Abstract
Description
본 발명은 식물의 생장시에 발생되는 에틸렌 가스의 생합성을 억제하여 채소 과일 등의 신선도를 유지하여 유통기한을 연장시킬 수 있는 원적외선의 조성물에 관한 것으로, 특히 포장용 비닐시트나 포장이나 저장용 용기 등에 적용이 가능한 것이다.The present invention relates to a far-infrared composition which can extend the shelf life by suppressing the biosynthesis of ethylene gas generated during plant growth and maintaining freshness of vegetables and fruits. It is applicable.
식물체에서 합성되는 에틸렌이 식물의 노화를 촉진시킨다는 것이 최근의 연구결과로 알려지게 된 것이다.It is known from recent research that ethylene synthesized in plants promotes aging of plants.
따라서 이러한 에틸렌이 식물에서 생합성되는 경로 또한 알려지게 되면서 그에 따른 에틸렌의 생성을 억제하는 억제제 또한 개발되기에 이른 것이다.Therefore, the path through which ethylene is biosynthesized in plants is also known, and thus inhibitors for inhibiting ethylene production have been developed.
그러나 이러한 억제제가 인체에 유해하고 억제제의 사용에 따른 수많은 문제점이 노출되어지는 것이다.However, these inhibitors are harmful to the human body and a number of problems due to the use of the inhibitors are exposed.
현재 알려진 에틸렌이 생합성되는 경로로는 methionine 물질이 전구물질로서 이는 AdoMet(S-adenosy1 methionine)으로 전환되고, AdoMet은 ACC synthase에 의하여 ACC(1-aminocyclopropane-1-1carboxylic acid)로, ACC는 ACC oxidase에 의하여 에틸렌으로 전환되는 것이다.Currently known ethylene biosynthesis pathway is a methionine precursor, which is converted to AdoMet (S-adenosy1 methionine), AdoMet is ACC (1-aminocyclopropane-1-1carboxylic acid) by ACC synthase, ACC is ACC oxidase Is converted to ethylene.
따라서 이러한 에틸렌은 생장과 직접적인 관련이 있는 DNA합성을 억제하기 때문에 식물의 노화 즉 신선도의 유지가 장시간 이루어지지 않게 되는 것이다.Therefore, such ethylene inhibits DNA synthesis, which is directly related to growth, and thus prevents aging of plants, that is, maintaining freshness for a long time.
따라서 최근에는 특정한 억제제에 의하여 상기와 같은 현상을 방지하고 있다고 하나 이러한 억제제의 사용이 예를 들면 각각의 단계별로 특정되어지는 억제제가 사용되고 있는 것이고, 이러한 억제제의 일종인 AVG(aminoethoxyvinylglycine)는 AdoMet가 ACC로 전환되는 단계를 특이하게 억제하게 되는 것이고, cobalt ion은 ACC가 에틸렌으로 전환되는 것을 억제한다고 알려져 있는 것이다.Therefore, in recent years, such inhibitors are prevented by specific inhibitors, but the use of such inhibitors is being used, for example, for each step. An inhibitor of such inhibitors, AVG (aminoethoxyvinylglycine), is one of AdoMet's ACC. It specifically inhibits the step of converting to cobalt ions and is known to inhibit the conversion of ACC to ethylene.
그러나 이러한 억제제들이 인체에 유해하거나 처리비용으로 인하여 사용이 극히 제한되고 있는 실정이다.However, these inhibitors are harmful to the human body or due to the treatment costs are extremely limited use.
따라서 본 발명은 고분자화합물의 고유 흡수파장과 같은 파장대를 갖는 원적외선을 이용하여 포장을 위한 비닐시트나 용기 등에 적용토록 함으로서 원전외선이 생체에 흡수되면서 세포의 물분자와 공진현상을 일으키면서 신선도의 유지로 인하여 저장성을 유지토록 한 것이다.Therefore, the present invention is applied to a plastic sheet or a container for packaging using far infrared rays having the same wavelength band as the intrinsic absorption wavelength of the polymer compound, so that the nuclear energy is absorbed into the living body and maintains the freshness while resonating with the water molecules of the cells. This is to maintain storage.
