This month, a special kind of apple slice will go on sale at select US supermarkets and, thanks to CSIRO research, these apples won't turn brown when they're cut, bitten, or bruised. Arctic apples have been developed by an innovative Canadian biotech company and their first product will be bags of fresh non-browning Arctic Golden apple slices. While there are other sliced apple products already on the market, these are often coated with vitamin C and calcium to prevent browning and to preserve crispness, and this can change their taste.
