A UK firm pioneering the use of electrostatics to apply flavourings to food has seen sales grow by 25% this year as food manufacturers have started to embrace the technology.

By applying a static charge to powdered seasonings or oils while they are being sprayed onto snacks or sweets, firms can gain superior, uniform coverage as the 'charged' flavouring is attracted to the products.

As firms using electrostatics typically used 10% less flavouring compared to traditional 'tumbling drum' methods, which generated a lot of waste, most saw a return on investment within four months, claimed Oxfordshire-based Spice Application Systems (SAS)

While SAS has won business with Intersnack, Burt Chips and Seabrook Crisps in the UK, most of its sales were in Continental Europe, with growing interest in the US and Middle East, said md Peter King, who has now sold more than 1,000 units.

"It's frustrating that some UK firms have been unwilling to even trial the technology. This has amazed firms in other markets who have seen a payback." Firms can trial the technology at SAS's test facility or rent it before deciding to buy. The kit can also be retrofitted to drums on existing production lines and will work with all types of pump and screw feeders.
