Compass Group UK & Ireland's healthcare businesses, including Medirest and WhiteOaks, have raised £50,000 for the Alzheimer's Society in just under eight months.
The money will help support the charity carry out research into the link between food and dementia.
Compass will continue with its fundraising efforts to support the £151,000 required to fund the research, which will be led by Lindsay Collins, an Alzheimer's Society clinical fellow at the University of Bradford.
Fundraising initiatives included a penalty shootout with Compass Group's managing director Dennis Hogan and the managing director of healthcare Steve Cenci in goal, which raised £2,500.
A Christmas Jumper Day held by the healthcare retail team raised more than £25,000 and a further £2,084 was raised in a series of fundraising activities organised by Housing & Care 21 sites in Kent.
The partnership between Compass and the Alzheimer's Society has introduced 1,000 Compass employees to the Dementia Friends programme, which aims to transform the way the nation thinks, acts and talks about the disease.
Cenci, managing director, healthcare, Compass Group UK & Ireland, said: "We are pleased to be supporting the Alzheimer's Society in its critical research on the effects of dementia on eating and drinking. This unique study will provide recommendations to enable care professionals and families to ensure that people living with dementia and dysphagia can receive better care and have a better quality of life.
"It is a great achievement to have raised £50,000 in such a short time and we remain focused on raising even more funds to ensure this important research can be completed."
Jeremy Hughes, chief executive of the Alzheimer's Society, added: "Compass employees have shown unwavering enthusiasm and dedication in their fundraising efforts, and we are extremely grateful for their support in our fight against dementia."
