What is the sesame oil (the technology and raw material selection of oil extraction)

Sesame oil is a common condiment with strong aroma and unique flavor, which is widely used in cooking in China. So, how is sesame oil squeezed out? Next, the technology and raw material selection of oil pressing are introduced.

Selection of raw materials

There are two main raw materials for oil pressing, one is sesame and the other is peanut. These two raw materials can produce rich oil in the process of oil pressing, so they are widely used in the production of sesame oil.

First, let's take a look at the production process of sesame oil. The production of sesame oil needs to choose fresh sesame as raw material. When selecting sesame seeds, we should pay attention to selecting sesame seeds with full color and no impurities to ensure the high quality of sesame oil.

However, to make peanut oil, fresh peanuts are needed as raw materials. Similarly, when choosing peanuts, we should pay attention to choosing peanuts with full color and no mildew to ensure the good taste of peanut oil.

Oil pressing technology

The process of oil pressing is mainly divided into five steps: cleaning, drying, crushing, pressing and filtering. Below, let's introduce each step in detail.

First, clean the selected sesame seeds or peanuts to remove impurities and dirt on the surface. You can use clean water or salt water when cleaning. After soaking the raw materials for a period of time, rinse them with flowing water.

After cleaning, dry sesame or peanuts. The purpose of drying is to remove water from raw materials, so as not to affect the subsequent crushing and pressing processes. The drying temperature should be controlled within a suitable range to avoid destroying the nutrients of raw materials.

After drying in the sun, crush sesame or peanuts. The purpose of crushing is to release the grease in the raw materials, which is convenient for subsequent pressing. Crushing can be carried out using equipment such as a crusher or a stone mill.

Crushed raw materials are squeezed. The purpose of pressing is to squeeze the oil out of raw materials and make sesame oil. Physical pressing or chemical solvent extraction can be used when pressing, and different methods will have a certain impact on the quality of sesame oil.

Finally, the squeezed oil is filtered. The purpose of filtration is to remove impurities and residues from oil and make sesame oil more pure. You can use equipment such as filter paper or filter screen for filtration.

final result

Through the above introduction, we know that sesame oil is squeezed out by washing, drying, crushing, squeezing, filtering and other steps. In the process of oil extraction, the selection and treatment of raw materials are very important. Only by selecting fresh raw materials and proper treatment can we make high-quality sesame oil. The production process of sesame oil also needs some skills and experience. Only by mastering the correct operation method can we make sesame oil with good export feeling and rich fragrance. I hope the introduction of this article can help you understand the production process of sesame oil.
