The present invention comprises: a layer of an adhesive agent; a film layer which is formed by micro processing, wherein the ammonia in the upper part of the layer of an adhesive agent may contact the indicator; an indicator packed layer which is discolored by ammonia gas which is penetrated, and installed in the upper part of the film layer; a transparent film layer which recognizes the color changes of the indicator packed layer with the naked eye by being installed in the outer side of the indicator packed layer.

Description

암모니아 변색 스티커{Discolored sticker by ammonia}Ammonia discoloration sticker {Discolored sticker by ammonia}

본 발명은 식품의 부패 확인을 위한 스티커에 관한 것으로, 식품의 부패 시 발생하는 암모니아와 지시약의 화학 반응에 의한 색 변화를 통해 식품의 부패 여부를 확인하는 암모니아 변색 스티커에 관한 것이다.The present invention relates to a sticker for confirming the decay of food, and relates to ammonia discoloration sticker for confirming the decay of the food through a color change by the chemical reaction of the ammonia and the indicator generated during the decay of the food.

일반적으로 축산물이나 유제품 등의 식품은 물론 각종 식품들은 제조 후에 시간이 경과됨에 따라 유통이나 보관 방법 등에 의하여 차등적으로 변질이 일어나게 된다. 하지만 식품의 종류에 따라 일률적으로 유통기간이나 보존기간을 명시하고 있어서, 변질이 빠르게 진행된 식품이라고 하더라도 단순히 유통기간이나 보존기간을 확인하는 방법에 의하여 식품의 신선도를 파악할 수밖에 없었다. 즉, 소비자는 식품의 신선도 여부를 제조연월일과 유통보존기간의 경과 여부만으로 신선도를 파악할 수밖에 없다. In general, foods such as livestock products or dairy products, as well as various foods, will be altered differentially by distribution or storage methods over time after manufacture. However, since the distribution period and the preservation period are uniformly specified according to the type of food, even if the food is rapidly deteriorated, the freshness of the food was determined by simply checking the distribution period or the preservation period. In other words, consumers have no choice but to determine the freshness of foods based only on the date of manufacture and the shelf life of the food.

이와 같이, 식품의 보관 상태나 기타 요인 등을 감안하지 않고 일률적으로 유통보존기간을 명시함으로써, 유통 및 보관 상태가 양호하지 않은 제품은 유통보존기간 중이라 하더라도 변질이 발생하여 식용(음용)시 건강을 위협하게 되고, 역으로 식품의 보관 상태가 좋은 제품은 유통 보존기간이 경과하더라도 식용 가능할 정도로 신선도가 유지되고 있음에도 불구하고 폐기할 수밖에 없다.As such, by clarifying the distribution preservation period uniformly without taking into account the food storage condition or other factors, products with poor distribution and storage conditions may be deteriorated even during distribution preservation periods, resulting in health when eating (drinking). On the contrary, even if the shelf life of the food is good, the product has to be discarded despite being kept fresh enough to be edible.

특히, 육류가 부패되면 붉은 고기색이 녹색, 갈색, 회색 등으로 변하게 되고, 불쾌한 냄새와 맛을 내게 되며, 또한 고기 표면에 점질 물질이 발생되게 된다. 하지만 이와 같은 육류의 부패는 부패가 어느 정도 진행되어야만 알 수 있어 초기 단계에서 기구나 장비 없이 인간의 감각만으로 부패의 진행 여부를 판단하기는 매우 어렵다. 또한 후각적으로 판단하기 위해서 직접 안 좋은 냄새를 맡아야함으로 사용자의 불쾌감은 매우 높아지게 될 것이다.In particular, when the meat is decayed red meat color is changed to green, brown, gray, etc., give an unpleasant smell and taste, and also a viscous material is generated on the surface of the meat. However, the corruption of meat can be known only when the corruption is progressed to some extent, so it is very difficult to determine whether the corruption is progressing only by the human sense in the initial stage without any equipment or equipment. In addition, the user's discomfort will be very high because the smell must be smelled directly in order to judge the sense of smell.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출한 것으로서, 제품의 제조연월일과 유통 보존기간과 관계없이 유통되거나 보관된 제품의 신선도를 육안으로 파악이 가능하도록 하는 암모니아 변색 스티커를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and to provide an ammonia discoloration sticker that allows the naked eye to grasp the freshness of the product distributed or stored regardless of the date of manufacture and shelf life of the product. have.

상기한 목적을 달성하기 위하여, 점착제층과, 상기 점착제층 상부에 암모니아 가스가 지시약과 접촉 가능하도록 미세가공이 형성된 필름층과, 상기 필름충의 상부에 구비되며 통과된 암모니아 가스에 의하여 변색되는 지시약 충진층과, 상기 충진층의 외측에 형성되어 충진층의 색변화를 육안으로 판단할 수 있는 투명필름층으로 이루어지는 암모니아 변색 스티커를 제공한다.In order to achieve the above object, the pressure-sensitive adhesive layer, the film layer having a micro-processing is formed so that the ammonia gas is in contact with the indicator on the pressure-sensitive adhesive layer, and the indicator filling is discolored by the ammonia gas passed on the top of the film filling It provides an ammonia discoloration sticker consisting of a layer and a transparent film layer formed on the outside of the filling layer to determine the color change of the filling layer with the naked eye.

