Description

Perilla oil manufacturing method by sterilization and non-heating {Method for producing perilla oil by sterilization and non-heating}

The present invention relates to a method for producing perilla oil by sterilization and non-heating, and more particularly, by milking perilla oil without applying heat during milking, the component of perilla itself is not destroyed without damaging the components of perilla oil. It relates to a method of manufacturing perilla oil by sterilization and non-heating so that milking is achieved in a furnace.

In general, perilla is an annual herbaceous plant cultivated in various Asian countries, such as Korea, China, and Japan, and contains various useful ingredients, so it is used as a medicinal crop, oil crop, and leaf vegetable.

In other words, the seeds of perilla contain a large amount of linolenic acid, an omega-3 fatty acid, which inhibits the synthesis of eicosanoids that cause adult diseases such as hypertension and allergic diseases, and has bioregulatory functions such as improving learning ability and extending lifespan. It is known that the seed itself is sesame, which is used for perilla tea and confectionery, and the oil extracted from the seed is used for food, drug addition, and industrial use.

Perilla leaves, which are vegetable essential oils, contain perilla aldehyde, limonene, and perilla ketone, which have a unique fragrance. It is used as a vegetable, and the extract of perilla leaves is used as a cosmetic color or fragrance.

Moreover, recently, as it is known that tocopherol can prevent cardiovascular disease and cancer, support immune function, and prevent and alleviate aging-related degenerative diseases, the demand for perilla, one of the largest natural sources of tocopherol, is increasing. is increasing

Perilla oil, a vegetable oil, is manufactured from these perilla seeds, and along with sesame oil, it is one of the traditional edible oils in Korea. α-linolenic acid (C18:3), which belongs to the 3 series polyunsaturated fatty acids, accounts for around 60%.

Numerous research results have been published on the physiological functions of perilla oil with a high content of α-linolenic acid. Artificially induced colorectal cancer and breast cancer growth inhibition, improvement of learning ability, prevention of heart disease and blood clots due to lowering of platelet aggregation ability, and improvement of allergic constitution are attracting attention. It is an oil that plays an important role in maintaining the fatty acid balance.

Perilla oil obtained by roasting and pressing with a furnace has a unique fragrance, and the content and pattern of fragrance components vary depending on the roasting temperature.

The conventional method for producing perilla oil is washing with water to remove foreign substances and roasting hot air-dried perilla, then pulverizing the roasted perilla and pressing it in an milking machine. The higher the yield, the higher the extraction yield of perilla oil.

However, perilla oil is weak to heat, and in the conventional perilla oil manufacturing method, perilla oil is exposed to excessive heat and ultraviolet rays during the process of drying perilla with water after washing with water, roasting perilla, and milking using a thermocompression press. In the heat treatment process, for example, useful components of perilla such as omega 3 may be denatured, or carcinogens such as benzopyrene, which are harmful to health, may be generated in excess of the standard value, resulting in a problem of quality deterioration.

For example, Patent Document 1 below discloses a 'method for producing raw perilla oil'.

The method for producing raw perilla oil according to Patent Document 1 includes the steps of washing sesame seeds and precipitating them using a stone mill, and pressing the washed and crushed sesame seeds to milk raw perilla oil.

Hereinafter, a method for manufacturing perilla oil by sterilization and non-heating according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

<First embodiment>

The method for manufacturing perilla oil by sterilization and non-heating according to a first preferred embodiment of the present invention includes the steps of wearing harvested perilla (S110), and removing foreign substances and limestones ( S120), the step of sterilizing bacteria (or microorganisms) embedded in the perilla by ultraviolet light (S130), putting the ultraviolet sterilized perilla into the milking machine, and applying a predetermined pressure to prevent heat from being applied during milking. It includes a milking step (S140) of obtaining raw perilla oil from perilla, and a purification step (S150) of filtering foreign substances in the milked raw perilla oil.

The warehousing step (S110) of perilla is threshed in cultivated land and warehousing is carried out in a sack, and the raw material suitable for the standard of perilla to be used is used as well as checking the certificate of origin, etc. .

In the step of removing foreign substances and limestone (S120), perilla leaves or perilla stems contained in the sack are removed, as well as foreign substances such as stones, sand, and soil contained during harvesting of perilla.

Meanwhile, in the present invention, foreign substances refer to perilla leaves, perilla leaves, stones, sand, soil, etc. contained in the sack together with perilla, and will be expressed as “foreign substances and stones” for convenience of explanation.

The step of removing foreign substances and stones ( S120 ) may include a primary foreign material removal step of filtering out foreign substances and stones with a brush, and a secondary foreign material removing step of filtering foreign substances and stones with a mesh network.

