South African company Green Cell Technologies claims to have created a super-antioxidant extract from tea with an Oxygen Radical Absorbance Capacity (ORAC) value of 1,700,000 per 100g. This is the highest known commercially extracted ORAC value from any plant material and could be a radical breakthrough in antioxidant health supplements.
According to Beverage Daily, the company says its Dynamic Cell Disruption method has enabled it to produce these green tea and rooibos tea extracts. This destabilises the structures of the plant cells and releases all of the actives instead of just part of them.
Green Cell Technolgies think they have found a way of relieving the body of free radicals with fewer cups of green or rooibos tea. However, Dr. Jorg Grunwald, president of natural products consultancy analyze&realize, has said that the results need to be verified because they seem very high:
Brunswick Laboratories is the only lab recognised as performing legally acceptable ORAC measurements. The range given is practically unbelievable – only spices have been shown to deliver ORAC values of 300,000.
