Description

Manufacturing Method of Sesame Oil {METHOD FOR PREPARING OF SESAME OIL}

The present invention relates to a method of manufacturing sesame oil, and more specifically, sesame (or sesame powder) is selected and roasted by indirect heating method, and then milked and filtered so that the raw material is not burned, bitter taste is long, and the fragrance is long lasting and easy after opening. The present invention relates to a method of producing sesame oil that is not oxidized.

Sesame is a yearly vegetation of Sesameaceae, also known as Homa, Jima, and Scented Horses. It has many species of origin, and its origin is the southwestern savannah, an important plant of ancient civilization in ancient Egypt, India, etc. It has been cultivated. There are currently about 37 species, including wild ones, but only one species with the scientific name Sesamum indicum L.

The general composition of sesame seeds contains more than 50% lipids, 20% protein, 15% carbohydrates, and also contains fiber, minerals, vitamins, etc. Sesame oil is produced by roasting and squeezing sesame seeds. In Korea, it is a kind of seasoning that has been widely used in various dishes as a flavor rather than being accepted as a general fat or oil. Thus, the biggest reason that sesame oil has been used for a long time in our country is because of the scent of sesame oil. The scent of sesame oil is the protein and carbohydrates in the sesame during the roasting process of sesame, causing a mailald reaction to produce scents such as aldehydes, ketones, pyrazine, furan, and pyrrole. It is known to give a distinctive scent. The fragrance component of sesame oil is composed of about 100 or more kinds of ingredients, and the most influential flavor of sesame oil is known as a compound of pyrazine, and especially dimethyl pyrazine, specifically 2,6-dimethyl pyrazine And 2,6-pyrazine are known as the main compounds of sesame oil with a scent.

Currently sesame oil in circulation is mainly domestic and imported from sesame seeds or sesame powder. However, due to the continuing deficit of sesame oil manufacturers, the situation is focused on stopping the production of sesame oil or preparing measures to reduce production costs.

Recently, imported sesame oil is mainly made from cheap sesame seeds produced in Sudan, India, etc. to reduce production costs.

However, in the case of imported sesame oil, by mixing three or more kinds of raw materials, foreign substances or odors from sesame oil are produced because the product is added by adding flavors to supplement the taste and aroma, which is remarkably degraded, and by adding foreign substances when manufacturing sesame oil for cost reduction. There are many problems such as the occurrence and the promotion of rancidity, and accordingly, consumer's distrust of imported sesame oil and domestic sesame oil is increasing.

Therefore, while reducing the production cost, it is possible to maintain the taste and aroma of sesame oil and to prevent rancidity, continuous interest and research on the production method of sesame oil with excellent preservation are required.

Accordingly, an object of the present invention is to provide a manufacturing method of sesame oil having excellent preservation properties by preventing sesame oil (or sesame powder) because bitterness is eliminated and the taste and aroma of sesame oil are excellent.

In addition, an object of the present invention is to provide sesame oil excellent in taste and aroma and excellent in preservation.

In addition, an object of the present invention is to provide an indirect heating device used in the roasting process in the manufacturing method of the sesame oil.

Provide a heating device.

Hereinafter, the present invention will be described in detail.

In the present invention, the selected raw material (sesame or sesame powder) is heated by indirect heating without direct heating, roasted, and then milked and filtered to produce sesame oil, and the raw material does not burn and confirms that the sesame oil maintains its own taste and aroma. On the basis of this, the present invention has been completed.

In the present invention, raw materials (sesame or sesame powder) is selected and roasted by indirect heating method, and then milked and filtered so that the raw material does not burn, so the bitter taste of sesame oil is small, and the fragrance lasts long after opening, and the foreign substances are removed in sesame oil to remove odor and Provides a method of producing sesame oil with low rancidity and excellent preservation.

The manufacturing method of the sesame oil will be described in detail as follows.

First step: raw material selection

This process is to remove the foreign matter mixed in the raw material 1 to 3 times, and then completely remove the moisture to dry step.

The raw material may be whole sesame or sesame powder, it is preferable to use sesame powder in order to reduce the production cost.

In the sesame oil production method using the sesame powder, sesame powder is prepared by carrying out a conventional sesame powder production method of roasting and then grinding the naturally dried sesame seeds as described above.

Second Process: Indirect Heating

This process is to distribute the raw material selected in the first process by indirect heating method. This process is a step of heating by an indirect heating method by a heat transfer medium instead of the direct heating method of the conventional distribution method, it is preferable to heat for 20 to 30 minutes at a temperature of 40 ~ 90 ℃.

Preferably, the indirect heating is composed of three stages, and the indirect heating of the three stages is 10 to 15 minutes at a temperature of 35 to 45 ° C in one step, and 6 to 10 minutes at a temperature of 65 to 75 ° C in two steps. It is preferable to heat 3-8 minutes at the temperature of 85-95 degreeC by the step, More preferably, 12 minutes of 35-45 degreeC by 1 step, 8 minutes at the temperature of 65-75 degreeC by 2 steps, 3 steps Furnace is heated at a temperature of 85 to 95 ℃ for 5 minutes.

In this process, the raw material is indirectly heated by a heat transfer medium to prevent burning of the raw material so that it does not have a bitter taste, and can maintain the intrinsic taste and aroma of sesame oil to the maximum, and the fragrance lasts long after opening and is not easily oxidized.

Third process: milking

In this step, milking the raw material indirectly heated in the second process, the raw material discharged from the indirect heater is put in a tablet cloth and milked for 25 to 30 minutes.

4th process: filtration

This process is a step of filtering the oil milked in the third process. It is preferable to use a filter press for filtration of this process.

In addition, the sesame oil production method of the present invention may further comprise a natural precipitation step.

The natural precipitation step is preferably carried out in the middle of the third process and the fourth process as follows.

First step: raw material selection

Second Process: Indirect Heating

Third process: milking

4th process: natural precipitation

This process is a step of natural precipitation of the oil milked in the third process. The natural precipitation is preferably made for 6 to 10 days at a temperature of 32 to 38 ℃ in the natural precipitation purification tank.

If the precipitation temperature is less than 32 ℃ or more than 38 ℃ there is a problem that the precipitation does not sink and the precipitation does not occur, the precipitation is not made if the precipitation period is less than 6 days.

Sesame oil prepared through the natural sedimentation as described above can reduce the off-flavor and rancidity of sesame oil to remove sediment, or foreign matter clean.

5th Process: Filtration

This process is a step of filtering out the residue of the oil naturally precipitated in the fourth process. In this process, oil sedimented in the natural sedimentation tank is filtered by a filter press, so that the sesame oil-specific residues hardly remain. Sesame oil prepared as described above has the advantage of long shelf life due to less foreign matter, odor, and rancidity in sesame oil.

Sesame oil prepared through the process as described above does not have a bitter taste by preventing the burning of raw materials, it can maintain the unique taste and aroma of sesame oil as long as possible, and the fragrance lasts long after opening, and the foreign matter in the sesame oil by filtering through natural precipitation Eliminates off odor and rancidity and has excellent preservation.
