Cooking oils have the ability to not only adequately cook food but also improve its flavour. Almost all recipes use oils, making them a crucial component of cooking. However, they can soon become rancid if they are not stored properly, even before their expiration date. Here are some methods to make them last longer as well as how to tell if the oil is deteriorating.
Do cooking oils go bad?
Let's first examine if cooking oils can genuinely degrade. In fact, they can. Cooking oils do go rancid if they are stored improperly or after their expiration date. Weather conditions and the calibre of the container they are stored in are also important factors. You must choose premium quality oils because they will last a long time and are secure to use because low quality oils can spoil quickly even when stored properly.
How to know if the oil has gone bad?
There are a number of signs that your oil is deteriorating or about to do so. The smell is the first one. Your oil may be rotting if you notice even a little trace of a sour or rotten smell that is substantially different from its normal aroma. In addition, there's appearance. It is clear that the oil has deteriorated if you see that its colour is changing or that mould is growing inside of it. Oils start to thicken once they start to get rancid, so you might also notice a change in thickness.
Storing in kitchen
The majority of culinary oils are kept in the kitchen, where they are conveniently located. Certain oils, including ghee, mustard, olive, peanut, coconut, and vegetable, must always be kept at room temperature. Always keep these oils in dry, cool storage in high-quality containers. Sunlight and warm weather can break down the oils and hasten their deterioration.

Simply remove a small amount of oil from a larger bottle if you have one. Use the oil in the smaller container for regular cooking and simply top it off when it runs out. You won't have to repeatedly open and shut the larger bottle, thus preserving the oil's freshness.
Storing in refrigerator
Sunflower and sesame oils must be kept in the refrigerator since they are more fragile than other types of oils. These oils may grow foggy when kept in the refrigerator, but it doesn't indicate that they are bad. The oils will stay fresh for a long time if the temperature is cold. Simply remove the oil 30 minutes prior to use to allow it to regain its regular texture.
Tips to retain flavours
Always keep cooking oils in a spotless jar or container. The best alternative for them is to use glass or metal containers. Use containers that can withstand the cold if you're storing in the refrigerator. Regardless of the type of oil, it is imperative to keep them away from light. Always keep them covered, out of the way shelves away from direct light. Before purchasing cooking oils, always verify the "best before" date. Prepare sure to make small amounts of ghee at home and use it within a month.
