Troyano’s agent, Anne Kibel, announced the news on Twitter.
“Sadly, my lovely client lost his brave fight against oesophageal cancer last week,” she said.
Troyano, a Manchester-based graphic designer, appeared on the baking competition series when it was on the BBC back in 2014.
He finished in second place behind Nancy Birtwhistle.
Following his time on the show, Troyano published a book titled Bake it Great.
He also made regular appearances BBC’s Good Food channel.
Troyano’s wife, Louise, has created a Just Giving page to raise money for Macmillan Support.
She paid tribute to Troyano, writing: “Your life was a blessing, your memory a treasure, you are loved beyond words and missed beyond measure.”
Nadiya Hussain, who won GBBO in 2015, also paid tribute to Troyano. Sharing Kibel’s Twitter post, she wrote: “RIP X."
In 2018, Troyano put the apron he wore in his finale up for auction via Stand Up To Cancer.
“Now let's be clear here, this apron has NOT been washed since it was worn in the final and has the showstopper stains, sweat and smell of the tent on it!” he wrote in the post accompanying the donation.
“I'll shed a tear the day this leaves me but I know it’s for a great cause.”
He decided to auction the item in memory of his father, who died of cancer when Troyano was 16 years old.
