Enfleurage 

Enfleurage is a technique in which odorless fats that are solid at room temperature are used to capture the fragrant compounds released by plants in order to preserve them. Enfleurage can be performed using either a "cold" or a "hot" method.

Step-by-step explanation

Floral oil is extracted using the enfleurage method, which involves placing petals between layers of purified animal fat that have become saturated with flower oil. Alcohol is then used to extract the absolute from the petals. From the traditional method of pressing with sponges to the more modern method of mechanical maceration, there are a variety of methods for extracting citrus oils from fruit peels. An individual chemical compound used in perfumery can be isolated from essential oils, which is usually accomplished through distillation, and it can sometimes be reprocessed to produce yet another perfumery chemical.
