Paula Deen, the self-proclaimed queen of Southern cooking and a sugary mainstay of the Food Network, was dropped by the network on Friday, after a bewildering day in which she failed to show up for an interview on the “Today” show and then in two online videos begged her family and audience to forgive her for using racist language.

A network spokeswoman said it would not renew Ms. Deen’s contract when it expired at the end of June. Ms. Deen has faced a volley of criticism this week over her remarks in a deposition for a discrimination lawsuit by a former employee. In the document, she admitted she had used racial epithets, tolerated racist jokes and condoned pornography in the workplace.

The Food Network statement did not elaborate on its reasons for dropping her, but a person close to the network said its shows featuring her sons, Jamie and Bobby, would not be affected. Ms. Deen currently has three regular programs on the network, including “Paula’s Best Dishes.”
