McCain Gastro Chips also won the gold award for the Best New Accompaniment-Potato-Vegetable Product, with the company's Sweet Potato Fries taking the silver award in the same category.
The Gastro Chip was launched earlier this year in response to strong demand for a consistently great tasting, premium chip that is quick and convenient to prepare and helps to reduce waste and preparation time.
"The BFFF Awards celebrate the very best in frozen food, so we are delighted that McCain Gastro Chips have been recognised with the top prize," said Mike Driver, head of marketing for McCain UK. "Listening to our customers is crucial to our business and a huge amount of work went into the trial and development of Gastro Chips to ensure we were giving chefs and their customers exactly what they want.
