Abstract

The invention relates to a double-indication intelligent label capable of identifying meat quality, a manufacturing method of the double-indication intelligent label and application of the double-indication intelligent label. The manufacturing method of the double-indication intelligent label comprises the steps of preparing a base layer spinning solution, preparing a volatile biogenic amine sensing layer spinning solution, preparing a volatile H2S sensing layer spinning solution, preparing a double-layer fiber membrane and the like. The double-indication intelligent label can provide relevantinformation such as meat types, weights and meat manufacturers, and has multiple functions of prolonging the shelf life of fresh meat, monitoring the freshness of the meat in real time and the like,so that the intelligent label has a very wide application prospect.

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...
