Which of the following is NOT one of the six enemies of oil?

Salt is not considered one of the six enemies of oil, which typically include water, air, heat, light, contaminants, and time. The main enemies of oil are substances and conditions that can degrade its quality and effectiveness over time.

Water introduces the potential for hydrolysis and can lead to emulsification in oils. Air, particularly oxygen, can cause oxidation, leading to rancidity and off-flavors in oils. Heat accelerates the rate of chemical reactions that can lead to spoilage and degradation.

Salt, while it can influence flavor and preservation in food contexts, does not have the same detrimental effects on oil as the other elements listed. Therefore, recognizing that salt is not on the list of factors that negatively impact oil helps highlight the unique characteristics of oil stability and preservation.
