Description

Using technology to reduce benzopyrene peelings of sesame oil production methods.

The present invention relates to a method for producing sesame oil, and relates to a method for reducing benzopyrene content in sesame oil by inhibiting the production of benzopyrene, a carcinogen generated during sesame oil production.

Sesame is an important oily ingredient from ancient times, and it is a favorite food that has been widely known not only in Korea but also in Asia because of its flavor. In addition, sesame oil has a lot of lignans, the antioxidant activity is very strong and the oxidation safety is superior to other edible oils and fats.

Traditionally sesame oil is produced by heating and pressing, and its taste, aroma and color are important. In particular, according to the old manufacturing method when roasting at a high temperature, the taste and aroma are stronger, and the production yield is higher, so many companies stick to the high temperature.

However, in the traditional method of sesame oil production, benzopyrene is inevitably produced in large quantities.

 Benzopyrene is a type of polycyclic aromatic hydrocarbon (PAH) that is known as an environmental hormone that causes various cancers and causes mutations when accumulated in the human body. In 2006, the International Cancer Institute (IARC) Carcinogenic to humans (Group 1). The production of benzopyrene in food can be produced during the heating process of food, and when the food is cooked at high temperature or processed, the carbohydrates, proteins, fats, etc., which are the main components of the food, are produced by incomplete combustion.

Therefore, Korea Food and Drug Administration has been monitoring benzopyrene in food since 2001, and since benzopyrene was detected in olive oil in 2006, KFDA recommends benzopyrene in February 2007, the lowest level in the world, 2ppb. (1 in 1 billion) was established and managed. As a result of testing 104 edible oils in November 2006 and February 2007, benzopyrene (0.9 ~ 8.9ppb) was detected in 30 products, and in August 2007, 623 edible oils were marketed. As a result of monitoring, 47 products from 30 companies exceeded the recommended standard. From organic products, to large enterprise products to large marts, they were detected throughout the market for edible oils, with values up to eight times higher (15.92 ppb) of benzopyrene.

In addition, hplc (high-speed liquid chromatography), a benzopyrene tester, is expensive and difficult to equip in a small manufacturer, and has a problem in that it requires one-tenth of a billionth to inspect a skilled professional and an annual maintenance cost is too high.

Traditionally, sesame oil emphasizes taste, aroma and color, so it cannot go through the refining process after production like other edible oils and oils. However, the manufacturer expresses many difficulties in reducing and producing benzopyrene despite many process improvement and research. Development of benzopyrene stabilization technology is urgent.

The present invention has been invented to solve the existing problems as described above to peel the sesame seeds in order to reduce the generation of carbide which is the cause of benzopyrene in the production of sesame oil, inhibits the production of carbide, and forced exhaust in the roasting step Benzopyrene can be reduced by taking out the benzopyrene in the carbide and smoke, and it is possible to maintain the original taste and aroma of sesame oil even if it is roasted at low temperature without peeling because the sesame peels off the existing high risk of benzopyrene by roasting it at a high temperature. The aim is to provide consumers with safe and high-quality sesame oil by providing a sesame oil manufacturing method that minimizes the production of benzopyrene.

Benzopyrene reduced sesame oil production method using the peeling technology according to the present invention is called soaked sesame seeds in water for 30 minutes to 1 hour (CY100); A peeling step (CY200) of peeling the soaked sesame seeds by friction with water; Roasting the peeled sesame seeds to 90 ~ 100 ℃ drying step to remove the moisture and the skin by forced exhaust (CY300); Roasted exhaust step (CY400) to fry the dried sesame seeds at a temperature suitable for sesame oil to 100 ~ 180 ℃ to remove dust and smoke through forced exhaust; Cooling step (CY500) for preventing the temperature of the roasted sesame seeds continue to rise, characterized in that it comprises a milking step (CY600) for milking the cooled sesame seeds.

The present invention is to reduce the benzopyrene generated by roasting sesame seeds at a high temperature when producing sesame oil in the old way, peel off the shell carbonized at high temperature to minimize the generation of carbides, and forced exhaust of carbides It is a very useful invention that prevents the benzopyrene in smoke and carbides from sticking to sesame and stirs the sesame seeds at low temperature, while suppressing the occurrence of benzopyrene while maintaining the original taste and aroma.

