(2) stabilise the colloid and prevent crystallisation Explanation: Gelatine, being a colloid, has the property of preventing crystallization. In ice lollies and icecream this is demonstrated by the formation of a very fine crystal structure on freezing. This goes much further in that gelatine stabilized icecream does not become grainy or sandy due to the slow crystallisation of lactose with time.
