Garlic Essential Oil

1. Introduction to Garlic Essential Oil

Garlic Essential Oil is a highly concentrated natural essential oil obtained from the bulbs or cloves of garlic (Allium sativum L.). Garlic belongs to the Amaryllidaceae family and is believed to have originated in Central Asia. Today, it is widely cultivated in countries such as India, China, Egypt, Spain, and many other regions around the world.

Garlic has been valued for centuries in Ayurveda, Unani medicine, Traditional Chinese Medicine, and various folk healing systems. Its strong aroma and therapeutic properties come mainly from sulfur-containing bioactive compounds. When garlic cloves are crushed, a compound called Alliin is converted into Allicin by the enzyme Alliinase. Allicin is primarily responsible for garlic’s distinctive smell and many of its biological activities.

Garlic Essential Oil is generally extracted through the steam distillation process. The oil appears light yellow to golden in color, has a powerful characteristic odor, and is highly volatile. It is widely used in the food industry, pharmaceuticals, cosmetics, agriculture, animal feed, aromatherapy, and herbal formulations.

• If the color, smell, or texture changes significantly, the oil should not be used.
• Storage in a cool, dark environment helps preserve stability for a longer period.

10. Extraction Process

Step 1: Selection of Raw Material

Fresh, high-quality garlic bulbs are carefully selected.

Step 2: Cleaning and Preparation

The garlic cloves are cleaned and lightly crushed or chopped. This activates the Alliinase enzyme, leading to the formation of Allicin.

Step 3: Loading the Distillation Unit

The prepared garlic material is placed inside the distillation tank.

Step 4: Steam Passage

High-temperature steam passes through the garlic material, carrying volatile oil and sulfur compounds along with it.

Step 5: Condensation

The vapor mixture is passed through a condenser, where it cools and converts back into liquid form.

Step 6: Oil and Water Separation

The condensed liquid naturally separates into oil and water layers, and the essential oil is collected using a separator.

Step 7: Filtration

The extracted oil is filtered to remove any impurities.

Step 8: Packaging and Storage

The purified oil is packed in airtight dark-colored glass containers and stored under suitable conditions to maintain its quality and stability.
