Steaming is one of the common processing steps in fruit and vegetable processing. In general, it has been shown to cause an overall increase in antioxidant capacity, and in particular an increase in phenolic compounds has been seen. This can be explained by the inactivation of oxidative enzymes that have the ability to oxidize phenolic compounds. Steaming also relies on the non-direct contact of the products with water, which prevents the solubilization of water-soluble compounds such as ascorbic and anthocyanins. As seen in Table.10.1, steaming can be regarded as a better cooking method (when compared with boiling ) for increasing the bioactivity of vegetables.
