Description
본 발명은 식품포장용 가스 흡착수지 조성물에 관한 것으로, 특히 야채, 과일, 어류와 육류 등의 식품의 저장, 유통 및 전시 판매하는 동안에 발생되는 에틸렌, 아민, 암모니아, 초산 등과 같은 가스를 흡착제거하여 식품의 신선도를 유지하여 구매가치를 높일 수 있도록 하는 식품포장용 가스 흡착 수지조성물 및 그러한 가스 흡착 수지조성물로 만든 포장지나 용기와 같은 제품에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas adsorption resin composition for food packaging, and more particularly, to adsorption and removal of gases such as ethylene, amine, ammonia, acetic acid, etc. generated during the storage, distribution and exhibition of foods such as vegetables, fruits, fish and meat. The present invention relates to a gas adsorption resin composition for food packaging and a package or container made from such a gas adsorption resin composition to maintain freshness and to increase purchase value.
최근 소비자의 소비 형태는 핵가족화, 여성인구의 취업증가, 소득수준의 증가, 인구의 노령화, 건강에 대한 관심의 제고 등과 같은 사회 환경 변화와 함께 소비자들은 보다 안전하고 품질이 좋으면서 구매가 편리한 식품을 선호하는 추세에 있으며, 이에 맞추어 식품을 소량으로 포장하여 유통하는 것이 요구되고 있다.Recently, consumers' consumption patterns are foods that are safer, higher quality and more convenient to buy, along with changes in the social environment such as nuclear family, increase in employment of female population, increase in income level, aging population, and increased interest in health. There is a trend to prefer, it is required to package and distribute the food in small quantities accordingly.
특히, 소비자들의 식품 환경에 대한 관심의 증가로 환경호르몬 등 유해화학물질과 관련하여 식품이나 농산물의 생산 관리에 대해서 보다 적극적으로 관심을 표명하게 되었을 뿐만 아니라, 제품 구매시 외관의 상태, 보관 및 유통을 위한 포장의 안전성과 합리성 등에 대해서도 매우 높은 관심을 갖게 되었다. In particular, as consumers' interest in the food environment has increased, they have expressed more interest in the production and management of food and agricultural products in connection with hazardous chemicals such as environmental hormones. There is also a very high interest in the safety and rationality of the packaging.
이에 부응하기 위한 업계의 노력으로 식품의 유통, 보관 및 전시 판매를 위한 포장기술 및 포장재료에서 많은 발전과 성장을 이루어왔다.In response, the industry has made great progress in packaging technology and packaging materials for the distribution, storage and exhibition of food.
식품의 포장에 있어서 주로 폴리프로필렌이나 폴리에틸렌 등과 같은 합성수지를 많이 사용하고 있으며, 포장 재료에 대한 연구 노력으로 이들 합성수지 포장재의 일부는 통상 산소는 투과시키고 수분은 차단할 수 있도록 개선함으로써 포장지 또는 포장용기에 수용된 상태로 판매 및 유통되는 과채류 신선도를 높이도록 하고 있다.In the packaging of food, synthetic resins such as polypropylene and polyethylene are used a lot, and research efforts on packaging materials are generally used to improve some of these synthetic resin packaging materials to permeate oxygen and block moisture. It aims to increase the freshness of fruits and vegetables sold and distributed in the state.
그런데, 수확된 과채류 및 과실은 동화작용의 기능을 상실하고 호흡작용에 의해 전분, 유기산, 당 등의 저장물질을 소모하게 되며, 이때의 호흡은 온도가 높고 에틸렌 농도가 높은 조건에서 왕성하게 된다. 에틸렌은 과채류의 저장 중에 발산되는 천연호르몬으로서 과채류의 호흡을 상승시키고 과숙을 촉진시킨다. However, the harvested fruits and vegetables lose the function of assimilation and consume the storage materials such as starch, organic acids and sugars by respiration, and the respiration is vigorous under high temperature and high ethylene concentration. Ethylene is a natural hormone released during storage of fruits and vegetables that promotes respiration and promotes fruiting.
