In steam blanching the product is carried on a belt through a steam chamber into which live steam is constantly injected. 6. Moreover, steam blanching required more energy (53.93 ± 1.24 kJ mol −1 ) than hot‐water treatment (41.41 ± 4.51 kJ mol −1 ) to reach the transition state and then to unfold the PPO enzyme. The aim of the storage study is find the influence of temperature and storage periode on vitamin C, antioxidant activity value, water content, texture, and colour of broccoli. x���nG�݀�aI@O�3�0D�cd7 ����}0MY�Ƣ��&A�����guO�9\��>����b��}�����n~yS5�~����V?����v}uU]����?�|��gRY}��������5m��5i���/_4�|�{����z�W���Z_�����a-W���n����?_�x��`���1�O� Blanching is achieved in hot water for a short period of time or in an atmosphere of steam.