도 1은 본 발명의 실험을 위한 일 실시 예의 개략도.1 is a schematic diagram of one embodiment for an experiment of the present invention.
<도면의주요부분에대한부호의설명>Explanation of symbols on the main parts of the drawing
1: 바이알 2: 실리콘 캡1: vial 2: silicone cap
3: 하배축조직 4: 알루미늄 호일3: hypocotyl 4: aluminum foil
이하 다음의 일 실시 예에 의거 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the following examples.
우선 원적외선은 고분자화합물의 고유 흡수파장과 같은 파장대에 있기 때문에 생체에 잘 흡수되어 세포의 물분자와 공진현상을 일으켜 세포의 활성화가 유도됨으로 신선도의 유지가 장시간 가능하게 되는 것이다.First, since the far infrared rays are in the same wavelength band as the inherent absorption wavelength of the polymer compound, they are well absorbed by the living body, causing resonance with the water molecules of the cell, leading to activation of the cell, and thus maintaining freshness for a long time.
따라서 원적외선에 적당량 함유될 경우에는 포장의 형태에 따라 또는 생물에 따라 신선도의 유지가 장시간 가능한 것이다.Therefore, in the case of containing an appropriate amount in the far infrared, it is possible to maintain the freshness for a long time depending on the form of the package or the organism.
이를 위하여 본 발명에서는 실험의 대상으로 녹두 하배축(4)의 절편에서 대조군에 의한 에틸렌의 생성여부를 확인하였고 본 발명의 세라믹스 원료의 성분과 구성광물을 다양한 방법으로 분석하고 원적외선 방사특성을 분석하였다.To this end, the present invention confirmed whether the ethylene produced by the control in the segment of the mung bean hypocotyl (4) as the subject of the experiment, and analyzed the components and constituent minerals of the ceramic raw material of the present invention by various methods and analyzed the far-infrared radiation characteristics.
또한 각각의 세라믹스와 세라믹스를 첨가한 우레탄 수지가 식물에서의 노화에 관여하는 에틸렌 생성에 미치는 영향을 분석함으로서 본 발명의 목적을 달성토록 한 것이다.In addition, the object of the present invention is achieved by analyzing the effect of the ceramics and the urethane resin containing the ceramics on ethylene production involved in aging in plants.
그 결과 원적외선 세라믹스는 녹두 하배축 조직에서의 에틸렌 생성을 억제하였고, 이러한 효과는 다음의 각각의 실시 예에서 우수함을 나타냈으며 특히 원료 형태 즉 분말, 디스크(disk), 입자(pellet) 등 세라믹스의 적용 형태에 따라 에틸렌 억제 작용에는 차이가 있었고, 동시에 세라믹스 분말을 첨가한 우레탄 수지를 적용한 경우에도 에틸렌 생성을 효과적으로 억제하였다.As a result, the far-infrared ceramics suppressed the ethylene production in the mung bean hypocotyl structure, and this effect was shown to be excellent in each of the following examples. In particular, the application form of the ceramics such as powder, disk, and pellets There was a difference in the ethylene suppression effect, and at the same time, ethylene production was effectively suppressed even when a urethane resin containing ceramic powder was applied.
본 발명에서는 다음의 실시 예에 나타낸 바와 같이 천연 규산염 광물을 원료로 사용하였으며, 각각의 원료는 SEM/EDS를 이용하여 성분을 분석하였으며 XRD를 이용하여 구성광물의 결정상을 분석하였다.In the present invention, as shown in the following examples, natural silicate minerals were used as raw materials. Each raw material was analyzed by SEM / EDS, and the crystal phase of the constituent minerals was analyzed by XRD.
