Abstract
Description
본 발명은 과일, 야채 등의 과채류나 화훼류를 포장할 때 선도유지기능을 부여할 수 있는 골판지 및 이를 포함하는 포장박스에 관한 것이다. The present invention relates to a cardboard box and a packaging box including the same, which can impart a freshness maintenance function when packaging fruits and vegetables such as fruits and vegetables.
과채류는 그 자체에서 에틸렌가스를 생성하여 성숙하는 것으로 알려져 있으며 밀폐된 포장용기에 과채류가 보관될 때 포장내용물로부터 에틸렌가스가 발생하고 이의 농도가 높아짐에 따라 포장물의 성숙이 촉진되어 포장물의 선도가 급격히 저하되어 상품성이 떨어지는 현상이 발생한다. Fruit vegetables are known to mature by producing ethylene gas in themselves, and when the fruits and vegetables are stored in closed packaging, ethylene gas is generated from the contents of the package and the concentration of the vegetables is accelerated, leading to the rapid growth of the package. The lowering of the commercial property occurs.
종래에는 로 과일, 야채 등의 과채류가 저장고 내에서 발생시킨 에틸렌가스를 다공성과 항균성을 가지는 무기물로 흡착시켜 신선도를 유지시키고 유해가스의 산화를 방지하므로서 신선도를 유지시키는 목적을 달성하고 있으나, 과채류의 운송과정이나 판매를 위한 야적장에서 또는 각 가정에서 소량으로 보관되는 경우에는 저장고 같은 대형 설비를 이용할 수 없는 문제점이 있다. Conventionally, fruits and vegetables such as fruits and vegetables are adsorbed by ethylene gas generated in the cellar with inorganic and porous and antimicrobial minerals to maintain the freshness and prevent the oxidation of harmful gases, but the purpose of maintaining the freshness of fruits and vegetables Large quantities, such as storage, are not available if they are stored in small quantities at transport or sale yards or at home.
그 밖의 종래의 기술로서 제올라이트, 크리스토발라이트, 크릴로프틸로와 같은 흡착성물질의 분말을 폴리에틸렌, 폴리프로필렌, 폴리부타디엔, 폴리초산비닐 등의 열가소성 합성수지 필름에 첨가하여 필름화한 신선도유지용 필름이 개발되어 채소 등의 신선도유지 효과를 얻고 있으나 에틸렌가스 흡착성 물질이 필름 속에 내재되어 합성수지로 차단되어 있는 상태로 존재하므로 에틸렌가스 흡수 속도가 느려 에틸렌가스 제거기능이 미흡하고 필름으로 완전히 밀폐포장을 할 경우에는 공기가 차단되어 도리어 청과물이 쉽게 상하는 문제가 발생하는 문제점이 있다.As another conventional technology, a film for maintaining freshness has been developed by adding a powder of an adsorbent material such as zeolite, cristobalite and krylopillo to a thermoplastic synthetic resin film such as polyethylene, polypropylene, polybutadiene and polyvinyl acetate. The freshness of the vegetable is maintained, but the ethylene gas adsorbent material is inherent in the film and is blocked by synthetic resin, so the absorption rate of ethylene gas is slow and the ethylene gas removal function is insufficient. There is a problem that the problem is that the fruits and vegetables are easily damaged is blocked.
따라서, 본 발명의 한 목적은 과채류나 화훼류에서 발생되는 에틸렌 가스를 효율적으로 제거하며 과채류나 화훼류의 선도가 떨어지면서 부패되는 것을 예방할 수 있는 항균성을 갖는 골판지를 제공하는데에 있다. Accordingly, one object of the present invention is to provide a corrugated cardboard having an antimicrobial ability to efficiently remove ethylene gas generated from fruits and vegetables and to prevent decay as the freshness of fruits and flowers falls.

표 1의 결과로부터, 본 발명의 신선도유지용 포장박스 제조시 흡착제의 종류와 항균성물질의 종류 및 혼합 비율과 혼합조성에 따라서 흡착제와 항균제가 초산과 암모니아 가스를 수배에서 수십배를 흡착하고 있음을 알 수 있다. 이것은 결과적으로 신선도유지용 포장박스에 처리된 흡착제와 항균제의 기능이 과채류에서 발생되는 숙성 호르몬인 유해가스인 에틸렌, 초산, 암모니아의 흡착을 통한 제거로 과채류의 유통기한을 연장시킬수 있음을 의미한다. 따라서, 흡착제와 항균제를 적당한 혼합비율로 조성한 본 발명의 신선도유지용 포장박스는 과채류의 포장박스로 사용함으로써 과채류의 신선도가 보다 오래 유지되어 제품의 신뢰성을 항상시켜 부가가치를 높여 줄수 있음을 확인할 수 있다. From the results of Table 1, it can be seen that the adsorbent and the antimicrobial adsorb several times to several times the acetic acid and ammonia gas depending on the type of adsorbent, the type, the mixing ratio and the mixing composition of the adsorbent, and the mixing ratio and the composition of the packaging box for maintaining the freshness of the present invention. Can be. As a result, the function of the adsorbent and the antimicrobial agent treated in the freshness maintaining box can extend the shelf life of the fruit vegetable by the adsorption of the harmful gases ethylene, acetic acid and ammonia, which are maturation hormones generated from fruit vegetables. Therefore, the freshness-maintaining packaging box of the present invention having an adsorbent and an antimicrobial agent in an appropriate mixing ratio can be confirmed that the freshness of the fruits and vegetables can be maintained longer by using the packaging box of the fruits and vegetables, thereby increasing the reliability of the product and increasing the added value. .
또한 실시예 3의 골판지로 조립한 포장박스에 사과 13개를 포장하고, 비교예 1의 골판지로 제조한 포장박스에 사과 13개를 포장한 후, 상기 두 박스를 20℃, 상대습도 50%의 항온항습기에 넣고 일주일 동안 경과한 다음 사과의 중량감소, FHM 과일경도계를 이용한 경도 및 당도를 측정하여 그 평균값을 구하였다. 그 결과는 표 2에 제시된다. In addition, 13 apples were packaged in a packaging box assembled from cardboard of Example 3, and 13 apples were packaged in a packaging box made of cardboard of Comparative Example 1. After a week in the thermo-hygrostat, the weight loss of apples, hardness and sugar content using FHM fruit hardness tester were measured and the average value was obtained. The results are shown in Table 2.
표 2의 결과로부터 본 발명에 따르는 포장박스는 기존의 포장 박스에 비해 사과의 중량감소율이 낮아지고, 과피의 탄력(경도)이 높게 유지되는 것으로 나타났으며, 사과가 분비하는 에틸렌, 유기산 등의 제거를 통해 신선도가 오랫동안 유지되는 기능은 우수하나 과육의 숙성을 지연시켜 기존의 포장 박스 내에 들어있는 사과에 비해 당도가 떨어지는 현상이 나타남을 알 수 있다. From the results of Table 2, the packaging box according to the present invention showed that the apple's weight loss rate was lower than that of the conventional packaging box, and the elasticity (hardness) of the skin was maintained, and the apple secreted by ethylene, organic acid, etc. Its freshness is maintained for a long time through its removal, but it can be seen that the sugar content decreases compared to the apples contained in the existing packing box by delaying ripening of the pulp.
