A novel measurement method for egg quality identification

In food industries, the usage of eggs in different products plays a very important role.The quality of eggs consists of various aspects of quality, each of which can be related to the quality of interior eggs or the quality of external eggs. Chitin's crisp egg-shell does not bear the collision and extrusion, and is very easy to damage. The external microorganism will reach the shell easily through the crack if the egg-shell has been split, so the decaying of the egg is accelerated or the consistency is decreased. The parameters such as color, thickness, shell strength, eggshell crack, bloodspots, porosity, air cell depth, shell integrity and freshness can also be used to detect the contaminated egg. But the weight loss and change in temperature gives us the variation in quality of the egg gradually and accurately. A simple method is proposed in which the key parameters like weight and temperature is measured using suitable sensor. The analog output from the sensor is fed to the Arduino board as an input signal for further processing. Based on the measured parameters value the quality of the egg and its expiring day will be displayed for consumer.
