Menengiç Meyve ve Tohumlarının Fiziksel, Mekanik ve Kimyasal Özelliklerinin Belirlenmesi

In this study, the physical, mechanical, and chemical properties of terebinth fruits and seeds were determined. The fruits were obtained from a herbal market locating in Tokat, The experiments conducted in Tokat Gaziosmanpaşa University, Agriculture Faculty, Department of Biological Engineering, Biological Materials Laboratory. The volume of terebinth fruit and seeds were measured 0.08 cm3 and 0.043 cm3, 100 fruit weight and 1000 seed weight were determined as 9.25 g and 0.442 g, respectively. The porosity rates of fruit and seeds were found as 51.33% and 21.73%, respectively. The color characteristics such as chroma and hue angle of the fruits were found with 2.51 and -1.17 and for terebinth seeds chroma and hue angle were as 9.39 and 0.75, respectively. For terebinth fruits, the rupture force increased in Y- and Z- axes compared to the compression speeds, while for the seeds, the rupture force decreased in the X-, Y- and Z- axes. While the friction coefficient was found on the plywood surface with the highest value of 0.514 for the fruit, the lowest value for the seed was found as 0.314 on the laminate surface. Among the chemical properties, pH, titratable acidity and water-soluble solid content were found as 5.70, 1.61 g 100 g-1, 3.14%, respectively for fruit, while the values for seeds pH, titratable acidity and water soluble solid content was determined as 6.49, 1.84 g 100 g-1, 3.60%, respectively. The physical, mechanical, and chemical properties of the terebinth fruit and seeds can be taken into account during the design, and operation stages of machinery and systems used in post-harvest production technologies.
