The chain of 26 Aulds Bakeries has been put into liquidation by its owners, meaning 180 jobs are at risk.
Founded 118 years ago, the family firm says its retail business has been losing money as a result of supermarket competition and rising wage costs, according to the BBC.
The bakeries in Greenock and Inchinnan near Glasgow Airport will continue to operate and supply other shops, safeguarding 200 other jobs.
Liquidators say the shops will continue trading as they search for a buyer.
A spokesperson for Aulds said: “Like many high street businesses, we’ve found trading extremely tough in recent years, with pressure from the high street and supermarket competition, as well as increasing ingredient, distribution and wage costs. All of this has meant the retail business has been making a loss, which we can no longer sustain. We have spent several months trying to find alternative options but unfortunately, this is the only way of protecting as many jobs as possible.”
The company will continue to supply bakery products to Scotmid stores and other independent outlets where they are currently sold.
