Determine the Tomatoes Volume

Abstract

The aim of this research is to obtain a quick and low-cost method for measuring the volume of tomatoes for small farmers, which have limited access to new technology. This measurement will help in grading, packaging size, and transportation costs. Weight loss of the tomatoes relates to their shelf life, which is between 5-7%; within this range, the tomatoes are still edible. This research attempted to find a relationship based on the volume of tomatoes in an elliptical spheroid using the water displacement method. The samples included 15 tomatoes chosen randomly and weighed, and then the height and width were measured. Tomatoes weight in water and water high with tomatoes were measured and then the different calculated, which represented the volume. The results illustrated that the linear regression model explained 80% of the data. The tomato shapes may help in the weight loss and firmness of tomatoes during storage for further studies.
