Freelance photographer and filmmaker Salima Kamara, 27, is charged with attempting to murder Oshane Campbell at their shared home on Bracondale Road in Abbey Wood.
Police were called to the address on April 7 after allegations were made that bleach had been added to a number of food products, police said.
The man, 31, was taken to hospital but did not receive any life-changing or life-threatening injuries.
Kamara appeared at Woolwich Crown Court on Wednesday, May 7, where she pleaded not guilty.
She was released on bail until her trial in August 2027.
Kamara was given conditions to reside at a house in Beckenham belonging to her aunt, who offered a £10,000 surety payment.
She was also given conditions not to contact the complainant or any potential witnesses in the case.
