Abstract

Physical modification of starches using dry heating, gamma and electron beam irradiation are considered greener and more cost effective than using crosslinking chemicals for starch modification. Chemical modification of starches generates lot of downstream waste. Alternatively, dry heating of starches can also be utilized to influence hydrolysis as well as crosslinking of chains and requires no catalyst. Gamma and electron beam irradiation although used largely for preservation of foods can introduce carboxyl groups into starch molecules as well as degrade starch chains. Gamma and electron beam irradiation can hydrolyze as well as
cross link starches which can have various applications in food and process industries. Irradiation and dry heating are promising techniques and can be used in conjunction with other modifications type for making specialty and resistant starches. To the best of our knowledge dry heating of starches has not been reviewed. Need was also felt to critically review irradiation techniques since there are many ongoing debates on its implications.
