Savencia said Delamea's mission will be to lead the company in the next steps of its development, with the help of the teams in place, while respecting its culture and independence.
Torris is set to retire after 30 years with the company, and as CEO since 2016.
The board, chaired by Alex Bongrain, paid tribute to him for the consistency, scope and quality of his contribution to the success and development of the group.
Torris will continue in the role until September 1, and will work with Delamea during a transition period.
Delamea joins Savencia in April, after having headed the vegetable division of the Avril Group. He started his career within the Danone Group, including as general manager of Danone France.
"Together with the entire board of directors, we are pleased to welcome Olivier Delamea as the new chief executive officer of Savencia Fromage & Dairy. We are convinced that he shall be able to lead and motivate the Group's teams in order to pursue, with them, our sustainable growth and strengthen our position as a leading player in the dairy sector, in the context of our mission "Leading the way to better food". I wish to thank Jean-Paul Torris for his remarkable contribution to the development of the group, and for his support to Olivier Delamea in his new role," said Bongrain.
"I wish to thank Alex Bongrain and the Board of Directors for entrusting me with the General Management of the Group during these years. I am proud to have supported its humanist culture, deployed a sustainable growth strategy in France and internationally. I wish to salute all the teams for their commitment, it is with them that we have been able to develop the Group successfully. I am pleased to welcome my successor Olivier Delamea and wish him and all the Group's employees full success in continuing to promote and develop Savencia," Torris said.
"It is with enthusiasm and pride that I join Savencia, a family-owned and listed food group, committed to a genuine long-term heritage project. Together with our teams, we shall continue to develop a portfolio of high-quality products and strong, unique brands, and shall continue to defend a positive vision of food that combines pleasure and health. The mission and values of the Savencia Group are major assets in an environment where our industry needs to address the challenges of food, agricultural and environmental transitions," Delamea said.
