Perthshire Bake Off star Flora Shedden has warned that a move to Channel 4 will “ruin” the show.
The Dunkeld baker was responding to news that the current series of the hugely popular cooking contest would be the last on the BBC.
Love Productions, which makes the programme, parted ways with the corporation in a row over money.
The BBC is reported to have refused to pay £25 million to keep the programme.
Flora, who was a favourite in the 2015 series, took to Twitter to voice her disappointment.
She wrote: “Really sad to hear that the BBC has lost rights to Bake Off.
“Its success is down to format and aesthetic – commercialising will ruin that.”
The 20-year-old St Andrew’s University student landed a lucrative book deal after her stint in the competition.

It is not clear whether judges Mary Berry and Paul Hollywood will move to Channel 4.
Just months ago, Hollywood said that he and his co-stars would prefer to remain on the BBC.
He told Chris Evans on Top Gear: “I’ve said, I think the girls have said as well, we want to stay with the BBC. As far as Mary, Mel, Sue and myself, we want to stay.”
A source for Love Productions told The Sun: “Everyone is used to Paul, Mary, Mel and Sue being a part of the show.
“Love can’t foresee a show without them, but also they never could imagine leaving the BBC.”
A BBC spokesman said: “We made a very strong offer to keep the show, but we are a considerably distance apart on the money. The BBC’s resources are not infinite.”
Last month, Flora spoke about her “crazy” year since appearing in the show.
She added: “I’d bonded with the other bakers over dinner at the hotel but we didn’t meet Paul and Mary until they walked into the tent to judge us on the first day.”
Flora flew back to Scotland after every two days of filming, often not getting back until 3am.
“By the time the semi-finals came round I was totally exhausted,” she admitted.
“There was a bit of disappointment at not making the final but I was secretly thrilled that I could go to my bed and get a good sleep. I probably didn’t do as much practice and preparation as I should have and that might have made a difference.”
