Question

Why gelatin is generally added to ice cream?

Answer 1

Colloids:

• Colloids are the heterogeneous mixtures, in which the solute particles are of size $1\mathrm{nm}\mathrm{to}1000\mathrm{nm}$.
• Ice-cream is a colloid, which is stabilized using gelatin.

Gelatins:

• Gelatins are the food ingredients obtained from collagen.
• It is tasteless and colorless.
• When added to Ice-creams, it acts as an emulsifier (an additive which is used to mix two liquids). It gives the Ice-cream its texture and keeps it fresh.
• It also prevents the formation of large crystals in the ice creams.
