Description

생육 및 육가공 제품용 선도유지 향상 포장재{WRAPPING MATERIAL FOR PRESERVING FRESHNESS OF FRESH-MEAT AND PROCESSING MEAT PRODUCT}WRAPPING MATERIAL FOR PRESERVING FRESHNESS OF FRESH-MEAT AND PROCESSING MEAT PRODUCT}

본 발명은 생육 및 육가공 제품용 포장재에 관한 것으로, 보다 구체적으로는 포장되는 생육 및 육가공 제품의 장기 신선도 유지를 위하여 항균력과 원적외선이 방사되는 선도개질제를 첨가하여 제공되는 생육 및 육가공 제품용 선도유지 향상 포장재에 관한 것이다.The present invention relates to a packaging material for growth and processing products, and more specifically, to maintain freshness for growth and processing products provided by adding antibacterial activity and a leading modifier that radiates far infrared rays to maintain long-term freshness of the packaging and processing products. It relates to a packaging material.

식품포장에 사용되는 포장재는 피포장물의 변패를 방지하고 선도저하를 최소화하기 위하여 가스 및 수분 차단성이 좋아야 한다. 일반적으로 식품 등을 포장할때 사용되는 포장재는 가스 및 수분 차단성이 좋은 적층 필름형 포장재가 사용되고 있는데, 기존의 포장재들은 외부로부터의 수분과 공기 등만이 차단되는 효과만 있을뿐 그 이상의 효과를 기대하기는 어려웠다.Packaging materials used for food packaging should have good gas and water barrier properties to prevent deterioration of packaged materials and to minimize freshness degradation. In general, a packaging film used for packaging food is used a laminated film type packaging material having good gas and moisture barrier properties. Existing packaging materials only have the effect of blocking only moisture and air from the outside. It was hard to expect.

특히 육류 제품의 경우에는 다량의 수분을 함유하고 온도에 민감하므로 유통기한이 짧고 유통 과정 중 조금만 지연되더라도 선도를 잃게 되어 제품의 가치가 떨어지게 되는 문제점이 있다.In particular, meat products contain a large amount of water and are sensitive to temperature, so the shelf life is short and there is a problem that the value of the product is lowered due to loss of freshness even if only a slight delay during the distribution process.

앞으로 생육의 부분 포장 의무화 및 생육의 브랜드화가 추진될 예정이므로 이에 따른 포장재에 대한 관심이 증진되고 있고 그 중요성 또한 부각되고 있는 바, 생육 및 육가공 식품의 신선도를 보다 더 장기간 유지할 수 있는 포장재 연구가 요구되게 되었다.In the future, mandatory partial packaging of growth and branding of growth will be promoted, and as a result, interest in packaging materials is increasing and its importance is also highlighted. Therefore, research on packaging materials that can maintain freshness of growth and processed foods for a longer period of time is required. It became.

본 발명자는 최근 다각적으로 연구되고 있는 원적외선에 착안, 원적외선 방사에 의한 바이오 효과와 항균력 부여로 생육의 신선도 향상 및 유통에 따른 변질을 최소화할 수 있는 포장재를 개발하게 되었다.The present inventors have developed a packaging material which can minimize the deterioration due to the improvement of freshness and distribution of growth by giving bio-effects and antimicrobial powers to the far-infrared rays, which have been recently studied in a variety of ways.

적외선 중 파장이 긴 원적외선은 물체에 잘 흡수되는 성질이 있고 그 분자속에서 공진되어 열로 변화되기 때문에 열전달 효율이 크다. 빛은 일반적으로 파장이 짧으면 반사가 잘 되고, 파장이 길면 물체에 도달했을 때 잘 흡수되는 성질이 있으므로 침투력이 강해서 사람의 몸도 이 적외선을 쐬면 따뜻해진다. 이러한 열작용은 각종 질병의 원인이 되는 세균을 없애는 데 효과가 있으며 모세혈관을 확장시켜 혈액순환과 세포조직 생성에 도움을 주고 세포조직을 활성화하여 노화방지, 신진대사를 활성화하는 효과가 있는 것으로 알려져 있다.Far infrared rays, which have a long wavelength among infrared rays, are well absorbed by an object and have high heat transfer efficiency because they are resonated in the molecule and converted into heat. In general, light has a short wavelength and reflects well, and a long wavelength has a property of being absorbed well when it reaches an object. This heat action is effective in eliminating bacteria that cause various diseases, and it is known to be effective in circulating capillaries to help blood circulation and formation of tissues and activating cellular tissues to prevent aging and metabolism. .

본 발명자는 상기한 원적외선의 효능과 생물체의 상태를 그대로 유지하는데 효과가 있음을 이해하고 생육 및 육가공 제품 포장을 위한 선도유지 향상 포장재로서 원적외선이 방사되는 포장재 개발을 완성하였다.The present inventors understood that the above-mentioned far infrared rays are effective in maintaining the state of the organisms as they are, and completed the development of a packaging material in which far infrared rays are radiated as a leading maintenance-improving packaging material for growth and processing of meat products.

본 발명은 생육 포장용 포장재 제조에 있어 별도의 추가되는 공정 없이도 피포장물의 항균 및 신선도 유지 효과를 극대화할 수 있는 것이다.The present invention is to maximize the antimicrobial and freshness maintaining effect of the packaged product without a separate process in the production of packaging packaging for growth packaging.

본 발명의 목적은 포장되는 생육 및 육가공 제품의 신선도 향상 및 유통에 따른 변질의 최소화를 위한 원적외선이 방사되는 포장재를 제공하는 것이다.It is an object of the present invention to provide a packaging material in which far-infrared rays are radiated for improving freshness and minimizing deterioration due to distribution of the grown and processed meat products to be packaged.

본 발명의 다른 목적은 별도의 추가공정 없이 피포장 생육 및 육가공 제품의 신선도 유지 효과를 극대화할 수 있는 포장재를 제공하는 것이다.Another object of the present invention is to provide a packaging material that can maximize the freshness maintaining effect of the packaged growth and processed meat products without additional processing.
