Preserving Fragrance And Taste: Distillation's Delicate Art

Distillation is an extraction process used in perfumery and the food and beverage industry to capture essential oils from flowers or plants using water vapour. The process can also be used to capture the essence of a place, as demonstrated by artists Yeb Wiersma and Lotte Geeven, who captured the scent of a city in Belgium through distillation. In this process, the fragrance is separated from the raw materials. To preserve the fragrance, the distillate can be mixed with carrier oil and alcohol in a 3:1 ratio. Distillation columns are generally used for different lots/products and the liquid distributors must be robust enough to cover large liquid load ranges.

Mix oils and alcohol in a 3:1 ratio

To preserve fragrance and taste during distillation, it is important to mix oils and alcohol in a 3:1 ratio. This means that for every three parts of oil, you add one part of alcohol. This mixture helps to dilute the concentrated fragrance oils, which can be sensitive to high temperatures, and preserve the perfume or fragrance.

When mixing oils and alcohol, it is important to use a carrier oil as the base. Carrier oils are typically derived from plants or nuts and have a neutral scent, allowing the fragrance oils to shine through. Some popular carrier oils include sweet almond oil, jojoba oil, and fractionated coconut oil.

The type of alcohol used is also important. For perfume or fragrance distillation, perfumers often use a high-proof, odourless alcohol, such as perfumer's alcohol or ethanol. This helps to ensure that the scent of the fragrance oils is not overwhelmed or altered by the alcohol.

Once the oils and alcohol are mixed, it is crucial to store the mixture properly to preserve the fragrance. Transfer the mixture to clean glass bottles or vials, cap them tightly, and store them in a cool, dark place. Allow the scent to mature and blend for at least a week before using or selling the perfume.

By following these steps and mixing oils and alcohol in a 3:1 ratio, you can effectively preserve the fragrance and taste during distillation, creating a high-quality perfume or fragrance product.

Store in a cool, dark place

To preserve fragrance and taste during distillation, it is important to store your distillate in a cool, dark place. This is because exposure to sustained high temperatures can lead to decomposition and cracking of the components, which can alter their smell and colour.

For example, if you are making perfume, you should mix the oils and alcohol in a 3:1 ratio (oil to alcohol) to dilute the concentrated fragrance oils and preserve the perfume. Then, pour the mixture into clean glass bottles or vials, cap tightly, and store in a cool, dark place for at least a week to allow the scent to mature and blend.

Distillation is one of the extraction processes used in perfumery to capture essential oils from flowers or plants using water vapour. There are a total of 1000 natural and 3000 synthetic raw materials available, and new materials are discovered and marketed every year.

Fragrance extraction refers to the separation process of aromatic compounds from raw materials, using methods such as distillation, solvent extraction, expression, sieving, or enfleurage.

Use a perfume distiller

Distillation is an extraction process used in perfumery to capture essential oils from flowers or plants using water vapour.

To preserve fragrance and taste during distillation, the temperature must be kept low. This is because exposure to sustained high temperatures can lead to decomposition and cracking of components, which can alter their smell and colour.

To use a perfume distiller, you will need to mix the oils and alcohol. Mix the distillate with carrier oil and alcohol in a 3:1 ratio (oil to alcohol) to dilute the concentrated fragrance oils and preserve the perfume. Once mixed, pour the perfume into clean glass bottles or vials, cap tightly, and store in a cool, dark place for at least a week to allow the scent to mature and blend.

After a week, you can label the bottle or vial with the fragrance name and the date it was created. It is important to store the perfume in a cool, dark place to preserve the fragrance and taste.

You can also preserve the fragrance and taste of your perfume by using a vacuum distillation column. This will help to keep temperatures low during processing, preventing the decomposition and cracking of components that can alter their smell and colour.

Use gauze packing

Gauze packing is a preferred method in the flavour and fragrances industry. It is used to keep temperatures low during the distillation process, which is important as exposure to sustained high temperatures can lead to decomposition and cracking of components, altering their smell and colour.

Gauze packing is made of various metal wires, such as stainless steel wire, monel wire, copper wire, and then woven into wire gauze. It has low-pressure drop and high separation efficiency. It is suitable for precise distillation and vacuum distillation devices.

Sulzer Chemtech's metal wire gauze packing, BXPlus, is designed for applications in vacuum distillation where minimal pressure drop per theoretical stage is crucial. The direction of the vapour flow smoothly changes at the interface between two elements, leading to a reduction of the vapour flow velocity and shear forces, resulting in a decreased liquid hold-up at the element transition.

BXPlus is the preferred packing for applications where a short residence time is critical to prevent the degradation of heat-sensitive products. Due to its self-wetting wire gauze material, BXPlus provides excellent liquid distribution even at very low liquid loads.

Use distillation columns under vacuum conditions

Distillation columns are generally used for different lots/products and the liquid distributors must be robust enough to cover large liquid load ranges. Gauze packing is preferred in the flavour and fragrance industry.

To preserve fragrance and taste during distillation, distillation columns are often operated under vacuum conditions to keep temperatures low during processing. This is because exposure to sustained high temperatures can lead to decomposition and cracking of components, which can alter their smell and colour.

Vacuum conditions ranging from 0.7 – 400 mmHg are used to keep temperatures low during the processing of large organic molecules, which are thermally sensitive.
