Application of Gelatin in Ice Cream

Gelatin is used in ice cream production as a stabilizer and texture enhancer, especially in traditional and artisanal formulations. It helps improve the smoothness, creaminess, and shelf life of ice cream by controlling ice crystal growth and maintaining a uniform structure.

1. Stabilizer

Gelatin helps prevent the formation of large ice crystals, ensuring a smooth and creamy texture.
It stabilizes the emulsion of fat, water, and air, reducing melting and dripping during storage and serving.

2. Texture Enhancer

Contributes to a rich, velvety mouthfeel, compensating for reduced fat or solids.
Useful in low-fat or reduced-calorie ice creams where richness is harder to achieve naturally.

3. Foam and Air Stabilizer

During churning, air is incorporated into the ice cream (overrun).
Gelatin stabilizes these air bubbles, ensuring even distribution and a light, scoopable consistency.

4. Shelf-Life Extender

Gelatin improves freeze-thaw stability, helping ice cream maintain its structure over time without becoming grainy or icy.
