Heinz ketchup and Hellman’s mayo will not be united under one corporate roof.

3G Capital, the giant Brazilian private equity firm that controls Kraft Heinz, is not interested in making a second run at London-based Unilever, two sources close to the situation told The Post.

Kraft Heinz saw its $143 billion offer for the Hellman’s brand owner rebuffed in February because it was too low. But the UK’s six-month ban on making a second takeover attempt expired on Aug. 19, freeing Kraft Heinz up for a second run.

Despite speculation that Kraft Heinz would try again, perhaps with an offer of roughly $200 billion, 3G brass are no longer interested in the mammoth consumer-products company.

“Nothing is coming at the moment,” a source close to the situation said. “I would be surprised if they approached Unilever again.”

A second source who also has direct knowledge of the matter was more definitive, saying Kraft Heinz was done with Unilever, whose brands also include Dove, Vaseline and Lipton.

3G is not interested in pushing a hostile bid. That was made abundantly clear on Aug. 30 when Warren Buffett, who owns a 26 percent stake in Kraft Heinz, told CNBC that the company “will not make hostile takeover offers.”

It is not clear who Kraft Heinz might target instead — but Buffett, in the TV interview, said it would not be Mondelez.

“They are not in any rush to make a deal,” one of the sources said.

On Friday, Kraft Heinz named former Goldman Sachs banker David Knopf as its new CFO.

A 3G spokesperson declined comment.
