| Abstract: |
| The surface area of the egg is an important factor in determining gas and water exchange through the shell, and many methods have been proposed to estimate it. The surface area of the egg is estimated by profiles and matching the shape of the egg with mathematical relations and then calculating the surface of the rotation. The methods for determining the surface area of eggs are either very complicated and difficult, which cannot be used for a large number of eggs, or they are very simple, so that they cannot provide an accurate estimation. In this research, a different experimental method for estimating the egg surface area has been presented and compared with other methods. This method is destructive and the surface area is obtained through the ratio of the volume of the egg shell to its average thickness. To determine the volume of the shell, the volume of the whole egg was subtracted from the volume of the yolk. After determining the surface area of the samples, it was finally found that the values obtained with equations (1) and (6) had a higher correlation than other equations, and as a result, the equation S=5.01 W^(O.6518) with a correlation coefficient of 0.8587 and the equation S=6.2581 V^(O.6037) with a correlation coefficient of 0.8496 is suggested to determine the surface area of eggs. |