<Description of the code for the main part>
CY100: soaking step CY200: peeling step CY300: drying step
CY400: roasting step CY500: cooling step CY600: milking step

Benzopyrene reduced sesame oil manufacturing method using the peeling technology of the present invention for achieving the same purpose as the effect of the present invention is called a sesame step (CY100), peeling peeling step (CYC200) as shown in the manufacturing process diagram of FIG. ), Drying the peeled sesame seeds with heat to remove the remaining husks, drying step (CY300), stir-frying the dried sesame seeds and exhausting smoke and carbide (CY400), lowering the temperature of the roasted sesame seeds Cooling step (CY500), the milking step (CY600) for milking the cooled sesame.

1. Soaking stage (CY100)

 In the soaking step (CY100), sesame seeds and foreign matters are raised by removing the sesame seeds and foreign matters by stirring them by putting sesame seeds in a mesh structure bucket and pouring water, and sand and dust are settled under the net. After soaking, leave it in water for 30 ~ 1 hours to separate the skin and sesame seeds.

The process called water is to make the separation between the shell and grain of sesame to make it easier to peel, and the sesame oil and twigs are mixed and roasted and milked, the taste of sesame oil is reduced, and in the roasting exhaust stage (CY400) More smoke may be generated to increase the benzopyrene content.

2. Peeling step (CY200)

Peeling step (CY200) is a step of taking out after turning sesame called water in the peeler to turn 100 ~ 1500rpm / min, 3 to 10 minutes to peel off the friction between each other.
Peeling too long by peeling due to friction between each other, or if the rotation is too fast, sesame raw material is also broken, the peeling yield worsens the drying step (CY300), stir exhaust stage (CY400), a lot of carbides in the cracking occurs in the benzopyrene It can occur a lot and yield decrease due to forced exhaust.

3. Drying Step (CY300)

Drying step (CY300) is to put the peeled sesame seeds in an electric stir-fryer heater temperature is 150 ~ 250 ℃ and when the temperature of the roasted peeled sesame seeds is 90 ~ 100 ℃ to take out.

The evaporation of moisture during drying and the peeling of the peeled off parts remove dust and smoke, which can be removed by forced exhaust to minimize benzopyrene generation.

4. Stir-fry stage (CY400)

 Stir-fry step (CY400) put dried peeled sesame seeds in an electric stir-fryer and set the heater temperature to 200 ℃ ~ 350 ℃ and stir-fry the peeled sesame seeds while discharging the carbides generated by moisture and crumbs with forced exhaust. If the temperature reaches 100 ℃ ~ 180 ℃, it is taken out.

The peeled sesame seeds are not roasted at high temperature, but the inherent taste and aroma of traditional sesame oil remain intact, but high temperature conditions that can generate benzopyrene do not occur and no carbides are generated. Peeled sesame without shells should be careful because the roasting temperature rises easily and the roasting time is short. In the case of the non-peeled sesame, it takes 20 to 25 minutes after washing, but the peeled sesame is shortened to 10 to 15 minutes, so it is an important step to lower the conditions of the roasting temperature and time that benzopyrene occurs.

5. Cooling stage (CY500)

The cooling step (CY500) is to cool down the roasted sesame seeds to prevent the sesame seeds from rising continuously due to self-heating and to control the temperature to the desired temperature of the customer.

Sesame seeds have a high fat content and tend to continue to rise due to their fat content.The fried sesame seeds are put in a cooler two or three times in a cooler and cooled by 20kg ~ 30kg per minute, Grain temperature should be cooled below 100 ℃ using a cooler that inhales the wind by forcing 13kg ~ 18kg of roasted sesame seeds.

6. Milking stage (CY600)

Milking step (CY600) is a step of squeezing the cooled sesame oil using a common milking machine, the milking machine is pressed to collect enough oil from the cooled sesame, the temperature of the milking machine is 80 ~ 100 ℃ and the pressure is Squeeze sesame oil from 550 to 600kgf / cm ² .

Since the milked sesame oil contains debris, it is preferable to carry out the refining process. The refining process may be carried out by a natural immersion, a housing (sieve) filter, a press filter, or a cartridge filter.

In the following examples, the sesame oil milked with sesame oil was peeled through several experiments to minimize the content of benzopyrene according to the present invention, and the benzopyrem content was investigated.