그리고 천연 원료 분말과 각각의 원료를 1000℃에서 1시간 동안 하소한 후 재 분쇄하여 FT-IR을 이용하여 40℃에서 원적외선 방사 특성을 측정하였다.The raw material powder and each raw material were calcined at 1000 ° C. for 1 hour and then regrind to measure far-infrared radiation characteristics at 40 ° C. using FT-IR.
그 결과 식물의 신선도 유지 및 수명 연장 효과는 식물에서 생상되는 에틸렌의 양을 측정하여 비교할 수 있었다.As a result, the freshness and life extension effects of plants could be compared by measuring the amount of ethylene produced in the plants.
본 발명에서 사용된 녹두의 하배축 조직은 원료에 의한 에틸렌의 흡착을 배제하고 원료(세라믹스)에서 방사되는 원적외선의 효과만을 측정하기 위하여 도1에 도시된 바와 같이 녹두 하배축(3) 조직을 바이알(vial)(1)에 넣고 실리콘 고무마개(2)로 밀폐한 후 바이알(1)을 세라믹스 분말로 외부에서 감싸게 하였으며 각 바이알은 알루미늄 호일(A1-foil)(4)을 이용하여 분리하여 서로 영향을 받지 않게 하였다.The hypocotyl tissue of the mung bean used in the present invention is a vial of the mung bean hypocotyl (3) tissue as shown in FIG. 1 in order to exclude the adsorption of ethylene by the raw material and to measure only the effect of far infrared rays emitted from the raw material (ceramic). (1) and sealed with a silicone rubber stopper (2) to wrap the vials (1) from the outside with ceramic powder. Each vial is separated using aluminum foil (A1-foil) (4) and is not affected by each other. It was not.
또한 세라믹스의 형태에 따른 효과를 측정하기 위해서는 실시 예 1의 원료를 입자(pellet)형태로 소성하였고, 이때 소성온도와 시간은 1200℃, 1시간이었다.In addition, in order to measure the effect according to the shape of the ceramics, the raw material of Example 1 was fired in the form of pellets, wherein the firing temperature and time were 1200 ° C. for 1 hour.
또한 에틸렌 생성량은 주사기를 이용하여 바이알(vial)내의 기체를 채취하여 Gas Chromatography를 이용하여 측정하였다.In addition, the amount of ethylene produced was measured by Gas Chromatography by collecting the gas in the vial (vial) using a syringe.
또한 원적외선 세라믹스를 첨가한 우레탄 수지의 신선도 유지 및 수명연장 효과를 측정하기 위해서는 실제 채소류의 포장시 포장지와 채소가 접촉하므로 바이알내에 녹두 하배축조직과 세라믹스를 첨가한 우레탄 수지를 함께 넣어 측정하였다.In addition, in order to measure the freshness and life extension effect of the urethane resin containing far-infrared ceramics, the packaging paper and the vegetable contacted the actual vegetable packaging, so the mung bean hypocotyl and the urethane resin containing ceramics were put together in the vial.
다음은 세라믹스 원료의 배합비율을 100분율로 나타낸 일 실시 예이다.The following is an embodiment in which the blending ratio of the ceramic raw material is represented as 100 parts.

상기의 각각의 실시 예에 사용한 각 원료(세라믹스)에 대한 EDS를 이용한 성분 분석 성분비를 보면 실시 예1과 2는 SiO2,Al2O3가 주성분이었으며 실시 예3은 SiO2,Al2O3,Fe2O3, 가 주성분이었고, 실시 예4는 SiO2,Fe2O3,MgO 등이 주성분이었다.Component analysis using EDS for each raw material (ceramic) used in each of the above Examples 1 and 2 were SiO 2, Al 2 O 3 was the main component and Example 3 was SiO 2, Al 2 O 3 , Fe 2 O 3 , was the main component, and Example 4 was SiO 2, Fe 2 O 3, MgO and the like.
