Description
본 발명은 식품포장지 코팅용 새로운 은항균전분 제조에 관한 것으로 현재 아이스크림, 식품, 통닭 등의 식품 포장지로 널리 사용되고 있는 식품포장지에 전분을 이용하여 한쪽면에 코팅하여 사용하고 있다.The present invention relates to the production of a new silver antibacterial starch for food packaging paper coating is currently used as a food wrapping paper such as ice cream, food, chicken, etc. by using starch coated on one side.
전분은 위생적이고 인체에 무해할 뿐 아니라 가격이 저렴하므로 식품 포장지 단면에 롤을 이용하여 코팅하면 광택이 나고 종이에 붙은 부유물질이 식품에 오염되지 않게 하기 위하여 널리 상요하고 있다. 화공약품인 P.V.A나 필림을 코팅하여 사용할 경우 환경공해를 야기시키고 P.V.A 역시 인체에 유해성이 있어 사용상 문제가 되고 있다.Starch is not only hygienic and harmless to the human body, but also low in price, so it is widely used to prevent gloss and suspended matter attached to paper from being coated with rolls on the cross section of food packaging. Coating with chemicals such as P.V.A or film causes environmental pollution, and P.V.A is also harmful to the human body, causing problems in use.
상기 전분은 이러한 문제점을 해결할 수 있으나 식품포장지로 사용할 경우 많은 세균들이 서식하고 곰팡이 등의 사각지대가 되고 있다.The starch can solve this problem, but when used as a food packaging paper, many bacteria inhabit and become a dead zone such as mold.
본 발명은 이러한 문제점을 해결하기 위하여 인체에 무취, 무독이고 항균성이 우수한 은항균제를 상기 전분을 제조할 때 물에 100ppm정도 은용액을 희석하여 전분을 끓여 항균효과를 얻을 수 있도록 한 것이 특징이다.The present invention is characterized in that the antibacterial agent odorless, non-toxic and excellent antimicrobial to the human body to prepare the starch by diluting the silver solution about 100ppm in water to obtain the antimicrobial effect.
현재까지 은콜로이드용액은 전기분해로 나노와 같이 작은 입자를 물에 용출시켜 은콜로이드용액을 제조하는 기술과 은염을 이용하여 은콜로이드용액을 제조하는 기술 등이 보현화되어 있으나 이들의 은염이나 은콜로이등 용액은 햇볕이나 하로겐 화합물 등과 결합하면 흑변되거나 황변 되는 것이 은 염의 고유의 성질이다.Until now, silver colloidal solution has been developed by electrolysis to produce silver colloidal solution by dissolving small particles like nanoparticles in water and silver colloidal solution using silver salt. It is the inherent property of silver salts that the back solution turns black or yellow when combined with sunlight or halogen compounds.
본 발명은 이러한 은염의 성질을 완전히 배제한 새로은 은염을 제조하기 위하여 은괴를 소립하여 용해조에 넣고 질산을 첨가시켜 은을 용해한 후 탄산칼슘용액(PH9.5)을 첨가시켜 중성으로 만들면서 빙초산을 첨가시키면서 PH5정도가 되게 하면 작은 입자의 은염이 제조된다.In the present invention, in order to prepare a new silver salt that completely excludes the properties of the silver salt, the silver ingot is put in a dissolution tank, and nitric acid is added to dissolve silver, and then calcium carbonate solution (PH9.5) is added to make neutral, while adding glacial acetic acid. When the pH is about 5, silver particles of small particles are produced.
상기 은염 100g을 물 1,000g에 합성하여 황산제1철을 첨가시켜 교반하여 가성소오다로 PH를 조정하여 1시간 정도 방치하면 침전물이 생긴다.100 g of the silver salt was synthesized in 1,000 g of water, ferrous sulfate was added thereto, stirred, and the pH was adjusted with caustic soda and left for about 1 hour to form a precipitate.
상기 침전물은 투명액체의 콜로이드가 만들어진다. 이때 은콜로이드의 은고형분을 측정하면 약10,000PPM의 은이 함유되어 있는 것이 확인되고 있다.The precipitate is made of a colloid of transparent liquid. At this time, when the silver solid content of silver colloid is measured, it is confirmed that silver of about 10,000PPM is contained.
