Champignon mushrooms in SO2 are freshly harvested white button mushrooms that are lightly preserved in a controlled sulfur dioxide solution to maintain their natural color, firmness, and aroma during long-distance transportation and industrial processing.
Champignon mushrooms in SO2 is widely used by canneries, food processors, and manufacturers requiring high-quality raw materials for further production.
Fresh Raw Material
Selected A-grade champignon mushrooms, picked at peak maturity to ensure uniform color, texture, and size.
SO2 Preservation for Stability
Packed in food-grade drums with an optimized concentration of sulfur dioxide solution, effectively preventing browning and microbial growth.
Long Shelf Life
Suitable for storage and transport over long periods without loss of quality.
Ideal for Processing
Perfect for further manufacturing such as canned mushrooms, marinated mushrooms, pickled mushrooms, frozen mushroom products, and ready-to-eat mushroom dishes.

12–18 months, depending on SO₂ concentration and storage conditions.

1) Canning Industry
Champignon mushrooms in SO2 are used for producing canned whole mushrooms, canned sliced mushrooms, and mushroom pieces & stems.
SO₂ treatment ensures mushrooms keep their color during canning.
2) Pickled / Marinated Mushroom Processing
Champignon mushrooms in SO2 are the ideal raw material for pickled mushrooms, oil-marinated mushrooms, Mediterranean style mushrooms, and antipasti mixes.
3) Frozen Mushroom Production
Mushrooms can be washed, reprocessed, then frozen (IQF sliced, whole, or diced).
SO₂ ensures the mushrooms remain white even after thawing.
4) Food Ingredient Manufacturers
Used for soups, sauces, ready-meals, instant noodles topping, and retort foods.
Ensures stable texture and color in final dishes.
5) HoReCa / Catering Pre-Processing
For central kitchens that produce mushroom blends, pizza toppings, and hot-pot ingredients.
1) Excellent Color Retention
SO₂ effectively prevents enzymatic browning, keeping mushrooms bright white.
2) Long Storage Time
Suitable for long-distance shipping and long-term storage (several months).
3) High Raw Material Stability
Mushrooms remain firm and maintain their natural shape throughout processing.
4) Flexible for Further Processing
Can be produced into many end-products (canned, marinated, frozen, dehydrated).
5) Cost-Effective
Lower cost than fresh mushrooms; no spoilage during transport.
6) Wide Range of Sizes & Grades
Whole, sliced, quartered; small to large size available.

Q1: Are these Champignon mushrooms in SO2 edible directly from drums?
A: No. They must be thoroughly washed to remove SO₂ before final processing.
Q2: What SO₂ level remains after washing?
A: After standard washing/blanching, residual SO₂ becomes very low and compliant with food regulations.
Q3: Why choose Champignon mushrooms in SO2 instead of fresh?
A: SO₂ mushrooms maintain color, firmness, and are easier to store and ship over long distances.
Q4: What grade options are available for Champignon mushrooms in SO2?
A: Whole, sliced, quartered; small/medium/large; A/B/C grades.
Q5: How are the Champignon mushrooms in SO2 processed before packing?
A: Fresh mushrooms → sorting → trimming → washing → cutting (if needed) → SO₂ soaking → packed into drums.
Q6: Can the SO₂ concentration be adjusted?
A: Yes, we can adjust between 300–900 ppm based on customer requirements.
Q7: What is the main market for Champignon mushrooms in SO2?
A: Europe, Latin America, Middle East, Russia, Southeast Asia, and food processing factories worldwide.
