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...

520 3 |a 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. The lack of a pore structure and the high values of the specific surface areas are explained on the basis of the interlamellar expansion of the starch granule structures on uptake of water. © 1989.  |l eng
