摘要：

This work reports that the parameter k (factor correcting the properties of the multilayer) in the GAB sorption equation varies from nearly unity to as low as 0.56 for a large variety of food constituents and related materials. Values of k for proteins fall in a relatively narrow range of 0.82-0.88 (average 0.84 +/- 0.03 SD), while for starchy materials they fall in the range 0.70-0.77 (average 0.74 +/- 0.03 SD).
