These are closed shell pistachios that have been mechanically opened along the suture of the nut to look similar to the naturally open pistachios. The difference with naturally open pistachios is a lower kernel weight to in-shell ratio (kernel content). Good quality MOs can have kernel content of 49-50%. MOs are used as snacks. On average, over 10,000 tons of mechanically opened pistachios are exported from Iran each year, with a total value of about USD 80 million. The top three markets for this product are: the EU, the Middle East and CIS countries.
