Table Grapes Transport Simulation Study by Bardas (Vitis vinifera L.) Cultivar Grown in Karaman Turkey
Table grapes is a second industry in viticulture in Turkey and have been grown in primarily Mediterranean region a popular fruit for local consumption and export to many European and Asian countries as a fresh dessert and for this reason this product has to be transport so long distances for marketing. This simulated export transit experiment with Bardas (Vitis vinifera L.) local table grape cultivar grown in Karaman province was conducted in lab condition Selcuk University Faculty of Agriculture. To produce main knowledge, and to improve the application of resources used to produce, pack, transport, and merchandise Turkish table grapes by increasing efficiency, controlling cost and managing risk throughout the supply chain. In order to develop optimized methods of reducing table grape damage transport stimulatory as vibration stimulator have been used to measure the shocks and vibrations in market bins during 30 min and 60 min transport stimulation. During road transport simulation at 25°C in wooden boxes damages of clusters and berries were measured by laboratory trials to stimulate the events in a controlled and repeatable manner. 3 bins full of fruits were placed onto a vibration table, and during the stimulation three-load profile sensor were placed inside each of bins. While the number of separated berry was determined as a 31.33 in 30 min, the number was 83.10 in vibration period of 60 min. Starting with the beginning the numbers separate resistance of berry, resistance to cracking of berry and elasticity modulus is continuously lowering in 30-60 min vibration periods. The berry separate resistance from cluster were changing between 4.46 N to 1.73 N, and berry cracking resistance were measured between 31.59 N to 26.01 N, and berry elasticity modulus were obtained as between 1423 kPa to 1076.7 kPa. Natural frequency of berry was calculated as on 109.332 Hz that was obtained in of 1.42 m box height.
