IQF Frozen Shiitake Mushroom

The manufacturing process of IQF Frozen Shiitake Mushroom is precise and extensive, intending to preserve the flavor and nourishment of shiitake mushrooms to the greatest extent.

The very first step is to select raw materials. We pick high-quality shiitake mushrooms with thick and rounded caps, 4-6 centimeters in diameter, fine and neat folds, all-natural brown color, firm appearance, without insects and defects, to make certain moderate maturation and rich flavor.

After collecting, they are swiftly sent out to the workshop for cleaning. The mushroom bodies are carefully washed with a large quantity of running water to eliminate surface area mud, dust and recurring chemicals. If needed, the folds up are taken care of with a soft brush, and the water is drained after washing. Then the mushroom bodies are arranged and graded according to their shapes and size, and defective products are removed to make sure product consistency. Some processes consist of the action of eliminating eco-friendly, boiling the shiitake mushrooms in 98-100 ℃ warm water for 1-2 minutes to inactivate enzyme task, and afterwards cooling them with cold water to preserve a crisp and tender preference.

Then comes the important quick-freezing step. Using an IQF fluidized bed quick-freezer, the mushrooms are uniformly spread out on a conveyor belt in a low-temperature zone of -30 ℃ to -40 ℃. Solid wind flow causes the water to ice up into little ice crystals really quickly, which takes concerning 8-12 minutes, without damaging the cell framework.

Finally, they are vacuum-packed with high-barrier plastic film and immediately kept in a freezer listed below -18 ℃. The temperature and moisture are frequently kept track of to ensure secure quality within the 12-24 month life span.
