本发明涉及一种抗菌保鲜组合物、抗菌保鲜袋、抗菌保鲜装置及冰箱。The invention relates to an antibacterial fresh-keeping composition, an antibacterial fresh-keeping bag, an antibacterial fresh-keeping device and a refrigerator.
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传播，甚至繁殖，导致不新鲜。为了保持冰箱内食物达到抗菌以及抑制氧化和生化反应的目的，目前通常在冰箱内放置抗菌剂。目前常用的抗菌剂有很多种，如具有二氧化氯的抗菌剂，常用的二氧化氯的抗菌剂为用沸石、硅酸盐等吸附稳定性二氧化氯溶液后得到的固体粉末。但是，该种抗菌剂在使用的过程中易失水，从而影响抗菌保鲜的效果。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 is helpful for storing food, when the food is stored in the refrigerator for a long time, the bacteria will spread and even breed, resulting in not fresh. In order to maintain the antibacterial properties of the food in the refrigerator and to inhibit oxidation and biochemical reactions, antibacterial agents are usually placed in the refrigerator. At present, there are many kinds of antibacterial agents commonly used, such as an antibacterial agent having chlorine dioxide. The commonly used antibacterial agent for chlorine dioxide is a solid powder obtained by adsorbing a stable chlorine dioxide solution with zeolite or silicate. However, the antibacterial agent is prone to water loss during use, thereby affecting the effect of antibacterial preservation.
有鉴于此，有必要对现有的抗菌保鲜组合物予以改进以解决上述问题，并且还有必要提供一种抗菌保鲜袋、抗菌保鲜装置及冰箱。In view of this, it is necessary to improve the existing antibacterial fresh-keeping composition to solve the above problems, and it is also necessary to provide an antibacterial fresh-keeping bag, an antibacterial fresh-keeping device, and a refrigerator.

所用的松香包括一种或者两种有机酸的天然松香，如枞酸类(例如：枞酸，新枞酸，左旋海松酸等)；和产于世界各地的加工松香，如松香胶，浮油松香，木松香；上面提到的松香经氢化作用，歧化作用，聚合作用等得到的变性松香；以及上面提到的各种松香经酯化作用得到的松香酯(如：松香甘油酯)。这些松香在常温下是热塑性固体，熔点为约80℃-130℃。这其中熔点不超过110℃，特别是熔点不超过100℃的那些能有益地降低制备本发明组合物时的松香溶解温度，并在可能的最大程度上减少后面将提到的挥发性化合物与松香混合时的气化和损耗。The rosin used includes natural rosin of one or two organic acids, such as citric acid (eg, citric acid, neodecanoic acid, levorotatory acid, etc.); and processed rosin produced in various parts of the world, such as rosin, slick Rosin, wood rosin; the above-mentioned rosin obtained by hydrogenation, disproportionation, polymerization, etc.; and the rosin ester obtained by esterification of various rosins mentioned above (for example, rosin glyceride). These rosins are thermoplastic solids at ordinary temperatures and have a melting point of from about 80 ° C to 130 ° C. Those in which the melting point does not exceed 110 ° C, especially the melting point does not exceed 100 ° C, can advantageously reduce the rosin dissolution temperature in the preparation of the composition of the invention and, to the greatest extent possible, reduce the volatile compounds and rosin which will be mentioned later. Gasification and loss during mixing.
所用的挥发性化合物可以是，例如：各种天然及合成化合物中的一种或多种，这些化合物能以蒸汽的形式，产生芳香作用，除臭作用，杀细菌作用，抗细菌作用，杀真菌作用，防真菌作用，杀虫作用，防虫作用，抗氧化，抑制酶活性以及生化反应，并在使用本发明组合物的环境下挥发。特别是，挥发性化合物优选在使用本发明组合物的环境温度，如温度在0℃或者0℃以下的冰箱隔间，此时，可以使隔间内的药效浓度维持在0.03ppm。The volatile compounds used may be, for example, one or more of various natural and synthetic compounds which are capable of producing aroma, deodorization, bactericidal action, antibacterial action, fungicidal action in the form of steam. Action, antifungal action, insecticidal action, insect control action, antioxidation, inhibition of enzyme activity and biochemical reaction, and volatilization in the environment in which the composition of the present invention is used. In particular, the volatile compound is preferably at an ambient temperature in which the composition of the present invention is used, such as a refrigerator compartment having a temperature of 0 ° C or less, in which case the concentration of the drug in the compartment can be maintained at 0.03 ppm.
