Ibn Hazm put it concisely when he said,

“Ruling upon an object is upon what it is named (what it is), if the name (what it is) changes then so does the ruling.”

He also mentioned in his book of fiqh, Al-Muhalla: “If the quality of the substance of naturally impure objects changes the name which was given to it so that it is no more applicable to it and it is given a new name which is given to a pure object, so it is no more an impure thing. It becomes a new object, with a new rule.” … More IS GELATIN HARAM – WHAT IS ISTIHALA – CAN MY KIDS EAT JELLY CANDY – JELLY SNAKES – RUM FLAVOUR CANDY IS HALAL?
