Abstract:To investigate the effect of storage temperature on the aging characteristics of toast,the changes in the toast were measured in terms of textural properties,moisture content,moisture migration,aging enthalpy,and aging rate at different storage temperatures （-18,4,10,15,20,25 ℃）.It was found that the toast aged fastest at 4-10 ℃,where the toast after storage had the worst textual properties,with limited moisture migration,greater moisture loss,aging enthalpy,and aging rate.As the storage temperature increased,the toast showed good aging resistance.However,according to all the results together,the maintaining effect of the toast quality was more effective more significant by frozen storage at -18 ℃.
