms of both the list of ingredients and the preparation steps.
