摘要: Summary Sorption isotherms of proteins different origins and heat treated the same origin were studied at 5, 15 25°C. Differences in sorption related to differences swelling solubility. A soy protein isolate, a sodium caseinate whey concentrate studied. It was found that low intermediate water activities (aw) increased with ability swell take up liquid water. At high aw where solvation process starts, could be as well temperature or independent range 0.4–0.6. In this range, pronounced minima rates found.
