What does hydrogenated mean in the context of oils?

It refers to oils that are naturally sourced
It involves the removal of oxygen from oils
It is a process to make oils more solid by adding hydrogen
It pertains to the extraction of oils from plants

The correct answer is: It is a process to make oils more solid by adding hydrogen

Hydrogenated, in the context of oils, refers to a specific process where hydrogen is added to liquid oils to transform them into a more solid form. This process is primarily used to increase the shelf life and stability of oils, making them more suitable for various cooking and food production applications. By converting unsaturated fats into saturated fats through hydrogenation, the consistency of the oil is changed, often resulting in a spreadable product like margarine or shortening. This transformation not only impacts the physical state of the oil but can also modify its nutritional profile, as hydrogenated oils may contain trans fats, which have been linked to various health concerns. Understanding this process is crucial for dietary management professionals, as it directly influences food choices and nutritional recommendations.
