Abstract: | Due to magnitude of geometric characteristics of the egg in agribusiness, this research was performed aiming to experimentally validate various mathematical models of volume and surface area of eggs, using adjusted and literature empirical equations in order to improve the accuracy of calculation of these parameters. For this reason, 450 samples of eggs were collected: 150 chicken eggs (white), 150 chicken eggs (brown) and 150 quail eggs. Each egg was weighed and its dimensions (length and width) were measured using a digital caliper. The real volume of each egg was determined by immersion in water. The surface area and volume, the samples were obtained using adjusted empirical equations, and from computational methods and the literature. Based on the results, the brown eggs have weight, volume and surface area significantly higher than white eggs and quail eggs . Overall, all models to estimate the volume and surface area of eggs, proposed in this paper and from published research, showed mean values close to real. The image analysis eggs, which is neither invasive nor destructive, a good alternative to the conventional destructive methods. |
