Macphie has launched a new range of premium finishings called i-zings. They are made from 100% natural colours and flavours and are available in four "zingy" flavours: summer fruits, orange, pineapple and lime.

The ingredients manufacturer suggests using the i-zings to bring a tropical taste to products such as cupcakes, doughnuts, muffins and traybakes.

"Colour blocking is a key fashion trend for summer and you can make the most of this on your shelves with ready-to-use i-zings, saving you time and ensuring great results time after time: simply heat and get creative," said marketing manager, Jania Boyd.

The i-zings are available in 5kg pails. To celebrate the launch Macphie is also offering bakers the chance to win the latest i-phone 4. For full details visit
