Apples that do not brown for 3 weeks to go on sale in Feb
Genetically modified apples that do not oxidise or get brown for three weeks after slicing, will go on sale in Midwest in February. Developed by Canadian company Arctic Apples, the feat was achieved by 'silencing' polyphenol oxidase (PPO) expression. These non-browning apples and their trees grow in orchards just like the non-modified ones, the company said.