It goes without saying that the perilla, which has undergone the step of removing foreign substances and limestone, is passed through a dry washing machine (not shown) to dry the perilla.

In the step of removing foreign substances and limestone (S120), foreign substances such as stones, sand, soil, etc. can be separately selected and removed by removing perilla leaves or perilla stems with a brush, and then passing perilla through a limestone remover (not shown).

As such, foreign substances and perilla that have undergone the limestone step are subjected to a sterilization process by an ultraviolet sterilizer (not shown) (S130).

In the sterilization step (S130), even if the perilla is harvested from cultivated land and put in a sack, it is to remove harmful bacteria (or microorganisms) in the raw material of perilla.

That is, ultraviolet sterilization is performed to remove microbiological harmful elements of perilla, and in the sterilization step (S130), enterohemorrhagic E. coli, Clostridium perpresence, Staphylococcus aureus, Bacillus cereus, Salmonella, Listeria monocytogenes , and sterilizes pathogenic microorganisms such as general bacteria and coliform group.

By irradiating ultraviolet rays of 200 to 280 nm for about 50 to 80 seconds in the ultraviolet sterilizer, it is possible to remove microbiological hazards of perilla.

Perilla, which has undergone the sterilization step (S130), is supplied to a milking machine, and milking is performed by the milking machine (not shown) (S140).

In this milking step, perilla is put into the hollow formed in the milking machine, and then the press installed on the upper part of the milking machine is lowered to an appropriate pressure, so that the perilla is squeezed and raw perilla oil is milked.

At this time, the press is pressed for 5-7 minutes from 0kg·f/cm3 to 600kg·f/cm3 after adding perilla, and then presses it for 10-20 minutes while maintaining 600kg·f/cm3.

That is, when pressurizing the press, it starts at a relatively low pressure at the beginning and gradually increases the pressure to 600 kg·f/cm 3 .

This is to increase the productivity of perilla oil from perilla by gradually increasing the pressure applied to the perilla input into the milking machine so that the perilla is compressed with a uniform pressure.

In addition, by pressurizing perilla at 600kg·f/cm3 for 10 minutes or more, enough time for milking is ensured so that milking can be performed more smoothly. That is, in the case of less than 10 minutes, the perilla oil from perilla may remain in a residual state, and in the case of pressurization for more than 20 minutes, the productivity decreases according to the working time.

The perilla oil milked in the milking machine is subjected to a refining step (S150) of passing through a mesh network.

As such, the method for producing perilla oil by sterilization and non-heating according to the first embodiment of the present invention can reduce the working time according to washing as perillas are not washed with water, as well as drying perillas more quickly by a dry washer. Therefore, it is possible to significantly reduce the working time due to the drying of perilla.

In addition, as bacteria or pathogenic microorganisms contained in perilla are removed and then milked, raw perilla oil that is safer for drinking can be prepared. It is possible to milk raw perilla oil in its pure form without destroying it.

The refining step (S150) consists of a first refining step (S152) by a mesh network, a second refining step (S154) of purifying the precipitate by natural precipitation, and a third refining step (S154) by a filter press .

In the first refining step (S152) of the refining step (S150), foreign substances contained in the milked raw perilla oil are filtered out by a mesh network. This will filter out particulate foreign substances contained in raw perilla oil.

In the second purification step (S154), the milked raw perilla oil is precipitated for a certain period of time or longer. By this secondary purification step (S154), the sediment contained in the raw perilla oil is settled.

This is to remove fine particles of foreign substances together with oil (or oil) during milking of raw perilla oil, and as the raw perilla oil (oil) is stored in the tank for a certain period of time or more, the sediment contained in the oil sinks.

It is purified by natural precipitation for about 12 to 36 hours so that these precipitates can sink.

The raw perilla oil on which the secondary purification has been made is subjected to a tertiary purification step by a filter press (not shown) (S156).

The raw perilla oil is put into the filter press, and then particles of about 1 micrometer or more are removed by compression of the filter press.

In this way, particulate foreign substances of 500 mesh or more are removed by primary refining (S152), particulate foreign substances contained in raw perilla oil are filtered by natural precipitation, and fine particulate foreign substances contained in raw perilla oil are removed by filter press. This makes it possible to refine (manufacture) into pure raw perilla oil.

The raw perilla oil that has undergone the refining step (S150) is stored in a large amount in a tank having a certain size (S160).

As such, the raw perilla oil produced by the second embodiment of the present invention can be sanitarily manufactured safer by removing pathogenic microorganisms harmful to the human body while going through the sterilization step (S120), and in the purification step (S150) It is possible to manufacture more transparent and clear raw perilla oil by removing particulate foreign substances and deposits contained in the milked raw perilla oil.
