Slice Thickness Control
We prepare sliced shiitake mushrooms by confirmed thickness, cap diameter and stem requirement. For retail and foodservice programs, we can discuss lower broken slice tolerance and more uniform visual appearance.
Cleaning and Free-Flowing Condition
We inspect substrate residue, sand, foreign matter, clumping and broken slices before packing. Bulk, foodservice, retail and private label packing can be matched to the order plan.
Blanched / Unblanched Option
For sliced shiitake mushrooms, we can discuss blanched or unblanched processing according to application. Blanched slices are useful for soup, ready meals and foodservice programs where color stability is important. Unblanched slices are selected for applications that need stronger natural shiitake aroma and firmer texture.
