ABSTRACT
Sugar-milkfat composites with syrup consistency were prepared from sucrose, maltose or high fructose corn syrup and butteroil (20 to 40%). The components were homogenized at 40% solids and evaporated under vacuum at 60C for 60 min, leading to the formation of syrup composites with ordered structures. The viscous behavior of the syrups was described by a power law model. Flow behavior indices (0.3 to 0.9) indicated mostly pseudoplasticity, with Arrhenius-type response in consistency and flow behavior index. The sugar/butteroil composites could be microwaved to < 20% moisture in approximately 60 s, producing toffee-like candies of varying color and consistency.
