AI Technical Summary

Technical Problem

Existing food testing labels have a small detection range, poor accuracy, and unclear colorimetric response in low-light environments. The color brightness of mixed colorimetric indicator materials is weakened, leading to inaccurate detection.

Method used

By selecting chemical indicators that respond to color changes in response to chemical atmosphere variables, colorimetric response data is acquired and stored in a smart device. Based on the data, an array unit and a programming diagram for the sensor indicator label are generated. The smart device is then used to arrange the chemical indicator color blocks into an array unit and print them onto a substrate to form a hybrid visual sensing smart indicator label.

Benefits of technology

This improves the universality and detection sensitivity of the tags, ensures that the actual response of the tags matches the theoretical prediction, and enhances observability and recognition accuracy in low-light environments.

Abstract

本发明涉及食品检测技术领域,公开了可编程混合视觉传感智能指示标签的制备方法及应用方法,本发明基于包装产品中的化学气氛变量,选择化学指示剂以及指示标签基材;获取化学指示剂比色响应数据并存储至智能设备,将至少两种化学指示剂各自对应的指示剂色块调整排列,生成阵列单元承印至指示标签基材,得到混合视觉传感智能指示标签,固定于待检测包装产品中的顶空部位,在不小于预设观测距离的位置,观测标签。由于色块间不接触,色块材料间的相互作用被消除,观测颜色为色块颜色的加权平均色,颜色准确度提高,有利于肉眼精确观测,在减少建立比色响应数据库工作量、提高标签普适性的情况下,确保标签实际响应与理论预测匹配。
