US snack maker Diamond Foods has unveiled a line of “all natural” Kettle tortilla chips in its first major launch since purchasing the crisp maker earlier this year.

Kettle Brands Tias will be available from next month in six flavours; Salsa Picante, Zesty Ranch, Nacho Cheddar, Toasted Corn, Sweet Baja Barbeque and Chili Con Queso.

The line, Diamond Foods claimed, is made using certified organic corn, expeller pressed oil and all natural seasonings.

"Kettle Brand Tias is a strong opportunity for our company to leverage the innovation strength of the Kettle brand and place it into an adjacent segment,” said Michael Mendes, chairman, president and CEO of Diamond Foods. “The natural tortilla chip segment is 40% larger than the natural potato chip segment.”

In May, the company extended its Emerald and Pop Secret lines.
