Whole, pieces and ground ginger are separate styles
CXS 343-2021 defines dried or dehydrated ginger from Zingiber officinale Roscoe rhizomes and recognizes whole rhizomes, pieces including cut, diced or sliced material, and ground or powdered product. Whole and pieces retain visible rhizome and defect evidence; grinding removes much of that visual identity and changes analytical and adulteration risk. Atlas keeps style, treatment and processing history explicit before comparing quality, crop, price or trade records.
