Determination of some physical and mechanical properties of two walnut varieties
For efficient processing operations and proper designing of machines and processes, the better understanding of the product is needed. The aim of this work was to evaluate the physical and mechanical properties of two walnut varieties (poost-kagazi and poost-sangi) from Osku city in East Azerbaijan province in September 2014. For this purpose, length, width, thickness, volume, sphericity, surface area and geometric mean diameters of whole and kernel walnuts were determined. Moreover, compression and penetration tests were done for both of varieties stored at three different temperatures room (25 ˚C), refrigerator(4 ˚C) and fridge(-18 ˚C). Walnuts kernels were packaged in polypropylene pouches during storage. The result showed that sphericity of walnut is depends on its variety. The results of one-way ANOVA showed a significant the effect of variety on the sphericity (P
