Hydrolytic rancidity happens when water breaks down the triglycerides, often due to moisture or enzymes. The Difference Between Spoilage and Rancidity Spoilage in the microbial sense—like mold or bacterial growth—is rare in vegetable oil due to its low water content.
Understanding Why Vegetable Oil Turns Bitter and Rancid
If you detect a smell reminiscent of crayons, old nuts, mustiness, or a general "off" odor, oxidation has likely begun. There are two main types: hydrolytic and oxidative.
Additionally, avoid using wet utensils or introducing moisture into the bottle, as water droplets can accelerate hydrolytic rancidity. Oxygen is the fuel for oxidation, so reducing the headspace in the bottle directly slows down the rancidification process.

Refrigeration is an even better option for prolonging freshness, particularly for oils high in polyunsaturated fats like safflower or sunflower oil. Oxygen is the fuel for oxidation, so reducing the headspace in the bottle directly slows down the rancidification process.