또한 본 발명에서 원료(세라믹스)에 대한 XRD를 이용하여 분석한 구성 결정상에 대하여 실시 예1과 2는 주로 illite광물과 quartz로 구성되어 있었고, 실시 예3에서는 quartz와 함께 orthoclase가 포함되어 있었고, 실시 예4에서는 quartz와함께 vermiculite, actinolite, talc, tremolite 등의 광물로 구성되어 있었다.In addition, Examples 1 and 2 mainly consisted of illite minerals and quartz, and in Example 3, containing orthoclase together with quartz, for the constituent crystal phases analyzed using XRD on the raw material (ceramic) in the present invention. Example 4 consisted of minerals such as vermiculite, actinolite, talc and tremolite with quartz.
또한 본 발명에서는 식물의 신선도 유지가 목적이므로 방사율 측정이 가능한 최저온도인 40℃에서 FT-IR spectrometer를 이용하여 5~20㎛ 범위에서 Black Body 대비 측정하였다.In addition, in the present invention, the purpose of maintaining the freshness of the plant was measured in comparison with the black body in the range of 5 ~ 20㎛ using an FT-IR spectrometer at 40 ℃, the lowest temperature that can measure the emissivity.
다음의 그림에서는 실시 예 1,2,3,4에 대한 원적외선 방사 특성을 흑체에 대한 원적외선 방사강도와 분광 방사율로 나타낸 것이다.In the following figure, the far-infrared radiation characteristics of Examples 1, 2, 3, and 4 are shown in terms of far-infrared radiation intensity and spectral emissivity for black bodies.
즉 본 발명의 세라믹스 원료의 5~20㎛ 범위에서의 평균 방사율이 실시 예1에서는 92.2%, 실시 예2에서는 92.3%, 실시 예3에서는 92.7%, 실시 예4에서는 92.3%이었다.That is, the average emissivity of the ceramic raw material of the present invention in the range of 5 to 20 µm was 92.2% in Example 1, 92.3% in Example 2, 92.7% in Example 3, and 92.3% in Example 4.
그러나 원료를 1000℃에서 1시간 동안 하소하였을 때 원적외선 방사율은 더 높아졌다.However, far-infrared emissivity was higher when the raw material was calcined at 1000 ° C. for 1 hour.
또한 하소하지 않은 세라믹스를 도2에 도시된 바와 같이 녹두 하배축 조직이 들어 있는 바이알의 외부에 두고 이 때에 녹두하배축 조직에서 생성되는 에틸렌을 측정하였다.In addition, as shown in FIG. 2, the ceramics that were not calcined were placed outside the vial containing the mung bean hypocotyl tissue, and ethylene produced in the mung bean hypocotyl tissue was then measured.
이때 세라믹스의 분말이 직접 녹두 하배축에 접하는 것이 아니라 바이알 외부에 있기 때문에 원적외선의 직접적인 효과를 확인 할 수 있는 것이다.At this time, since the powder of ceramics is not directly in contact with the mung bean hypocotyl but is outside the vial, the direct effect of far infrared rays can be confirmed.
또한 에틸렌 생성을 유도하기 위하여 식물 호르몬의 일종인 IAA를 동시에 처리하였고, 시간의 경과에 따른 에틸렌 생성량을 비교하였다.In addition, in order to induce ethylene production, IAA, which is a kind of plant hormone, was simultaneously treated, and ethylene production was compared with time.
그 결과 2시간이 경과하였을 경우에 실시 예1과 4는 대조군와 비슷한 에틸렌을 생성하였고, 실시 예2와 3은 대조군와 비교하여 약간 증가된 에틸렌 생성을 나타내었다.As a result, when 2 hours elapsed, Examples 1 and 4 produced ethylene similar to the control, and Examples 2 and 3 showed slightly increased ethylene production compared to the control.
그러나 8시간이 경화 한 후에는 세라믹스의 모든 종류가 대조구와 비교하여녹두하배축 조직에서 에틸렌 생성을 약 40%정도 억제하였다.However, after 8 hours of curing, all kinds of ceramics inhibited ethylene production by 40% compared to the control group.
