Tajeddin, B., Agricultural Engineering Research Institute (AERT) Karaj, Iran
There are many factors that they are unsuitable for walnut kernel storage such as not or bad packaging. In order to effect of walnut kernel packaging on the its quality and shelf life, after walnut dehulling, they dried in expose of sun and by using an air-dryer machine till its moisture content was reduced to 6%. Walnut kernels packaged in plastic films including PVC, LDPE/PA/LDPE and PA/PP. Packaged samples were storage in ambient temperature. The quality characteristics such as acidity content, peroxide value, iodine value, kreis test and presence of microorganisms especially fungi were studied in storage time. The results of our analysis showed that: LDPE/PA/LDPE and PA/PP films were better than PVC film and control. LDPE/PA/LDPE was better than PA/PP with little difference. Use of vacuum packaging was better than control. Use of machine drying was better than sun drying with little difference. Keywords: Packaging, Polymer Films,Walnut