天然及合成物质的挥发性化合物的实例有：蒎烯，苎烯，里哪醇，薄荷 醇，萜烯醇，丁子香酚，乙酰苯，薰衣草油，日本扁柏油，桉树油，薄荷油，玫瑰油，芥子油，日本罗汉柏油，4-异丙基环庚二烯酚酮，二氧化氯，硫氰酸化合物，异硫氰酸化合物，异硫氰酸烯丙酯等等。Examples of volatile compounds of natural and synthetic materials are: terpenes, terpenes, linalool, mint Alcohol, terpene alcohol, eugenol, acetophenone, lavender oil, Japanese tar, eucalyptus oil, peppermint oil, rose oil, mustard oil, Japanese arhat oil, 4-isopropylcycloheptadienone, dioxide Chlorine, thiocyanate compound, isothiocyanate compound, allyl isothiocyanate and the like.
所用的增塑剂作用是为了便于抗菌保鲜组合物的混合和捏和，从而使该抗菌保鲜组合物在制备过程中挥发性化合物挥发掉的量较少，并且减少和预防了由组合物中的挥发性化合物的挥发作用引起的分散不均。除此，增塑剂还可以改善所得组合物的加工性能和保持最终产品的形态。增塑剂可以是任意的，例如：可为脂肪酸，脂肪酸酯，磷酸酯，蜡基团中的一种等。The plasticizer used is for the purpose of facilitating the mixing and kneading of the antibacterial fresh-keeping composition, so that the amount of volatile compounds volatilized during the preparation of the antibacterial fresh-keeping composition is less, and is reduced and prevented by the composition. Dispersion unevenness caused by volatilization of volatile compounds. In addition, the plasticizer can also improve the processability of the resulting composition and maintain the morphology of the final product. The plasticizer may be any, for example, may be one of a fatty acid, a fatty acid ester, a phosphate, a wax group, and the like.
脂肪酸的实例包括硬脂酸和月桂酸。脂肪酸酯可以是，如：脱水山梨糖醇月桂酸酯，癸二酸二丁酯或类似物质。至于磷酸酯可以用，例如：2-乙基己基磷酸二苯酯等。蜡基团的实例包括白蜡等。Examples of fatty acids include stearic acid and lauric acid. The fatty acid ester may be, for example, sorbitan laurate, dibutyl sebacate or the like. As the phosphate ester, for example, 2-ethylhexylphosphoric acid diphenyl ester or the like can be used. Examples of the wax group include white wax and the like.
每100重量份的松香中，增塑剂的用量为0.1-100重量份，优选10-50重量份。在本发明的范围内尤为优选的组合物的比例为：每100重量份的松香即有10-50重量份的增塑剂。当然，也可以不加增塑剂。The plasticizer is used in an amount of from 0.1 to 100 parts by weight, preferably from 10 to 50 parts by weight per 100 parts by weight of the rosin. A ratio of the composition which is particularly preferred within the scope of the present invention is 10 to 50 parts by weight of plasticizer per 100 parts by weight of rosin. Of course, it is also possible to dispense with no plasticizer.
在不妨碍本发明的组合物的作用前提下，本发明的组合物还可以含有各种常用的添加剂，如着色剂，结合预防剂等。但值得注意的是：当松香和挥发性化合物在该组合物中的总含量太小时，因松香含量不足会引发多种问题，如不能很好的控制释放，不能达到良好的加工性能，不能很好的保持最终的形态等；挥发性化合物的含量太少导致挥发时间缩短等。松香在组合物中的总含量为20％-60％。松香与挥发性化合物在所述组合物内所占的重量份比为：松香：100；挥发性化合物:大于100且小于或等于300。The composition of the present invention may further contain various conventional additives such as a coloring agent, a combination preventing agent and the like without impairing the action of the composition of the present invention. However, it is worth noting that when the total content of rosin and volatile compounds in the composition is too small, the lack of rosin content may cause various problems, such as poor control release, failure to achieve good processing properties, and inability to It is good to maintain the final form, etc.; the content of volatile compounds is too small, resulting in shortened volatilization time. The total content of rosin in the composition is from 20% to 60%. The parts by weight of rosin and volatile compounds in the composition are: rosin: 100; volatile compounds: greater than 100 and less than or equal to 300.