이를 시간에 따른 에틸렌 생성량의 변화는 다음의 그림에 나타내었다.The change in ethylene production over time is shown in the following figure.
그 결과 실시 예1이 실시 예2와 3 보다는 에틸렌 억제 효과가 뛰어났고, 실시 예4와는 유사한 효과를 나타내었다.As a result, Example 1 was more effective in inhibiting ethylene than Examples 2 and 3, and showed a similar effect to Example 4.
이러한 결과를 바탕으로 소성 전 세라믹스도 어느 정도 에틸렌 생성 억제 효과를 나타내는 것을 알 수 있었다.Based on these results, it was found that the ceramics before firing also exhibited an effect of inhibiting ethylene production to some extent.
또한 1000℃에서 1시간동안 하소한 세라믹스를 녹두 하배축 조직이 들어 있는 바이알의 외부에 두고 녹두하배축 조직에서 생성되는 에틸렌을 측정하였다.In addition, the ceramics calcined at 1000 ° C. for 1 hour were placed outside the vial containing the mung bean hypocotyl tissue, and ethylene produced in the mung bean hypocotyl tissue was measured.
이때 에틸렌 생성을 유도하기 위하여 식물 호르몬의 일종인 IAA를 동시에 처리하였고, 시간의 경과에 따른 에틸렌의 생성량을 비교하였다.At this time, in order to induce the production of ethylene, IAA, a kind of plant hormone, was simultaneously treated, and the amount of ethylene production was compared with time.
그 결과 2시간이 경과 한 뒤에 실시 예1과 4는 대조구와 비슷한 에틸렌을 생성하였고, 실시 예2와 3은 대조구와 비교하여 약간 억제된 에틸렌 생성을 나타내었다.As a result, after 2 hours, Examples 1 and 4 produced ethylene similar to the control, and Examples 2 and 3 showed slightly suppressed ethylene production compared to the control.
또한 8시간이 경과 한 후의 결과에서 보면 각 세라믹스가 처리된 모든 실험구에서 대조구와 비교하여 에틸렌 생성량이 약간 억제된 것을 볼 수 있었다.In addition, the results after 8 hours showed that the amount of ethylene produced was slightly suppressed compared to the control in all the experimental groups treated with each ceramic.
따라서 시간에 따른 에틸렌 생성량의 변화를 살펴보면, 실시 예2와 실시 예3은 에틸렌 생성 억제 효과를 나타내었으며, 실시 예1은 크게 효과를 나타내지는 않았고 실시 예 4는 오히려 에틸렌 생성을 증가시키는 작용을 나타내었다.Therefore, looking at the change in the amount of ethylene produced over time, Example 2 and Example 3 showed the effect of inhibiting the ethylene production, Example 1 did not show a significant effect, Example 4 shows the action to increase the ethylene production rather It was.
따라서 하소한 세라믹스도 어느 정도 에틸렌 생성 억제 효과를 나타내는 것을 알 수 있었다.Thus, it was found that calcined ceramics also exhibit some degree of ethylene production suppression effect.
또한 에틸렌 생성 억제 효과가 있는 실시 예1을 디스크형태와 입자 형태로 만들어져 에틸렌 생성에 어떠한 영향을 미치는지 확인한 결과 시간에 다른 에틸렌 생성량의 변화를 살펴보면, 2시간이 경과한 뒤에 에틸렌 생성을 억제하였고, 24시간이 지난뒤에 살펴보면, 그 억제 효과는 더 나타나서 입자 형태인 경우에 25%의 억제 효과를 나타내었다.In addition, as a result of confirming the effect of Example 1 having the effect of inhibiting ethylene production in the form of disk and particles, the effect of ethylene production was different. Looking after time, the inhibitory effect was further revealed, showing a 25% inhibitory effect in the form of particles.
