Swelling and pore structure in starchy materials

The specific surface areas of different starchy materials were determined by means of the t-method, their values being practically constant in the range of water activities 0·10-0·80. The straightness of the v1-t plots observed in all cases indicated the absence of an intrinsic microporous structure...
