Blanching is a short heat treatment that is typically
applied to vegetables prior to further processing with
the aim of enhancing both safety and quality attributes.
It imparts benefits such as the destruction of surface
microflora on vegetables and the enhancement of the
color, texture and also the keeping quality of vegetable
products (Jaiswal et al., 2012c). In addition, blanching
is essential for vegetable products destined for further
storage such as freezing or drying in order to inactivate
certain enzymes including lipoxygenase, polyphenololoxidase,
polygalacturonase, and chlorophyllase which
are associated with losses in quality and nutritional properties.
Apart from blanching, other processing methodologies
of vegetables, including drying and freezing, are
insufficient to inactivate these enzymes thus leading to
deterioration in texture, color, and flavor during storage.