본 발명의 적절한 실시형태에 따르면, 상기 지시약은 페놀프탈레인, 티몰 블루, 피나크롬, 브롬티몰 블루 및 메틸 오렌지로 이루어진 군에서 선택된 1종인 것이 바람직하다.According to a preferred embodiment of the present invention, the indicator is preferably one selected from the group consisting of phenolphthalein, thymol blue, pinachrome, bromthymol blue and methyl orange.

식품에 표기된 유통기간에 구애받지 않고 식품의 정확한 품질 상태를 검출하여 사용자에게 보다 정확한 사용 가능여부를 판단할 수 있도록 할 수 있다.Regardless of the distribution period indicated on the food, it is possible to detect the exact quality of the food to determine whether the user can use more accurately.

도 1은 본 발명의 암모니아 변색 스티커의 측면도를 도시한 것이다.
도 2는 암모니아 변색 스티커의 변색 과정을 도시한 것이다.Figure 1 shows a side view of the ammonia discoloration sticker of the present invention.
2 illustrates a discoloration process of the ammonia discoloration sticker.

본 발명에 따른 식품의 부패 확인을 위한 암모니아 변색 스티커는 점착제층(1)과, 상기 점착제층 상부에 암모니아 가스가 지시약과 접촉 가능하도록 미세가공이 형성된 필름층(2)과, 상기 필름층의 상부에 구비되며 통과된 암모니아 가스에 의하여 변색되는 지시약 충진층(3)과, 상기 충진층의 외측에 형성되어 충진층의 색변화를 육안으로 판단할 수 있는 투명필름층(4)으로 구성된다.The ammonia discoloration sticker for confirming the corruption of food according to the present invention includes a pressure-sensitive adhesive layer (1), a film layer (2) formed on the pressure-sensitive adhesive layer to allow ammonia gas to contact the indicator, and an upper portion of the film layer. It is composed of an indicator filling layer (3) provided in and discolored by the passed ammonia gas, and a transparent film layer (4) formed on the outside of the filling layer to visually determine the color change of the filling layer.

본 발명의 도 1에 도시한 것과 같이, 암모니아 변색 스티커는 식품의 용기 일측면에 부착시킬 수 있도록 점착층(1)이 구비되며, 상기 점착제층 상부에 식품의 부패 시 발생되는 암모니아 가스가 지시약과 반응 가능하도록 미세가공이 형성된 필름층(2)과, 상기 필름층의 상부에 구비되며 상기 미세가공이 형성된 필름층을 통해 통과된 암모니아 가스가 특정 pH에서 화학반응을 하는 지시약 충진층(3)이 형성된다. 상기 충진층의 외측에 형성되어 충진층을 형성함과 아울러 충진층의 상변화를 육안으로 판단할 수 있는 투명필름층(4)이 암모니아 변색 스티커 외측에 형성되어 있다. 상기 지시약은 페놀프탈레인, 티몰 블루, 피나크롬, 브롬티몰 블루 및 메틸 오렌지로 이루어진 군에서 선택된 1종을 사용할 수 있다.As shown in Figure 1 of the present invention, the ammonia discoloration sticker is provided with a pressure-sensitive adhesive layer (1) to be attached to one side of the container of the food, the ammonia gas generated during the decay of food on the pressure-sensitive adhesive layer and the indicator The film layer 2 formed with micromachining to react and the indicator filling layer 3 provided with an ammonia gas passed through the film layer formed with micromachining to perform a chemical reaction at a specific pH are provided. Is formed. The transparent film layer 4 formed on the outer side of the filling layer to form a filling layer and visually determine the phase change of the filling layer is formed outside the ammonia discoloration sticker. The indicator may be used one selected from the group consisting of phenolphthalein, thymol blue, pinachrome, brothymol blue and methyl orange.

상기와 같이 구성된 본 발명의 암모니아 변색 스티커의 작용을 설명하면, 식품의 부패 시 암모니아 가스가 발생하게 되며, 이러한 암모니아 가스가 미세가공이 형성된 필름층(2)을 통하여 통과하므로 지시약으로 전달되게 된다. 암모니아는 알칼리성이므로 지시약과 반응하여 색깔이 변하게 된다.When explaining the action of the ammonia discoloration sticker of the present invention configured as described above, ammonia gas is generated when the food decay, this ammonia gas is passed through the film layer (2) formed with micro-processing is delivered to the indicator. Ammonia is alkaline and reacts with the indicator to change color.

예를 들어, 도 2에 도시한 것과 같이, 페놀프탈레인 용액은 pH가 7.0에서 암모니아에 의해 pH가 7.1 내지 8.0 또는 그 이상으로 변화하여 색깔이 붉은 색으로 변하게 된다. 상기 충진층(3)의 외측에 형성되어 충진층을 형성함과 아울러 충진층의 색변화를 육안으로 판단할 수 있는 투명필름층(4)이 암모니아 변색 스티커 외측에 형성되어 있어, 색깔이 변화되므로 육안으로 신선도 식별이 가능해진다.For example, as shown in Figure 2, the phenolphthalein solution is changed to a red color by changing the pH from 7.1 to 8.0 or more with ammonia at pH 7.0. Since the transparent film layer 4 formed on the outside of the filling layer 3 to form a filling layer and visually determine the color change of the filling layer is formed on the outside of the ammonia discoloration sticker, the color is changed. The freshness can be identified with the naked eye.
