Best Commercial Method for Egg Preservation

An excellent method for commercial preservation of eggs is:

Options

Cold storage method ✓
Thermo-stabilization
Pasteurization
Water glass method

Correct Answer: A

Explanation in English

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.