에틸렌 발생량을 저감시키기 위해서는 포장용기 내부의 온도를 낮추고 산소를 차단하거나 발생하는 에틸렌 가스를 흡착하여 제거해야 하는데 비교적 고가의 산소 투과 합성수지 필름 혹은 발포제로는 에틸렌 가스의 제거가 불가능하며 오히려 밀폐된 경우에는 박스 내의 에틸렌 가스농도가 증가하게 되어 과숙이 촉진될 수도 있는 문제가 발생된다.In order to reduce the amount of ethylene generated, the temperature inside the packaging container must be lowered, the oxygen is blocked, or the ethylene gas generated by adsorption is removed by adsorption. The relatively expensive oxygen permeable synthetic film or blowing agent cannot remove the ethylene gas, but rather it is sealed. The problem is that ethylene gas concentrations in the box will increase, which may promote overgrowth.
과채류와 달리 생선이나 육류의 경우는 비린내와 같은 아민 화합물에서 유래되는 냄새가 발생되고, 이로 인하여 실제보다 덜 신선하게 느끼는 경우가 많은데 통상의 합성수지 포장 재료로는 이러한 육류나 생선에서 발생되는 냄새를 저감할 수 없는 문제점이 있었다. Unlike fruits and vegetables, fish and meat produce odors derived from amine compounds such as fishy smells, which often make them feel fresher than they actually are. There was a problem that could not be.
본 발명의 목적은 종래 과채류의 유통 및 판매 중에 과채류의 호흡시 발생되는 에틸렌으로 인한 과숙의 문제점과 육류 및 생선에서 발생되는 냄새의 문제점을 해결하기 위한 것으로, 과채류의 과숙을 유발하는 에틸렌과 생선이나 육류에서 발생되는 아민, 암모니아, 초산 등과 같은 냄새 유발 가스를 흡착제거하고 미생물에 의한 부패를 방지하여 식품의 신선도를 유지하고 식품의 유통 보관 기간의 연장 및 구매가치를 향상시킬 수 있는 식품포장용 가스 흡착 수지조성물을 제공하는 것이다.An object of the present invention is to solve the problem of over-maturation caused by ethylene generated when breathing fruit vegetables during the distribution and sale of fruits and vegetables, and the smell of meat and fish. Adsorption of odor-inducing gases such as amines, ammonia, acetic acid, etc. from meat, and adsorption of food packaging gases that can prevent food decay by microorganisms, maintain food freshness, extend shelf life of food, and improve purchase value It is to provide a resin composition.
본 발명의 다른 목적은 상기한 식품 포장용 가스 흡착 수지조성물로 형성된 포장지와 포장용기와 같은 가스 흡착 수지 성형물을 제공하는 것이다.Another object of the present invention is to provide a gas-adsorbing resin molded article such as a wrapping paper and a packaging container formed of the gas-adsorbing resin composition for food packaging.
상기한 본 발명의 목적은, 폴리에틸렌, 폴리프로필렌 및, 폴리에틸렌테레프탈레이트로 이루어지는 군(群)으로부터 선택되는 1종의 합성수지 80~90중량%와; 산화 티타늄, 탄산칼슘, 활성탄, 맥반석, 제올라이트, 칠보석 및, 게르마늄으로 이루어지는 군으로부터 선택되는 적어도 2종의 120~150 메시 크기를 가지며 에틸렌 흡착량 302~786 ㎕/kg 및 암모니아 흡착량 150~483㎕/kg인 분말상 다공성 및 이온성 가스 흡착성 물질 10~20중량%로 구성되는 가스 흡착 수지조성물 펠릿을 사출 성형하여 형성되는 가스 흡착성 식품포장재에 의하여 원활히 달성될 수 있다.The object of the present invention described above is 80 to 90% by weight of one kind of synthetic resin selected from the group consisting of polyethylene, polypropylene and polyethylene terephthalate; At least two 120-150 mesh sizes selected from the group consisting of titanium oxide, calcium carbonate, activated carbon, elvan, zeolite, seven-stone and germanium, with adsorption amount of 302-786 μl / kg and ammonia absorption of 150-483 The gas-adsorbable food packaging material formed by injection molding a gas-adsorbing resin composition pellet composed of 10 to 20% by weight of powdery porous and ionic gas-adsorbent material having a μl / kg can be smoothly achieved.
