Edinburgh-based Mademoiselle Macaron and COCO Chocolatier, as well as Isle of Skye Candle Company, will open units in the departure lounge.
Award-winning Luckie Beans coffee roasters will also be opening a coffee cart at baggage reclaim in International Arrivals 2.
The airport's director for retail and property, Gail Taylor, said: “We’re extremely excited to be welcoming even more Scottish suppliers to our range, especially after the success of the world’s first BrewDog airport bar.
"It’s a fantastic opportunity to showcase the fantastic food and drink we have to passengers from across the world, and show we are an airport of provenance. We’ve made a real effort to work with Scottish retailers when expanding and increase choice for passengers.”
Calum Haggerty, director of COCO Chocolatier, noted: "Hand-crafted in Edinburgh, our chocolates are inspired by art and showcase original, contemporary designs by artists.
"We are excited to be able to offer travellers passing through Edinburgh Airport a varied selection of our hand-crafted chocolates.”
While Jamie McLuckie, founder of Luckie Beans, said: “We are so proud to be offering our Great Taste Award Winning coffee to those arriving into Edinburgh - being the first coffee they can try in the city will hopefully fill them with high expectations for their visit!”
Rachel Hanretty, founder of Mademoiselle Macaron, enthused: "I learned how to make French macarons while living in Paris and always wanted to bring a little bit of France back with me.
"To now be able to truly deliver that to people before they have even left Scotland is an exciting moment for us.
“To have grown from a local market stall to an industrial kitchen making tens of thousands of macarons by hand with an amazing team in just a few years is something I am yet to believe but am extremely proud of.”
