Abstract

The present invention relates to a dual-indication smart label for meat quality identification, a manufacturing method of the dual-indication smart label, and an application of the dual-indication smart label. The manufacturing method of the double-indicating smart label includes preparing the spinning solution for the base layer, preparing the spinning solution for the sensing layer of the volatile biogenic amine, and preparing the volatile H 2 S sensing layer spinning solution and preparation of double-layer fiber membrane and other steps. The dual-indication smart label of the present invention can not only provide relevant information such as meat type, weight, and meat product manufacturer, but also has multiple functions such as extending the shelf life of fresh meat and monitoring the freshness of meat in real time. Therefore, the smart label of the present invention has Very broad application prospects.

Description

【Technical field】 [0001] The invention belongs to the technical field of food detection. More specifically, the present invention relates to a smart label with double indications for meat quality identification, a method for making the smart label, and an application of the smart label. 【Background technique】 [0002] In recent years, frequent food poisoning incidents have caused many people to suffer from food poisoning every year. Therefore, food safety in my country has become a topic of great concern to people. Meat has become an indispensable part of people's daily life because of its high protein content. The quality of meat usually depends on the environment in which meat is packaged and delivered to consumers. During this period, it may be affected by many factors, resulting in food being contaminated by microorganisms, which directly affects the shelf life of meat. Therefore, in many transportation and sales environments Not all meat can be judged by simply smelli...