또한 각각의 실시 예에 우레탄 수지에 첨가하여 실제로 응용할 수 있는 가능성을 조사하였다.In addition, the possibility of practical application by adding to urethane resin in each Example was investigated.
실험시간도 24시간으로 늘려 실용성인 측면에 중점을 두어 실험을 하였다.The experiment time was also increased to 24 hours, focusing on practical aspects.
그 결과 2시간이 경과 한 뒤에는 세라믹스가 첨가된 우레탄 수지와 함께 들어 있던 녹두 하배축에서 에틸렌 생성이 촉진되는 경향을 보였으나 24시간이 지난 뒤에는 세라믹스가 첨가된 우레탄 수지가 에틸렌 생성을 50%정도로 현저하게 억제하였다.As a result, after 2 hours, the ethylene production tended to be accelerated in mung bean hypocotyl containing ceramics added urethane resin, but after 24 hours, ceramics added urethane resin produced 50% ethylene production. Suppressed.
즉, 세라믹스 분말을 우레탄 수지에 첨가하였을 때 에틸렌 생성을 억제하는효과가 나타났으며, 오히려 억제 효과가 더 좋았다.That is, when the ceramic powder was added to the urethane resin, the effect of inhibiting ethylene production appeared, and rather, the inhibitory effect was better.
따라서 원료와 합성수지의 배합비율은 다음과 같이 한 것이다.Therefore, the mixing ratio of the raw material and the synthetic resin is as follows.
실시 예 5Example 5
Al2O318.78-21.22 %Al 2 O 3 18.78-21.22%
SiO249.97-58.12 %SiO 2 49.97-58.12%
K2O 4.18-5.12 %K 2 O 4.18-5.12%
TiO21.11-1.94 %TiO 2 1.11-1.94%
MgO 1.00-1.18 %MgO 1.00-1.18%
Fe2O315.88-21.60 %Fe 2 O 3 15.88-21.60%
합성수지 500-950 %Synthetic resin 500-950%
본 발명에서의 합성수지의 비율은 원료가 많이 함유될수록 우수한 효과를 나타내는 것이나 통상적으로 사출조건에 따라 달라지게 되나 통상 비닐지로서의 성형을 위하여는 성형된 후 인장시에 틋어짐이 없도록 하여야 하는 것이다.The ratio of the synthetic resin in the present invention is to exhibit an excellent effect as the raw material is contained, but usually depends on the injection conditions, but in order to form as a normal plastic paper, it is to be such that there is no break at the time of stretching after molding.
이를 위하여는 통상 합성수지를 중량대비하여 100으로 할 경우에 원료의 비율이 2%에서 50%까지가 가장 적합한 것이고, 그 이상이 될 경우에는 인장시에 틋어짐이 발생하게 되는 것이다.For this purpose, the ratio of the raw material is usually 2% to 50% is most suitable when the synthetic resin is set to 100 by weight, and when it is more than that, the tensile strength occurs.
또한 원료를 합성수지 대비하여 2%미만을 사용할 경우에는 원료의 미소량으로 원적외선에 의한 본 발명의 목적을 달성할 수 없는 것이고, 이러한 비율은 사용조건에 따라 적절하게 배합하여 사용되는 것이다.In addition, when less than 2% of the raw material is used compared to the synthetic resin, it is impossible to achieve the object of the present invention by far infrared rays with a small amount of the raw material, and such a ratio is suitably used according to the conditions of use.
본 발명에 따르면, 실제 숙주나물이나 콩나물과 같은 두 채류의 포장재로 세라믹스가 첨가된 수지를 사용하면 그 유통기한이 증가할 가능성을 제시하고 있다. 또한 세라믹스의 형태에 따른 효과를 더 연구하여 포장재 이외의 용도로 사용할 수 있는 가능성을 제시하고 있다.According to the present invention, the shelf life of the resin added with ceramics as a packaging material for two vegetables such as bean sprouts and bean sprouts is increased. In addition, by studying the effect of the shape of the ceramics further suggests the possibility to use for applications other than packaging materials.
