Types Of Oil From Coffee Beans 

Coffee bean oil is derived from the coffee plant producing coffee beans. These beans can be processed in different ways to create two main types of coffee beans oil:

Green Coffee Bean Oil 

Green coffee bean oil is extracted from unroasted, raw coffee beans. The beans maintain their natural green color and are not subjected to any heat or roasting. 

To produce the oil, the green coffee beans are first cleaned and dried. Then the skin and pulp are removed from the beans. Finally, the inner green seeds or beans are pressed to extract the oil. 

Green coffee bean oil has a lighter color and milder aroma than roasted coffee oils. It retains much of its natural chlorogenic acids, caffeine, and antioxidant content since the beans do not undergo roasting. Some of the key benefits of this oil include:

  • High levels of chlorogenic acids have anti-inflammatory and antioxidant effects.
  • Increased caffeine content compared to roasted beans which can improve skin absorption.
  • Abundant antioxidants like polyphenols and tocopherols 
  • The smoother, less bitter flavor profile

Green coffee bean oil is prized in the health and beauty industries. When applied topically, it can nourish, hydrate, and rejuvenate skin. It also makes an excellent addition to anti-aging skincare products.

Roasted Coffee Bean Oil

Roasted coffee bean oil is derived from coffee beans that have been roasted to various degrees. This heating process causes the beans to undergo physical and chemical changes that alter their structure, color, and chemical composition. Darker roasts result in a stronger aroma and more bitter taste.

To extract roasted coffee oil, the beans are first roasted to the desired level, from light to dark. They are then pressed to derive the beneficial oils. Some traits of roasted coffee bean oil include:

  • Rich, warm aroma reminiscent of brewed coffee
  • The dark brown color that intensifies with darker roasts
  • Complex flavor notes ranging from smooth and sweet to bitter 
  • Lower acidity and caffeine compared to green coffee oil

Roasted coffee bean oil is valued for its crisper coffee-like fragrance. When diffused in aromatherapy, it can provide an invigorating scent that uplifts mood and reduces stress. It also adds a smooth coffee flavor when used for cooking or baking.

Extraction Methods Of Oil From Coffee Bean 

Extraction methods play a crucial role in obtaining coffee bean oil, which is widely used in various applications such as culinary, cosmetic, and pharmaceutical industries.

Here are some of the coffee bean oil extraction methods. 

Cold Press Extraction

Cold pressing is considered the optimal method for extracting oil from coffee beans because it preserves the integrity and chemical composition of the oil. This mechanical extraction technique involves crushing or grinding the coffee beans into a mash using a millstone or large press. The resulting pressure causes the oils to separate from the bean.

To qualify as true cold pressing, the temperature during the extraction process must be carefully controlled. The grinding and pressing action generates friction which can heat up the beans. Temperatures must remain below 49°C (120°F) throughout the process. This prevents damaging or degrading the delicate coffee oils.

The lower heat helps maintain the stability of the fatty acids, antioxidants, and aromatic compounds within the raw coffee beans. This results in the highest quality coffee bean oil with a full bouquet of nutritious fats, beneficial phytochemicals, and aromatic notes.

Benefits of this include:

  • Preserves more aromatic compounds and nutrients since no heat is applied
  • Simple equipment and process
  • No chemical solvent residues 

Challenges include:

  • Lower oil yields compared to other methods 
  • Labor-intensive batch process
  • Oil needs filtering to remove sediment

Overall, cold pressing is suitable for small-batch artisanal coffee bean oil production focused on quality.

Solvent Extraction 

In solvent extraction, coffee beans are mixed with a chemical solvent such as hexane which works to dissolve and separate out the oils from the bean matter. The solvent pulls the oils from the beans while leaving behind the fibrous material from the beans.

Common solvents used include hexane, ethanol, and petroleum ether. The beans and solvent are combined and then filtered or distilled to recover the solvent from the oil fraction. 

The solvent and oil solution are distilled to evaporate and recover the solvent for reuse. The remaining coffee oil is purified.

Benefits of solvent extraction include:

  • Very high oil yield and efficient process
  • Versatile for large-scale production
  • Lower cost than other methods

Challenges include: 

  • Risk of residual solvents remaining in the final oil 
  • Requires solvent recovery and disposal systems
  • Destroys more delicate aroma compounds

Solvent extraction is the cheapest and most productive option but requires significant safety and quality control measures.

Supercritical CO2 Extraction

Supercritical CO2 extraction exposes crushed coffee beans to carbon dioxide in a supercritical state. This means the CO2 is manipulated under extreme pressure and temperature to take on properties between a liquid and a gas.

The beans are placed in an extraction chamber then supercritical CO2 is pumped through at pressures above 74 bar and temperatures above 31°C. This allows the CO2 to thoroughly penetrate the beans and extract the oils. 

The CO2 with the dissolved oils is then put through a pressure reduction process, causing the oils to steadily separate. The oils are collected while the CO2 is recovered, compressed, and recycled back through the system.

Benefits of this method include:

  • Extracts only desired compounds leaving behind undesired ones
  • Avoids chemical residues or alteration of flavors
  • Enables oxygen-free extraction

Challenges include:

  • Very high capital costs for equipment
  • Complex and energy-intensive processes
  • Requires skilled technicians

Supercritical CO2 extraction preserves quality and avoids unwanted compounds. But the high costs limit it to niche producers.

Uses Of Coffee Bean Oil

Here are some of the coffee bean oil uses:

Skincare Products 

Oil from coffee beans is a popular ingredient in a variety of skincare products. It can be found in creams, lotions, serums, and masks. It is particularly beneficial in anti-aging products due to its antioxidant properties.

Body Scrub 

Coffee bean oil is often incorporated into body scrubs to provide moisturizing and smoothing effects while gently exfoliating the skin. The grounds are combined with coffee oil, as well as ingredients like sugar or sea salt. 

As the scrub is massaged into the skin, the coffee bean granules provide gentle abrasion to remove dull surface cells. Meanwhile, the coffee oil penetrates deeper to hydrate and nourish the skin. 

The caffeine in the oil can also provide some temporary tightening effects. This helps leave skin feeling exceptionally soft and smooth after rinsing off the scrub.

Biofuel 

Coffee bean oil contains fatty acids like linoleic, palmitic, oleic, and stearic acid that can be converted into biodiesel, providing a renewable fuel source. The process involves chemically reacting the triglycerides in the coffee oil with alcohol-like methanol through a process called transesterification. 

This causes the oil to split into esters and glycerol. The esters produced make up the biodiesel, while the glycerol is removed as a byproduct. The biodiesel can then be used to power diesel engines, providing a greener alternative to traditional petroleum diesel. 

Coffee bean biodiesel has similar efficiency and performance to regular diesel. The high oil content of coffee beans makes their oil well-suited for converting to fuel.

Cooking Oil 

With a high smoke point of around 225°C, it’s suitable to use coffee oil for cooking methods like frying, sautéing, roasting, baking, etc. It has a mildly nutty, aromatic flavor that infuses into food. The oil can be used independently or blended with other cooking oils.  

It also works nicely in salad dressings, marinades, sauces, and more. The antioxidant content of coffee oil provides added stability for cooking at higher temperatures.
