What kind of sesame oil do you want to make?

The oil content of sesame is as high as 50% (45%~63%).  Before make your own sesame oil or starting your sesame oil plant, the first step is to determine the type of sesame oil you want to produce. Sesame oil is generally divided into:

  • Light Sesame Oil: Refined sesame oil which has light color and light flavor. Commonly used for cooking in the Middle East, South India, halal markets and East Asian countries.
  • Dark Sesame Oil: Made from roasted/toasted sesame seeds and has dark color, stronger flavor and aroma. It’s primarily used for seasoning, not cooking.

Common Sesame Oil Extraction Methods

There are 3 main oil extraction methods for sesame oil production:

  • Water Extraction Process (Aqueous extraction) by use of stone mill.
  • Mechanical Pressing Process by use of screw oil press & hydraulic oil press.
  • Solvent Extraction Process

The sesame oil extracted by water extraction method has special aroma, commonly known as the traditional production process of roasted sesame oil. With the development of oil pressing technology, mechanical pressing process is becoming a better choice for sesame oil production. View the introduction below to learn more about the details of these 3 common oil extraction processes.

  1. Wash and soak the sesame seeds for 1-2 hours. The moisture content of the seeds is about 25%~35% after soaking.
  2. Cook the seeds with big fire until the sesame seeds are bulged, and then switch to soft fire. After the seeds are cooked, pour some cold water (about 3% of the amount of cooked seeds) into the cooker. Then stop cooking after about one more minute. The temperature is about 190℃~200℃.
  3. Cool the toasted sesame seeds down to about 65℃~75℃, free the smoke and remove the burnt pieces and broken skin.
  4. Grinding the toasted sesame seeds to sesame butter. The finer the sesame butter is ground, the better for the separation of oil. The speed of the stone mill and the grinding temperature can affect the flavor of sesame oil.
  5. Water Adding and Mixing: This is the key process of toasted sesame oil production. Add boiling water equal to 80% to 100% weight of sesame seed paste in 4 times.
  6. Vibration and Oil Separation: Separate the oil from the sesame butter mixture.

Mechanical Oil Pressing & Solvent Extraction Process

It is now the BEST Choice for both Toasted Sesame Oil Production and Untoasted Sesame Oil Production!

Tips for Sesame Oil Manufacturing Business

The characteristic of toasted sesame oil extraction is to maintain the flavor of sesame oil. Reasonable control of processing temperature is the key.

  • Proper increase of pressing temperature is beneficial to the conversion of sesame ether into sesame phenol with special flavor. But pay attention to control the temperature. If too high, the oil color will turn black and the oil cake will be burnt.
  • Mechanical pressing method can refer to the cooking process of stone milling method (water extraction) to produce toasted sesame oil.
  • The oil cake can be further extracted by solvent. The solvent extracted oil will be refined and be processed into cooking oil. The inherent flavor of sesame seeds flavor is lost after refining.
  • In order to make full use of sesame oil cake to develop high quality sesame protein powder, it is suggested to peeling the sesame seeds before oil expelling.


Comparison of Common Sesame Oil Production Process

   Water Extraction Process 
(Stone Mill)
Advantages Disadvantages
  • The oil has unique and strong fragrance:
  • The yield of oil is relatively low.
  • The sesame paste residue after oil extraction has high moisture content, serious protein degeneration and poor quality, difficult to separate and use.
  • It is mostly intermittent production which has high labor intensity and long processing cycle.
Main Application: It should be your first choice if you are very concerned about the preservation of the fragrance of toasted sesame seeds.


   Mechanical Pressing Process
(Screw Oil Expeller / Hydraulic Press)
Advantages Disadvantages
  • High oil yield
  • Get not only high quality of sesame oil, but also high quality of sesame oil cake.
  • Simple process, low labor intensity, easy industrialization.
  • Low investment, high production efficient.
  • The oil fragrance is lighter than that of water extraction process.
Main Application: It is not only suitable for running mini oil mill, but also suitable for medium to large scale industrial sesame oil production business.


