the best way to increase the shelf life of mushrooms is MAP packaging, by increasing the Carbon dioxide and reduce the oxygen ratios in package can extend the shelf life of mashrooms

Dear friend,

I think Ways you can use to increase shelf life of mushrooms:

1-chilling the mushrooms from harvest to cooking

2- Using of antimicrobial agent (for example ozonized water, chlorine, chlorine dioxide, citric acid etc.)

3- Using anti browning agent (for example citric acid or other poly-hydroxyl acids, reducing agent(ascorbic acid) or chelating agent).

4-Using MAP (Modify Atmosphere packaging) or EMAP (Equilibrium Modify Atmosphere packaging).

5- Using new technologies such as irradiation or High Pressure Processing (HPP).

Try Modified Atmosphere Packaging, it works very well.

Try map

In my opinion, the simplest method is using the PVE thin film to package in sealed

Canning is a good technique for that purpose.
