The company launches on 1 June and will provide comms advice and support to restaurants, hotels, food and drink brands as well as campaigning on food issues.
Jardine most recently presented STV’s tea-time show The Hour, and also presented the CIPR Scottish Pride awards last year.
He has also been GMTV’s Scotland correspondent, STV’s host of the Millennium Hogmanay Show and had his own evening chat show Tonight at the Top.
‘Broadcasting has been a great business for me but my real passion is food and drink,’ said Jardine.
He added: ‘I recently spent a year eating only Scottish produce and learned just how important the industry is to our economy and our sense of national identity. We have some brilliant individual businesses but they need help to spread the message that Scottish food and drink is the best in the world. I’ll use my contacts and understanding of how the media works to do just that.'
