Workers at the collapsed company Gourmet Food Holdings, which produces Rosella tomato sauce, may be able to keep their jobs after receivers expressed more confidence that the business would be sold and the 100-year-old brand would continue.

Ferrier Hodgson, receivers of the company that went into voluntary administration last week, said they had received close to 100 expressions of interest from potential buyers considering purchasing all or part of the business.

“If we continue to receive this valuable support from customers, suppliers and transport operators, the business should be able to continue operating and employees will keep their jobs,” partner Jim Sarantinos said.

“Given the level of interest in the business amongst potential buyers, I have an increasing degree of confidence that the group has a future.”

Mr Sarantinos said all employee entitlements were likely to be paid in full regardless of whether the business was sold, but a sale was "key to the long-term future of the business".

Ferrier Hodgson partners Steve Sherman, Mr Sarantinos and John Lindholm were appointed receivers of Gourmet Food Holdings on Monday.

The group also incorporates New Zealand organic foods group Pitango and Victorian-based biscuit group Waterwheel.

The Rosella factory in Seven Hills, NSW employs 110 staff, 47 of whom are contractors. Waterwheel, in Dandenong, Victoria has 140 staff, 69 of whom are contractors.
