A commercial court in northwest France is set to evaluate the bids at a hearing on 23 July 2012.
The administrators had earlier scheduled the bidding round deadline to 5 July , as a part of an effort to save the firm, which has been burdened with a debt of € 340m.
Doux chairman Charles Doux noted that he plans to make an alternative proposal over the coming days to help continue the company's operations at least until December.
La Financière Turenne La Fayette had offered €25m for two plants, Terrena had made bid of €24.7m for three plants, while Tilly-Sabco put forth an offer to takeover the export operations of Doux, which include two plants and thereby secure 588 permanent jobs.
However, unions at Doux were unhappy with the offers and noted that the bids would cover only a few sites and would dismantle the company, a concern shared by the French government too.
Earlier, Sofiproteol through its subsidiary Glon Sanders led a consortium featuring the following companies - Terrena, Triskalia, Duc, Tilly-Sabco and LDC, to submit a joint bid, and noted that each company involved will gain control over a part of the activities following the acquisition. However, the composition of the consortium changed, with Terrena Tilly-Sabco and LDC bidding separately, leaving Sofiproteol with Glon Sanders, Duc and Triskalia.