본 발명에 의한 가스 흡착제를 포함하는 수지조성물로 형성된 포장용기나 포장 필름은 과채류 및 과실의 호흡작용으로 발생하는 에틸렌가스, 탄산가스 등을 흡착제거하고 미생물에 의한 부패를 방지하여 과채류의 신선도를 유지함과 동시에 생선이나 육류의 선별적인 탈취작용에 의해 상품의 구매가치를 높이게 되므로 소비자의 구매 욕구를 높이고 결과적으로 제품의 부가가치가 높아진다. Packaging containers or packaging films formed of a resin composition containing a gas adsorbent according to the present invention adsorption and removal of ethylene gas, carbon dioxide gas generated by the fruit and fruit respiratory action and to prevent corruption by microorganisms to maintain the freshness of fruits and vegetables At the same time, the purchase value of the product is increased by the selective deodorization of fish or meat, which increases the consumer's desire to purchase and consequently increases the value added of the product.
이하에서는 본 발명의 실시예를 통하여 본 발명을 보다 구체적으로 설명하기로 한다.Hereinafter, the present invention will be described in more detail with reference to the following examples.
본 발명의 식품포장용 가스 흡착용 수지조성물은 a) 합성수지 80～99중량%와 가스 흡착을 위한 기능성 물질로서 b)가스 흡착성 물질 1～20중량%로 이루어진다. 이때, 수지에 대한 가스 흡착성 물질의 혼입 비율이 1중량% 보다 적으면 가스 흡착성능을 기대하기 어렵고 20중량% 보다 크면 조성물로 성형가공이 어려우므로 1～20중량%가 바람직하다. 상기 가스흡착성 물질은 흡착제로서 산화 티타늄, 탄산 칼슘, 활성탄, 맥반석, 제올라이트, 칠보석, 게르마늄 중에서 선택된 적어도 하나의 물질로 80～200 메시(mesh), 바람직하기로는 120～150 메시의 분말 형태이다. 이때, 가스흡착제의 입자가 80 메시 보다 큰 경우에는 수지와 혼합되기 어렵고 200 메시 보다 작은 경우에는 제조비용이 증가하는 단점이 있다. The resin composition for gas adsorption for food packaging of the present invention comprises a) 80 to 99% by weight of synthetic resin and b) 1 to 20% by weight of gas adsorbent as functional material for gas adsorption. At this time, when the mixing ratio of the gas-adsorbent material to the resin is less than 1% by weight, it is difficult to expect the gas adsorption performance, and when it is larger than 20% by weight, it is difficult to mold the composition to 1 to 20% by weight. The gas-adsorbing material is an adsorbent, and is at least one material selected from titanium oxide, calcium carbonate, activated carbon, elvan, zeolite, seven stone, and germanium in the form of a powder of 80 to 200 mesh, preferably 120 to 150 mesh. In this case, when the particles of the gas adsorbent are larger than 80 mesh, it is difficult to be mixed with the resin, and when smaller than 200 mesh, the manufacturing cost increases.
또한, 본 발명은 상기한 합성수지와 가스 흡착제의 조성물을 원료로 필름 혹은 용기의 식품포장재 형태로 성형한다.In addition, the present invention is formed from the composition of the synthetic resin and the gas adsorbent in the form of a food packaging material of a film or a container as a raw material.
