Buyer FAQ – Whole Mushroom in SO₂ (Plastic Drums)

1. What type of buyer is whole mushroom in SO2 designed for?

This product is intended for industrial users such as canneries, frozen food factories, ingredient processors, and large-scale food manufacturers. It is not meant for direct retail sale without further processing.


2. Why is SO₂ used instead of only salt or acid?

SO₂ provides strong enzymatic browning control and color stabilization, especially for long storage and long-distance transport.

Compared with salt-only systems, SO₂ helps maintain a lighter mushroom color and more uniform appearance during extended holding periods.


3. Can the SO₂ level of Whole mushroom in SO2 be customized for different markets?

Yes. Total and free SO₂ levels can be adjusted to comply with specific importing country regulations (EU, US, Middle East, Asia, etc.). Target ranges are agreed before production and verified by COA.


4. Will SO₂ affect taste after processing?

When mushrooms are properly rinsed and thermally processed, residual SO₂ is significantly reduced and does not affect final flavor. Most industrial buyers report a neutral taste profile in the finished product.


5. Are the mushrooms fully cooked or raw?

They are raw, preserved mushrooms. Cooking or blanching must be carried out by the buyer during further processing.


6. What size of whole mushroom in SO2 options are available?

Common options include small, medium, and mixed sizes. Custom size grading can be arranged depending on end-use requirements such as whole-can packing or slicing efficiency.


7. How long can unopened drums be stored?

Unopened plastic drums can typically be stored for up to 24 months under recommended conditions (cool, dry, shaded storage).


8. Is rinsing required before use?

Yes. Buyers should rinse or soak the mushrooms before processing to reduce residual SO₂ and adjust the product to their specific formulation needs.
