Which Lime Is Used in Fruit Juice Clarification?

Fruit juice clarification is an important step in making juices clear, clean, and impurity-free. When fruits are crushed, the juice contains pulp, pectin, acids, and suspended solids that make the juice cloudy. To remove these impurities, safe and approved clarifying agents are used — and food-grade lime is one of them.

The lime used in fruit juice clarification is Food-Grade Hydrated Lime (Calcium Hydroxide).
It is also called Food-Grade Slaked Lime or Khaane Wala Chuna (Food Grade).

This high-purity lime helps remove excess acidity, improves clarity, and reduces natural impurities in fruit juices like sugarcane juice, lemon juice, apple juice, grape juice, and citrus juices.

Why Lime Is Used in Fruit Juice Clarification.

  • Helps reduce acidity (pH adjustment)
  • Removes suspended impurities
  • Reacts with pectin and helps settle solids
  • Improves juice clarity and brightness
  • Helps in precipitating unwanted particles
  • Makes juice cleaner and more stable for processing
  • Safe for food when food-grade calcium hydroxide is used

How Lime Works in Juice Clarification.

When food-grade hydrated lime is added to fruit juice:

  • It reacts with acids in the juice.
  • Suspended solids, pectin, and impurities bind to the lime.
  • These impurities become heavier and settle at the bottom.
  • The clarified juice is separated from the settled material.

This makes the juice clean, bright, stable, and easier to filter.

Lime Type Scientific Name Food Safe? Used in Juice Clarification? Purpose
Food-Grade Hydrated Lime Calcium Hydroxide (Ca(OH)₂) ✔ Yes ✔ Yes Neutralization, pectin removal, impurity settling
Precipitated Calcium Carbonate (PCC) CaCO₃ ✔ Yes ✔ Limited Used in some clarification systems
