Abstract

Tomatoes are one of the most important food products in human nutrition that are consumed by millions every day. It is considered as one of the most valuable products of vegetable and seafood, which is second only to potatoes economically. Tomatoes are rich in vitamins. The fruit is used today in many different ways, as raw or as one of the necessary ingredients to prepare meals, sauces and include an important part of the diet of people in many countries. In this study, some of the mechanical properties of tomato have been extracted. The samples under compressive force at speeds of 20, 60,100 and in stages of immature, half mature and mature were tested which is a simple way but very efficient. The results showed that the toughness of the fruit decreases at different speeds. In the Immature fruit the energy decreases at a speed of 20. The energy also increases with increasing speed. The energy is also reduced in the half-mature fruit with increasing speed. The energy is reduced in mature fruit with increasing speed. The toughness in the fruit decreases at different speeds. The rupture force is reduced in immature fruit at speed of 20 mm/min. The rupture force also decreases with increasing speed. In the half- mature fruit, the rupture force also decreases with increasing speed.
