Inulin has the ability to form inulin microcrystals due to its long chain length, when sheared in water. or milk. These microcrystals interact to form a creamy texture [ 13 ] And possibly increased the hardness of ice cream. On the other hand, increases in hardness of reduced or low-fat ice creams containing WPI or inulin may be related to. decreases in freezing points as a result of higher solute con-. centrations. The addition of 5% inulin to low-fat ice cream. [ 28] or 5% modified starch to low-fat yog-ice base [. 16] increased the hardness in comparison to high fat control. sample.
