| Abstract | Glass transition behavior, adsorption isotherm and crystallization of isomalt-hydrogenated starch hydrolysate (HSH)mixtures (0-20% HSH) and pure HSH were investigated. At similar solid content, Tg decreased as HSH concentration increased.Tg data at different solid contents were well-fitted with Gordon-Taylor equation (R2?0.97). Adsorption isotherm showed thatsystems with greater HSH concentration became more hygroscopic. Accelerated storage test (30?C, 84% RH) of modeledhard candy containing 10% HSH and pure isomalt formula was done. HSH enhanced water uptake and crystallization ofpolyols in hard candy during aging without packaging; however, those effects were lessen for the samples aged in polyethyleneterephthalate/cast polypropylene (PET/CPP) pouches, and were negligible after the application of superior moisturebarrier, oriented polypropylene/metalized cast polypropylene (OPP/MCPP) film. Although HSH adversely affected storagestability of sugarless hard candies, it could be add into the formulation together with the application of packaging havinga good moisture barrier. |