상기 은염을 전분을 제조하는 물에 약 100PPM정도 은이 함유되면 전분을 넣고 전분풀을 끓여 식품포장지 코팅제로 사용할 경우 항균성이 99.9％ 항균되는 것이다. 이때 새로운 은염은 황변이 되지 않고 은항균전분이 코팅된 포장지에는 황변이나 흑변이 일어나지 않고 깨끗한 식품포장지가 제조되고 은이 함유된 전분풀 역시 황변이나 흑변이 되지 않는 것이 확인되고 있다.When the silver salt contains about 100PPM silver in the water to prepare the starch, when the starch is added and the starch pool is used as a food packaging coating agent, the antimicrobial activity is 99.9% antibacterial. At this time, the new silver salt does not become yellowed, silver antibacterial starch coated paper is not produced yellowing or black stools, clean food packaging is produced, it is confirmed that the starch pool containing silver does not become yellow or black stools.
상기와 같이 본 발명의 기술핵심은 새로운 은염제조시 은을 유기산에 용해하여 탄산칼슘으로 중화하여 다시 빙초산으로 PH5로 한 후 상기 은염을 물에 용해한 후 은이 철분 등과 결합할 경우 검은 앙금 등을 유발시킨다. 이때 황산 제1철의 량 은 상기 은용액의 0.1％를 초과하지 않도록 한 것이 특징이다. 이것은 은용액이 일반 수돗물이나 지하수에 함유된 철분 등과 결합할 때 흑변되는 현상을 막기 위하여 1차로 철염을 이용한 것이 특징이다.As described above, the technical core of the present invention dissolves silver in an organic acid and neutralizes it with calcium carbonate when preparing a new silver salt, and then converts it to PH5 with glacial acetic acid, and then, when silver is dissolved in water and silver is combined with iron, it causes black sediment. . At this time, the amount of ferrous sulfate is characterized in that it does not exceed 0.1% of the silver solution. It is characterized by the primary use of iron salts to prevent blackening when silver solutions combine with iron in groundwater or groundwater.
상기와 같이 용해된 은용액을 여과시에 여과시키면 투명액체의 은콜로이드용액이 제조된다.When the silver solution dissolved as mentioned above is filtered at the time of filtration, the silver colloidal solution of a transparent liquid is manufactured.
상기 은용액의 은함유량을 한국화학시험연구원에 은함유량 측정결과 은이 10,000PPM 함유된 것이 확인되고 있다.The silver content of the silver solution was measured by the Korea Chemical Testing and Research Institute that the silver content was confirmed to contain 10,000 PPM silver.
상기 은용액을 전분을 이용하여 풀을 끓일 때 사용되는 물에 100PPM정도 희석하여 전분풀을 제조했을 때 대장균, 포도상구균이 99.9％ 항균되는 것이 확인되고 있다.It is confirmed that E. coli, Staphylococcus aureus is 99.9% antibacterial when the silver solution is diluted to about 100PPM in water used to boil the pool using starch.
본 발명은 기존 전분풀을 새로운 은용액을 제조하여 색상이 변하지 않는 은항균 전분을 제조한 것이 특징이다.The present invention is characterized by the production of silver antibacterial starch that does not change color by producing a new silver solution of the existing starch pool.

In order to prepare a new silver antibacterial agent, silver is dissolved by adding nitric acid while maintaining silver at 80 degrees in a dissolution tank to dissolve silver and then dissolving silver carbonate in water. After the glacial acetic acid is added to the silver solution to make PH5, small light brown particles are formed.
상기 연갈색의 은염 100g을 물 1,000g에 용해한 후 황산제1철(40％)을 상기 은용액에 0.1％ 첨가시켜 반응시키면서 PH를 조절하기 위하여 가성소오다용액을 첨가하고 교반시켜 1시간정도 햇볕에 방치하면 많은 침전물이 생긴다.After dissolving 100 g of the light brown silver salt in 1,000 g of water, ferrous sulfate (40%) was added to the silver solution by adding 0.1% of the caustic soda solution to adjust the pH, followed by stirring for 1 hour in the sun. If left unattended, a lot of sediment is formed.
상기 침전물을 여과하면 투명액체의 은항균콜로이드용액이 제조된다.Filtration of the precipitate produces a silver antibacterial colloidal solution of a clear liquid.