본 발명에서 사용하는 상기한 가스 흡착제는 다공성과 전기화학적 작용으로 가스를 흡착하며, 주로 흡착하고자 하는 가스의 종류에 따라서 단독 또는 여러 성분들을 혼합하여 사용할 수 있다. 이러한 가스 흡착제로 사용되는 활성탄은 주성분이 탄소로서 다공성이고, 흡착력이 매우 강한 물질이다. 온도가 상승할수록 흡착력이 감소되고, 흡착시키고자 하는 물질의 농도가 높을수록 흡착력이 증가된다. 맥반석, 제올라이트, 칠보석 등은 나트륨, 칼륨, 칼슘과 같은 알칼리 또는 알칼리 토류 원소들의 결정형 알루미노 규산염을 포함하는 다공성 무기물이다. 이와 같이 가스 흡착제의 다공 특성에 따라 특정성분이나 물 등을 선택 흡착한다. 이러한 무기물의 가스 흡착제는 또한 접촉 항균성이 매우 우수한 것으로 알려져 있으며 일부는 비접촉에 의해서도 항균성을 보인다. 탄산칼슘, 산화티타늄, 게르마늄 등은 이온화되기 쉬운 무기물로서 이온 흡착력을 높이기 위한 목적으로 첨가하여 사용한다. Wherein a gas adsorbent to be used in the present invention is a gas adsorption in the porous and electrochemical action, according to the type of gas to be adsorbed mainly may be used alone or by mixing the various components. Activated carbon used as such a gas adsorbent is a material whose main component is carbon as porous and very strong adsorption power. The adsorption force decreases as the temperature increases, and the adsorption force increases as the concentration of the substance to be adsorbed increases. Elvan, zeolite, chile stone and the like are porous inorganic materials including crystalline aluminosilicates of alkali or alkaline earth elements such as sodium, potassium, calcium and the like. In this way, specific components, water, and the like are selectively adsorbed according to the porous characteristics of the gas adsorbent. These inorganic gas adsorbents are also known to have very good contact antimicrobial properties, some of which also exhibit antimicrobial properties. Calcium carbonate, titanium oxide, germanium, etc. are inorganic substances which are easily ionized, and are added and used for the purpose of increasing the ion adsorption power.
본 발명에서 사용되는 가스 흡착제는 다공성 혹은 이온화에 의한 흡착성능을 갖고 과채류의 호흡 및 증산작용 등에 의해 발생되는 에틸렌 가스와 산소를 흡착 제거함으로써 보다 장기간 과채류의 신선도를 유지할 수 있을 뿐만 아니라, 생선 및 육류로부터 방출되는 아민 등과 같은 냄새 유발 성분을 흡착하며, 이로써 식품의 판매 유통 기간을 연장하고 제품의 구매 동기를 높여 결과적으로 가격 경쟁력을 높게 할 수 있는 효과를 얻을 수 있다.The gas adsorbent used in the present invention has the adsorption performance by porosity or ionization, and can adsorb and remove ethylene gas and oxygen generated by the respiration and transpiration of fruit and vegetables to maintain freshness of the fruits and vegetables for a longer time, as well as fish and meat. Adsorption of odor-causing components such as amines released from the product, thereby extending the sales period of food and increasing the purchase motivation of the product can result in an effect that can increase the price competitiveness.
본 발명에 사용된 재료들의 흡착성능 및 재료가 발생하는 원적외선과의 시너지 효과를 극대화 할 수 있도록 최적의 혼합비를 모색하여 합성수지와 흡착성 물질을 혼합한 수지를 제조하는 것이 바람직하다.In order to maximize the adsorption performance of the materials used in the present invention and synergies with the far-infrared rays generated by the material, it is desirable to prepare a resin in which a synthetic resin and an adsorbent material are mixed by finding an optimal mixing ratio.

