抗菌保鲜组件及其制备方法，以及冰箱Antibacterial fresh-keeping component and preparation method thereof, and refrigerator 技术领域Technical field

背景技术Background technique
冰箱为保持恒定低温的一种制冷设备，也是一种使食物或其他物品保持恒定低温状态的产品。目前，随着人们生活水平的不断上升，通常会定期购置比较多的食物存放在冰箱内，以便随时食用。虽然冰箱的低温会抑制部分常温和喜高温细菌的繁殖，对存储食物有一定的帮助，但是，当食物长期存放在冰箱内后仍会发生细菌尤其是喜冷细菌的繁殖和传播，导致不新鲜。为了抑制冰箱内食物中细菌的生长和繁殖，以及抑制氧化等生化反应的目的，目前通常在冰箱内放置抗菌剂，如具有二氧化氯的抗菌剂，但是，在使用此种抗菌剂的时候，一般需要在冰箱内开辟一个空间用以放置该抗菌剂，所以较占空间。而除在冰箱内放置抗菌剂外，目前还有直接将银离子抗菌剂注塑或者挤出到冰箱的塑料组件中以制得具有银离子的抗菌组件，从而通过该抗菌组件达到抗菌的作用。但是，此种抗菌组件在使用的过程中存在如下缺陷：1、银系抗菌剂属于接触性杀菌，细菌必须与添加抗菌剂的部件直接接触才能杀灭，2、银系抗菌剂寿命短，一般存在于部件的表面，经历水洗后表面的抗菌剂数量将减少，杀菌效果降低，3、银系抗菌剂成本高。A refrigerator is a type of refrigeration device that maintains a constant low temperature and is a product that keeps food or other items at a constant low temperature. At present, as people's living standards continue to rise, they usually purchase more foods in the refrigerator regularly for consumption at any time. Although the low temperature of the refrigerator will inhibit some of the normal temperature and the proliferation of high-temperature bacteria, it will help the storage of food. However, when the food is stored in the refrigerator for a long time, the reproduction and spread of bacteria, especially the cold bacteria, will occur. . In order to suppress the growth and reproduction of bacteria in food in the refrigerator, and to inhibit the biochemical reaction such as oxidation, an antibacterial agent such as an antibacterial agent having chlorine dioxide is usually placed in a refrigerator, but when such an antibacterial agent is used, It is generally necessary to open a space in the refrigerator for placing the antibacterial agent, so it takes up more space. In addition to placing an antibacterial agent in the refrigerator, there is currently a direct injection or extrusion of a silver ion antibacterial agent into a plastic component of a refrigerator to obtain an antibacterial component having silver ions, thereby achieving an antibacterial effect by the antibacterial component. However, such an antibacterial component has the following defects in the process of use: 1. The silver-based antibacterial agent belongs to contact sterilization, and the bacteria must be directly contacted with the component to which the antibacterial agent is added to kill. 2. The silver-based antibacterial agent has a short life span. Existing on the surface of the component, the amount of the antibacterial agent on the surface after the water washing is reduced, the sterilization effect is lowered, and the cost of the silver-based antibacterial agent is high.
有鉴于此，有必要对现有的抗菌保鲜组件及其制备方法，以及冰箱予以改进，以解决上述问题。In view of this, it is necessary to improve the existing antibacterial fresh-keeping components, the preparation method thereof, and the refrigerator to solve the above problems.

实验一experiment one

During this period, the four antibacterial fresh-keeping components were weighed at intervals, and the reduced weight was regarded as the amount of volatile compounds volatilized, and the volatilization rate (%) was calculated in terms of time (volatility = reduced weight of the antibacterial fresh-keeping component test) / Original weight of the antibacterial fresh-keeping component), the relevant data is shown in Figure 1.
从图1中可看出，上述四个抗菌保鲜组件在挥发性化合物的释放性能上是优越的，可持续挥发，并且可看出，随着实验时间，挥发率趋向于恒定，同时还测得各隔间内的药效浓度稳定地保持在0.01-0.4ppm。As can be seen from Fig. 1, the above four antibacterial fresh-keeping components are superior in the release property of volatile compounds, and can be continuously volatilized, and it can be seen that the volatilization rate tends to be constant with the experiment time, and it is also measured.
