Best Commercial Method for Egg Preservation
An excellent method for commercial preservation of eggs is:
- Cold storage method — Correct Answer
- Thermo-stabilization
- Pasteurization
- Water glass method
Explanation:
Correct Answer: Cold storage method
The cold storage method is the most excellent and widely used method for commercial preservation of large numbers of eggs.
Cold Storage Method Details
- Temperature: 14°C with 90% Relative Humidity.
- Oil-coated eggs: Can be preserved for up to 8 months.
- Non-oil-coated eggs: Can be preserved for up to 6 months.
- Oil coating seals the shell pores, preventing moisture loss and microbial entry.
All Methods of Egg Preservation
| Method | Scale | Duration |
|---|---|---|
| Lime water (CaOH₂) | Home | 1 month (room temp) |
| Water glass (Na silicate) | Home | 1 month (room temp) |
| Oil coating | Home/Commercial | Extends shelf life |
| Cold storage | Commercial | 6–8 months at 14°C |
| Thermo-stabilization | Commercial | Stabilizes albumin quality |
| Pasteurization | Commercial (liquid egg) | — |
Why Other Options Are Wrong
- Thermo-stabilization → excellent for albumin quality but not the primary commercial preservation method for whole eggs.
- Pasteurization → used for liquid/broken-out eggs, not whole shell eggs.
- Water glass → a home-scale preservation method only.
