The market for salted snacks in the US has grown at an annual rate of over 7% since 1997, thanks largely by a growing trend of product innovation; of tweaking existing products with new flavours, shapes and textures to reignite consumer interest. Packaging trends, including convenience size products, are also serving to energise a flagging market, according to the US Market for Salted Snacks report published by MarketResearch.com. Americans are far more time-pressed today than they have been in the past, and the current popularity of conveniently packaged foods attests to the ways in which this time crunch has altered dietary habits.
