Abstract
The device for testing food quality is a device for measuring the state of decay of a piece of food based upon measured electrical potential. The device includes a needle probe having an outer cylindrical shell formed from a first metal, such as stainless steel, and a wire mounted coaxially within the outer cylindrical shell. The wire is formed from a second metal, such as copper. A measuring device for electrical potential, such as a voltmeter, is further provided and is in communication with the needle probe. The device forms a galvanic cell when the probe is inserted into the food, the cell potential decreasing as a function of time in a manner corresponding to the state of decay of the piece of the food.
