The shape of jelly is related to the size, shape and cooling time of the mold. Generally speaking, jelly does not need large or complicated moulds for its formation. Because the gel force inside the jelly is not enough to maintain the support force of the finished product made by large molds, if the use of raw materials is increased, the quality and taste of the finished product will inevitably be reduced, or even cannot be eaten.

Jelly is a kind of jelly food, which is mainly made of water, sugar or starch sugar, supplemented by food additives such as thickeners, with or without raw materials such as fruit and vegetable products, milk and dairy products, and processed through the processes of sol, blending, filling, sterilization, cooling, etc.
