Rice is commonly used for puffing purpose due to its taste,
texture and nutritional profile. Puffed rice is a popular snack
product prepared by parboiling the paddy under the specified
conditions followed by high temperature short time treatment of
the parboiled rice in hot air or sand (Chinnaswamy &
Bhattacharya, 1983; Murugesan & Bhattacharya, 1991).
