Abstract

The invention relates to a preparing method for a biological color developing agent, in particular to a biological color developing agent used in commodity packaging for judging time and a preparing method thereof. According to the preparing method for the biological color developing agent, 4.5 parts of juice of leaves of mirabilis jalapa, 1.8 parts of juice of leaves of euphorbia pekinensis, 3.2 parts of juice of leaves of parthenocissus tricuspidata and 50 parts of water are mixed uniformly by weight, coat a paper scrap or plastic, and change into brown black in 318-340 days under treatment of high temperature, low temperature, high humidity, low humidity, illumination and light shielding. According to the biological color developing agent, the time can be judged by means of the color difference, and the color change is not influenced by changes of materials and external conditions.

Description

technical field [0001] The invention relates to a preparation method of a biological chromogenic agent, in particular to a biological chromogenic agent used for judging time on commodity packaging and a preparation method thereof. [0002] The invention also relates to a label. [0003] The invention also relates to a medicine bottle. [0004] The invention also relates to a storage box. Background technique [0005] The chromogenic reagent is a reagent that develops the color of the complex produced after the biochemical reaction to achieve the purpose of the experiment. Commonly known as the substrate solution. An agent that imparts color to a component on paper or thin-layer board. With the development of science and technology, various new high-sensitivity and high-selectivity chromogens are constantly being synthesized. Traditional chromogenic agents are not only complex in composition, but also easily affected by environmental conditions. There are few reports on ...
