Selected mechanical properties of pomegranate peel and fruit

Abstract

Mechanical property data of pomegranate fruits are limited. The objective of this study was to determine the compression and cutting properties of whole fruit as well as the puncture strength of peel samples of fruit at different storage times. The results showed that storage time had a significant effect on all the properties studied in this work except for peel shear strain (p < 0.05). The whole fruit cutting energy and power, maximum cutting force, peel shear strength and strain and shear modulus showed an increasing trend with storage time. However, firmness, bioyield force, and modulus of elasticity increased and then decreased with storage time. Copyright © Taylor & Francis Group, LLC.