위 표 1로 부터, 본 발명의 가스 흡착성 수지조성물의 실시예 1-3들은 첨가되는 가스 흡착 재료의 종류 및 혼합 비율 혼합 조성에 따라서 흡착재료가 첨가되지 않은 비교예 1-3들에 비하여 수배에서 수십 배의 에틸렌과 암모니아 가스를 흡착하고 있음을 알 수 있다. 이것은 결과적으로 과채류에서 발생하는 숙성 호르몬인 에틸렌을 흡착하여 과채류의 유통 기한을 연장시킬 수 있음과 함께, 악취 유발 성분인 암모니아를 효과적으로 흡착하는 것은 어류나 육류로부터 발생하는 비린내 등을 효과적으로 억제할 수 있음을 의미한다. 따라서, 수지와 흡착제를 적당한 혼합비율로 조성한 본 발명의 흡착 수지조성물은 식품의 포장재료로 사용함으로써 과채류와 육류 및 어류의 신선도가 유지되고 제품의 신뢰성을 향상시켜 부가가치를 높여 줄 수 있음을 확인할 수 있다. From Table 1 above, Examples 1-3 of the gas-adsorbent resin composition of the present invention are several times higher than those of Comparative Examples 1-3, in which the adsorbent material is not added, depending on the type and mixing ratio of the gas adsorbent material added. It can be seen that it adsorbs dozens of times of ethylene and ammonia gas. As a result, the shelf life of fruit and vegetables can be extended by adsorbing ethylene, a ripening hormone that occurs in fruit and vegetables, and the effective adsorption of ammonia, an odor-causing component, can effectively suppress fishy smell from fish and meat. Means. Therefore, it can be confirmed that the adsorbent resin composition of the present invention, which has a resin and an adsorbent in an appropriate mixing ratio, can be used as a packaging material for food to maintain the freshness of fruits, vegetables, meats and fishes, and improve the reliability of the product to increase the added value. have.
또한, 위 표 1의 실시예 3에서 활성탄과 맥반석을 중량비로 50:50으로 조성된 흡착제를 20중량% 포함하는 수지조성물로 제조된 펠릿으로 두께 3mm, 직경 10cm로 압착 성형된 포장 용기와, 두께 50㎛로 사출성형된 포장필름으로 각각 사과 10개를 포장하고, 비교예3으로 제조한 포장용기와 포장필름으로 각각 사과 10개를 포장한 후 20℃, 상대습도 50%의 항온 항습기에 넣고 일주일 동안 경과한 다음 사과의 중량감소, FHM 과일경도계를 이용하여 측정한 경도 및 당도를 측정한 평균값을 아래 표 2에 표시하였다.In addition, in Example 3 of Table 1, the pellets made of a resin composition containing 20% by weight of an adsorbent composed of 50:50 of activated carbon and ganban stone in a weight ratio of 3 mm in thickness and 10 cm in diameter, the packaging container was press-molded, and the thickness, 10 apples are packed with 50 탆 injection-molded packaging film, 10 apples are packed with the packaging container and packaging film prepared in Comparative Example 3, and then placed in a constant temperature and humidity chamber at 20 ° C and 50% relative humidity. After passing through the weight loss of apples, the average value of hardness and sugar measured using the FHM fruit hardness meter is shown in Table 2 below.
표 2로 부터 본 발명의 흡착제를 포함하는 수지조성물로 부터 제조된 용기 및 필름에 의한 포장시험 결과, 수지만으로 제조된 비교예의 경우 보다 사과의 중량감소율이 낮아지고, 과피의 탄력이 높게 유지되는 것으로 나타났으며, 사과가 분비한 에틸렌 및 활성 산소의 제거에 의하여 과숙이 억제되었으나 사과의 당도는 떨어지는 것으로 나타났다.As a result of the packaging test with the container and the film prepared from the resin composition containing the adsorbent of the present invention from Table 2, the weight loss rate of the apple is lowered and the elasticity of the skin is maintained higher than that of the comparative example made of the resin alone. The fruit was suppressed by the removal of apple secreted ethylene and active oxygen, but the sugar content of the apple was lowered.
본 발명에 따른 흡착제를 포함하는 수지조성물은 과채류의 신선도를 유지하고 어류나 육류에서 발생되는 냄새 유발 성분을 흡착함으로써, 식품의 판매 유통 기간을 연장하고 제품의 구매 동기를 높여 결과적으로 가격 경쟁력을 높게 할 수 있는 포장용기나 포장필름과 같은 포장재료로 사용할 수 있다. The resin composition including the adsorbent according to the present invention maintains the freshness of fruit and vegetables and adsorbs odor-causing components generated in fish or meat, thereby extending the sales period of food and increasing the purchase motivation of the product, resulting in high price competitiveness. It can be used as a packaging material such as packaging container or packaging film.
