The advisers will also evaluate alternative plans including the issuance of a bond, two of the sources said.
The group hopes to raise funds on the financial markets next year, but it needs first to appoint a new chief executive and streamline its organisation, the two sources said.
The company is wholly owned by the De Ceccos and run by two chief executives and a chairman picked among the different branches of the family.
De Cecco, which also sells olive oil, pasta sauce and rice, had considered a bourse listing more than 10 years ago, but the plan was put on hold when the global financial crisis erupted in 2008.
Its revenue rose 5.7 percent to 448 million euros (£395.2 million) last year, with core earnings up 18 percent to 48.8 million euros.