在该组合物制备时，为了防止所加入的成分氧化分解，特别是松香，可在空气或者惰性气氛(如氮气和二氧化碳)中，将挥发性化合物加入已加热熔化的松香中并与之混合。当使用增塑剂时，可先将其与松香混合，也可将挥发性化合物加入到增塑剂和松香中。In the preparation of the composition, in order to prevent oxidative decomposition of the added components, particularly rosin, volatile compounds may be added to and mixed with the heated melted rosin in air or an inert atmosphere such as nitrogen and carbon dioxide. When a plasticizer is used, it can be mixed with rosin or a volatile compound can be added to the plasticizer and rosin.
所述的组合物所用的挥发性化合物在室温下可以是液态或固体。液态可单独加入或通过常用的、不与挥发性化合物发生反应的适宜载体携带的粉末形式加入，这样的载体可以是，如纸浆，纸，纤维素颗粒，沸石，氧化铝，硅胶和硅酸钙。在温室下为固体时，可以粉末形式加入。The volatile compounds used in the compositions may be liquid or solid at room temperature. The liquid phase may be added singly or in the form of a powder which is carried by a suitable carrier which does not react with volatile compounds. Such carriers may be, for example, pulp, paper, cellulose granules, zeolites, alumina, silica gel and calcium silicate. . When it is a solid under the greenhouse, it can be added in the form of a powder.
由于挥发性化合物基本上是完全挥发的，因此在工业上重要的是在可能的最大程度上降低本发明组合物制备过程中，特别是因混合时的高温引起的 气化和损耗的量。为此，优选将制备过程中松香的溶解温度降低到，例如不超过100℃，优选75-90℃。一般情况下，优选采用方式如：在短时间内有效的完全混合，使用封闭型混合器，混合后立即包覆在包装袋内后即得成品(命名为抗菌保鲜袋)。当使用增塑剂时，在封闭型空间里先将松香与增塑剂完全混合，这有助于将挥发性化合物加入到他们中。Since the volatile compounds are substantially completely volatile, it is industrially important to reduce, to the greatest extent possible, the preparation of the compositions of the invention, especially due to the high temperatures during mixing. The amount of gasification and loss. For this purpose, it is preferred to reduce the dissolution temperature of the rosin during the preparation to, for example, not more than 100 ° C, preferably 75 to 90 ° C. In general, it is preferred to adopt a method such as: thorough mixing which is effective in a short time, using a closed type mixer, and immediately after being mixed and wrapped in a packaging bag, the finished product (named as an antibacterial fresh-keeping bag) is obtained. When a plasticizer is used, the rosin is thoroughly mixed with the plasticizer in a closed space, which helps to add volatile compounds to them.
所述的组合物可根据不同的使用目的以不同的方式使用，如呈薄片，块，粉末，颗粒，片剂中的任意一种形式。由于该组合物为热塑性的，其可容易地制备成各种形状。The composition may be used in various ways depending on the purpose of use, such as in the form of any of a sheet, a cake, a powder, a granule, and a tablet. Since the composition is thermoplastic, it can be easily prepared into various shapes.
为了更好的说明本发明所述的组合物，下面给出通过采用不同重量份比所得到的四种不同成分的组合物(组合物一、组合物二、组合物三、组合物四)以及实验数据来详细说明本发明的组合物在使用中所达到的抗菌和保鲜功效。In order to better illustrate the compositions of the present invention, compositions of four different ingredients obtained by using different weight ratios (Composition 1, Composition 2, Composition 3, Composition 4) are given below. Experimental data to detail the antibacterial and fresh-keeping benefits achieved by the compositions of the present invention in use.
