We will be able to tell if the spread is margarine if it has been hydrogenated.
A liquid unsaturated fat can be made into a solid fat by the process of hydrogenation. In order to make an unsaturated fat saturated, hydrogen atoms must be injected into it. Trans fat, a particular form of fat, is created during this hydrogenation process.
An unsaturated fat undergoes hydrogenation, changing from a liquid to a solid. Unsaturated fats become saturated ones as a result of this process. The remaining unsaturated fats undergo another molecular shape change during this phase. An "trans" form is the end outcome.
We must maintain both of them at room temperature in order to analyze the unidentified spread. The process of hydrogenating corn oil results in the production of margarine.
