I'm an expert in the field of chemistry and food science, and I'm here to provide you with a comprehensive understanding of refined oil.
Refined oil is a term used to describe the process of treating crude oil to remove impurities and improve its quality for various applications. This can include edible oils used in cooking and non-edible oils used in industrial processes. The refining process is crucial because crude oil, straight from the source, contains a variety of impurities that can be harmful to health and undesirable for specific uses.
The refining process typically involves several steps:
1. Degumming: This is the initial step where gums and other impurities are removed from the crude oil. Gum is a type of phospholipid that can affect the oil's stability and quality.
2. Neutralization: In this step, the oil is treated with alkali to neutralize free fatty acids, which can contribute to rancidity and a bitter taste.
3. Bleaching: The oil is then bleached to remove color bodies and other impurities that can affect the oil's appearance and flavor.
4. Deodorization: This is the final step where volatile compounds that contribute to the oil's odor and flavor are removed under high vacuum and heat.
5. Winterization: Sometimes, an additional step is included to remove waxy components that can solidify at lower temperatures, thus ensuring the oil remains liquid under cold conditions.
The term refined implies that the oil has undergone this series of processes to achieve a higher level of purity and quality. However, it's important to note that the term does not necessarily imply that the oil is free from all chemicals or additives. Some refining processes may involve the use of chemicals that are later removed, but the presence of these chemicals is regulated to ensure safety.
The refining process is designed to enhance the oil's shelf life, flavor, color, and overall quality. It's a balance between removing unwanted components and preserving the beneficial properties of the oil.
In terms of edible oils, refined oils are often preferred for their longer shelf life and neutral flavor, which allows them to be used in a variety of cooking methods without imparting their own distinct taste. However, some consumers and health advocates prefer unrefined or cold-pressed oils for their natural state and the retention of more nutrients.
It's also worth mentioning that the refining process can vary depending on the type of oil and the desired end product. For instance, some oils may undergo additional steps or different methods to cater to specific culinary or industrial needs.
In conclusion, refined oil is a term that encompasses a variety of processes aimed at improving the quality and safety of oil for consumption or use. It is a critical step in ensuring that the oil is fit for its intended purpose, whether that be cooking, manufacturing, or other applications.

Definition: An oil has been refined by using chemicals that are harmful to us. In short it means to 'purify'. But the meaning of purify has many definitions. It may mean the oil was treated with acid, or purified with an alkali, or bleached. It can also be neutralized, filtered or deodorized.
