Ross Finnie will be chair of FSS and Geoff Ogle as chief executive of the group which will be established in January 2015 when the Food (Scotland) Bill receives Royal assent.
Finnie is currently a non-executive member of the Water Industry Commission for Scotland and the Greater Glasgow and Clyde Health Board.
He said: “Food Standards Scotland will be firmly committed to protecting the interests of consumers, placing science and evidence at the heart of what it does.”
Ogle has been Acting Director Scotland for the Food Standards Agency since June 2014.
He said: “I will ensure Food Standards Scotland continues to provide independent, evidence based advice to consumers and Ministers and plays an active role in furthering the invaluable work carried out in Scotland as a whole.”
FSS will have a budget of around £20m per year and be staffed with 90 HQ staff in Aberdeen and 70 in the field.
