Gummy Sweets and the Science of their Chewiness

Time : 2024-04-22

Many people love gummy sweets because they are sweets with unique texture, chewy, and tasty. But why are they so chewy? This is what we want to investigate here.

Role Played by Gelatin

The main component responsible for toughness in gummy sweets is gelatin. Gelatin is a protein obtained from collagen, another natural protein found in animal connective tissues. When gelatin combines with water and gets heated it forms a semi-solid jelly-like substance that constitutes the major part of gummy sweets.

Gelation Process

Gelation causes the chewing effect on gummy sweets. During heating of the mixture of water and gelatin, gelatins proteins straighten into single threads. As the solution cools down these protein strands recombine into another configuration which networks trapping water molecules to form semi-rigid yet elastic material known as gummi candies.

Sugar Effects

Chewiness in gummy sweets relies heavily on sugar content. High concentration sugars tighten the network formed by gelatine hence increases stiffness of gummi candies.Additionally sugar acts as a preservative inhibiting microbial growth thus extending shelf life.

Other Influences on Chewiness

There are other factors that affect how chewy gummies are. For instance citric acid or any acid can be added to lower pH making jalaten more likely to set resulting in firmer texture. On the contrary adding fatty materials would disrupt the gelatine network yielding soft candy treats.


The gummy sweets that characterized gummies is an exciting marriage between ingredients and science.This knowledge can help us better enjoy these delicious confections and also allow us to create new confectionery flavors or textures too.
