Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

Referring to fig. 1 and 2, the present embodiment relates to a convenient smart label for inspecting whether raw meat is deteriorated, comprising a transparent plate 1, microneedles 2 and a color developing reagent, wherein the microneedles 2 are bio-soluble materials, and the microneedles 2 are cavity structures; the developing reagent is filled in the microneedle 2; after the microneedle 2 penetrates into the raw meat, the microneedle 2 is gradually dissolved to release the color developing reagent in the microneedle 2, so that the reagent is contacted with the raw meat; when raw meat is deteriorated, microorganisms generated from the raw meat and the color developing reagent are subjected to a color developing reaction, and a change in color can be observed through the transparent plate 1. The micro-needle 2 is made of soluble material; most preferably, a wide variety of biocompatible Polyhydroxyalkanoate (PHA) materials are selected. When the transparent plate 1 is attached to raw meat, the tips of the microneedles 2 penetrate the surface of the raw meat and enter the raw meat.

When the label is attached to the raw meat, the needle point of the microneedle 2 penetrates through the surface of the raw meat and enters the raw meat, so that the microneedle 2 is wrapped, and then the soluble microneedle 2 is gradually dissolved to release the color developing reagent inside the microneedle 2, so that the color developing reagent is contacted with the raw meat. If the meat quality is deteriorated, microorganisms generated by raw meat and a color reagent are subjected to color development reaction, and the color can be observed to be changed through the transparent plate 1 by naked eyes; if the meat quality is not deteriorated, the color is not changed through naked eyes, and the meat quality-changing machine has the advantages of simple structure, simplicity in use, convenience and quickness.

The chromogenic reagent is a Polyhydroxyalkanoate (PHA) material. The microorganism produced by the raw meat is staphylococcus aureus. The invention adopts the detection of staphylococcus aureus in raw meat as a parameter for determining whether the raw meat is deteriorated. Among the microorganisms causing food poisoning by food-borne microorganisms, staphylococcus is one of the main pathogenic bacteria, and the growth rate of staphylococcus in meat products is very rapid. And 25% of food poisoning events caused by staphylococcus aureus in China, the chromogenic reagent adopted by the invention is a nontoxic 5-bromo-4-chloro-3-indolyl phosphate reagent. The principle is that the color reagent can be generated by catalyzing and hydrolyzing by phospholipase generated by staphylococcus aureus, alcohol is generated, enol is oxidized into blue dimer particles, bacterial colonies are made to be blue, and therefore color change can be simply and directly observed to obtain the condition of whether the color reagent is deteriorated or not.
