Ever wonder why restaurants have a unique smell? Or why your grandma’s kitchen smells so good? Like every other element of the food preparation process, scent is a hugely important part of cooking.
Aromatic ingredients like garlic, onion, and herbs can make or break a dish. So it’s important to use quality spices.
Cooking oils also make a huge impact in your food preparation.
In this post, we’ll talk about what oils don’t go rancid?
Let’s find out!
What Oils Don’t Go Rancid?
A lot of people think that olive oil is the only oil you can use to cook your meats and vegetables. While this is true for a lot of people, the truth is that olive oil does go rancid although not so quickly like corn or vegetable oil but it does.
This is because olive oil is a monounsaturated fat. There isn’t a lot of research on pure monounsaturated fats, but what we do know is that they have a tendency to go rancid.
The best way to tell if your oil has gone rancid is to smell it. If it smells sour or bad, it’s rancid. While olive oil does go rancid, there is one oil that doesn’t, and that is walnut oil.
Walnut oil is pressed from the nuts of the walnut tree. It is a polyunsaturated oil. Polyunsaturated fats usually don’t go rancid very fast. This is because the double or triple bonds that prevents the oil to go rancid.
There are many myths about rancid oil, but the truth is that it is perfectly healthy for you to consume. It only becomes unhealthy when it’s heated to the point of becoming oxidized which alters its chemical structure.
When food reaches room temperature, good bacteria begins to grow on it and cause give you positive health benefits.
However, in hot temperature, it can make it an ideal environment for oxidation (rancidity) to occur. Since antioxidants like vitamin E can prevent this oxidation process from occurring, foods high in antioxidant properties are more resistant to rancidity. But once the rancidity overtakes it can deplete the body’s vitamin E and B reserves.
2. How Long Rancid Oil Can Be Stored?
Rancid oil is healthy only if it’s used in moderation.
However, it can lead to health problems like botulism and diabetes. It can also cause digestive problems because of the presence of free fatty acids which are formed during the process of oxidation.
Rancid oil can be stored for extended periods (3-6 months) if it is stored correctly and in the right conditions.
Store your oils in a cool, dark place that’s away from direct sunlight or heat sources. Avoid storing oils near ovens or stoves as these appliances give off heat which accelerates oxidation process. The ideal storage temperature varies according to the type of oil you’re using.
3. Is Non-Rancid Oil Expensive?
Non-rancid oil actually means walnut oil. So is it expensive?
The price for walnut oil depends on the type you are purchasing. There are two grades of walnut oil. Pure walnut oil is more expensive than refined walnut oil, which costs about one-third less.
Walnut oil is very good for the skin. It can help eliminate wrinkles and keep your face looking young. Walnuts also help to give your hair shiny locks and make it easier to manage. You can use walnuts in salads or eat them plain, but their flavor will not be masked by anything else if you do this; they are strong enough to stand on their own!
