Indian spice brand Kitchen Guru said it had signed several definite orders at the Expo and had leads ranging from small retailers to the multiples.
"It has been much better for us than two years ago," said MD Chandra Parmar. "We've redesigned our packaging and relaunched the range, which helped get people interested."
Milkshake brand Shaken Udder said its Expo debut was a success, with keen interest from wholesalers and indies. "As a new brand it's important for us to be seen at a show like this," said director Andy Howie.
While the Expo's first day was a Sunday and so busier with the public, The Garlic Farm said quality leads picked up from Monday.
"As we're based in the Isle of Wight, the show lets us meet existing customers face to face," added marketing chief Darren Rayner.
The show, organised by William Reed, publisher of The Grocer, was host to more than 600 exhibitors.
Exhibitions director Neil Felton said: "The mood of visitors and exhibitors was incredibly positive and indicates that we may be turning the corner."
