Food corrosion determiner

Abstract

The present invention relates to a food corrosion confirmation device that can immediately know the freshness of stored products with the naked eye through a display regardless of the date of manufacture and the shelf life of the product. In order to achieve the above object of the present invention, it includes: a flat plate that can place food; a contact detector that is formed on the upper part of the above plate, directly contacts with the food, and detects the pH value of the food that changes according to the quality state; The pH detection section that checks the degree of food corrosion by the potential difference between the pH value detected by the above-mentioned contact detector and the pH value that has been set as a standard; the one that controls the ON / OFF of the external indicator light according to the corrosion degree detected by the above-mentioned pH detection section control department. It enables the user to judge more accurately whether the food has been corroded and whether it is edible.

Description

technical field [0001] The present invention relates to a food corrosion confirming device, in particular to a food corrosion confirming device which changes the ion concentration difference into an electromotive force difference by measuring the pH of food, and uses the difference to confirm the food corrosion status. Background technique [0002] Generally, various foods such as livestock products and dairy products are corroded to varying degrees over time depending on distribution or storage methods after manufacture. Since the distribution period or storage period is marked according to the type of food, even if it is a food that corrodes quickly, the freshness of the food can only be confirmed according to the distribution period or shelf life. [0003] That is, consumers can only judge the freshness of food according to the date of manufacture and shelf life. [0004] In this way, there are the following disadvantages in the method of always indicating the shelf life...

Problems solved by technology

Consequently, there will be disadvantages that the system volume becomes larger

[0012] Moreover, when a pH-sensitive polymer substance is produced, changes in the molar ratio of pH-sensitive methane chloride and N,N-dimethylacrylamide affect the transparency, thereby adjusting the material reaction ratio and based on the above ratio When the pH range is higher, the error range will become larger

[0013] That is, the method of using pH paper or indicators to detect color changes according to the pH level has the following disadvantages: there are certain limitations in the accuracy of the indicator itself, and it is difficult to detect colored or dark-colored test materials

Consequently, it is difficult to accurately confirm the degree of corrosion of food

[0014] It can be seen that the above-mentioned existing food corrosion confirmation device obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the problems of food corrosion confirmation devices, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and general products do not have a suitable structure to solve the above problems. Obviously, it is a problem that relevant industry players are eager to solve.
