SO2 Champignon Mushroom in Drums
Product Introduction
SO2 Champignon Mushroom in Drums is produced from fresh white button mushrooms (Agaricus bisporus) that are carefully selected, cleaned, and preserved in a sulfur dioxide (SO2) solution. This preservation method helps prevent enzymatic browning and maintains the mushrooms’ natural white appearance during extended storage.
SO2 champignon mushroom in drums is designed as a semi-processed raw material for industrial use, particularly in mushroom canning, slicing, and further processing applications. It is not intended for direct consumption without appropriate treatment.
Drum packaging ensures efficient bulk handling, long-distance transportation, and stable storage conditions.
Raw Material Selection
Only fresh, firm, and closed-cap champignon mushrooms are selected. Mushrooms must be free from decay, excessive maturity, mechanical damage, or discoloration.
Proper harvesting stage ensures dense texture and optimal performance in downstream processing.
