The work on Tenderstem was funded by the main licence owner Coregeo, prompted to capitalize on 16% year-on-year growth into the vegetable’s health properties.
Tenderstem broccoli contained twice the vitamin C content of the equivalent fresh weight of oranges and had a higher concentration than cauliflower and cabbage.
No other type of broccoli had higher levels of carotenoids than Tenderstem, making it good at protecting against cancer and heart disease.
Tenderstem broccoli contains one of the highest levels of folic acid of the brassicas tested in the study and was 25 to 30% more tender than purple sprouting broccoli.
UK production will this year account for 25% of sales of Tenderstem, which requires less cooking than other broccoli, therefore retaining a high proportion of nutrients.
Tenderstem is a cross between broccoli and Chinese kale, licensed in the UK to Coregeo UK Ltd. Several British businesses have licences to grow Tenderstem.