   Solvent Extraction Process
(by extracting solvent)
Advantages Disadvantages
  • High oil yield.
  • Low labor intensity, easy industrialization.
  • Lack of fragrance.
  • The crude oil has high content of wax, dark and cloudy color. The crude oil need to be refined to produce edible oil.
  • More equipment, large investment, and high production cost.

Main Application: Extract oil from sesame oil cake.

Global Market of Sesame Oil Extraction

Sesame oil is one of the world's healthiest oils due to its abundant content of vitamins and minerals. It is known for its endless list of health benefits namely to improve hair and skin health, support healthy bones and teeth, regulate blood pressure, decrease the risk of cardiovascular diseases and increase the overall health of the heart, avoid development of cancer cells, manage better digestion, promote resistance among infants, and combat stress and anxiety through massages. As of 2012, the sesame seed had a market price of 0.67 USD per pound, making it a relatively expensive commodity due to its short supply and high demand in the world market.

Production Quantities of Sesame Seed by Country

It is originated in the Middle East and is abundant in India, China, Sudan, Myanmar and Uganda now. The planting area of sesame in these five countries accounts for more than 75% of the world's planting area, 7 million hectares per month, and the total output is about 3 million tons.

The market for sesame oil is mainly located in Asia and the Middle East where the use of sesame oil has been a tradition for centuries. Now a days, sesame oil is popular in many countries, especially in China, Korea, Japan, South India and Thailand. Besides, about 65% of the annual US sesame crop is processed into oil and 35% is used in food.
  • Untoasted sesame oil is produced using the cold-pressed extraction process, contains the most natural form of the oil. With its faint and mild flavor, the oil's naturally high level of antioxidants are also best preserved, and the process’s prosaic effect promotes better shelf life. Cold-pressing type sesame oil extraction machines administer the precise amount of force to crush the seeds and apply a good amount of friction to heat the seeds naturally. The machine's expeller mechanism then keeps the oil at temperatures not higher than 120 degrees Fahrenheit which is why oils produced this way are called cold-pressed.

  • Toasted sesame oil is best known for consumers who want the oil with better flavor and a more fragrant aroma. Due to the cooking process, the oil has a darker color and strong fragrance. The sesame seeds are cooked to degenerate protein and create high quality hot-pressed sesame oil with the best flavor.

Sesame oils are highly beneficial for the human body. They contain natural contents of nutrients that can improve health processes and they taste and smell great. However, due to the delicacy of sesame seeds towards the extraction process, manufactures employ the help of sesame oil extraction machines to prevent wastage of quality sesame oil and improve its supply so that a bigger market can enjoy the benefits of sesame oil.
  • Hi, I think refrozen and filtered oil is the best way to have a good quality. If you can tell us approximately how much it costs to get each method (refined versus refrozen & filtered) it will be awesome. As i told you, we are opened to your propositions as you are the supplier. After that I want you to bring us process diagrams of each method ( just the equipments, their functions and the total space required) will be perfect to me and my partners to take a decision. We want to begin with a small production as i told you (250 kg/ hour) with a good rate of oil yielding, and after we will see.
    I also want to know if i use 1 kg of sesame , what quantity of sesame oil in liter i will obtain (in each method if possible).
  • Hi,
    1. As for pressing section, it's same flowchart, which includes, cleaning, cooking, pressing and filtering process.
    2. As for purification section, there's two way:
        2.1. Refining - the mini capacity of refinery system is 1TPD. This system includes deacification, degumming, decoloring and deodorization process. After the refinery, the oil color is very light, and almost no fragrance smell.
        2.2. refrozen and filtering - the min capacity is also 1TPD. This system includes cooking tower, freezing vessel and filtering process. After this purificatioin, the oil color is still deep, and with fragrance smell.
    The cost for each part has been sent to your email, please check it.
    By the way, the two purification method will not effect the oil yield rate too much,
    the oil yield rate is decided only by pressing.
    FYI, you could get around 0.4kg oil from 1kg sesame seed, but this data will also be effected by the operation.
