摘要

抽象。智能包装是新的包装技术之一,可以告知产品或环境的变化,如温度、pH和微生物生长。在这项研究中,将从菠菜提取物的天然来源开发智能packaging影片标签。从一项研究中发现,pH = 2的红色菠菜提取物具有最高的吸收值、最多的酸性和最纯的颜色,这证明了UV-Vis的峰值。FTIR的测试结果显示,在包装标签的样本中仍能检测到红色菠菜提取物。电影标签浓度为6%、8%和10%有红色菠菜提取物,强大吸引力和厚度测试制服的平均价值为拉长拉测试0.015毫米厚度,强大的价值5.67 kgf / cm²,测试0,19%拉长。红色菠菜提取物浓度为6%、8%和10%,其颜色呈实变化,易于观察。不仅是物理测试、全为性的UV-Vis、FTIR和她的电影标签颜色的变化,其浓度为6%、8%、10%,而且可以应用于肉类包装。抽象。智能packaging是一种新技术,它可以揭示出在其产品或环境中发生的火灾、温度、pH和微观增长。在这个研究中,基于pH值传感器的智能包装影片将在《红色spinach extract》的形式中开发出来。从研究结果来看,它发现红色spinach与pH值的extract = 2具有highest吸收值、最轻微的acids值,以及对其他pHs最有力的纯色对应于其他pHs,这是uv相对于highest峰的证据。FTIR的结果表明,红spinach extract仍在叛军的样本中发现。电影和红spinach labels extract concentrations of 6%、8%和10%有制服thickness,肌腱力量与elongation test results with an thickness测试》平均价值为0.015毫米,肌腱力量测试with a 5。67 kgf / cm²的价值,和0。19%的elongation测试。带有红色spinach extract concention的叛军电影6%、8%和10%都是坚定的颜色和产品,几乎可以观察颜色。不仅在物理测试中,机械characteristics UV-Vis, FTIR和changes在颜色中,具有6% 8%到10%一致性的实验室进行了良好的检测,并可以应用于肉类包装。
