Dehydrated Ginger Slices/Dices/Powderとは？用途・使用量・代替品・規格

Dehydrated Ginger is a processed product made from the fresh rhizomes of Zingiber officinale Roscoe (Zingiberaceae family) through cleaning, slicing, blanching, and dehydration processes such as hot air drying or vacuum freeze drying. The main forms include Dehydrated Ginger Slices and Dehydrated Ginger Powder. Dehydrated ginger has a moisture content reduced to 11%–13% and a water activity reduced to below 0.7, effectively inhibiting microbial growth and enabling long-term preservation. In China, dehydrated ginger is produced using advanced steam or hot air drying technology without any added preservatives or artificial colors, retaining the natural pungent flavor and health attributes of fresh ginger. Products are mainly exported to Japan, Europe, and the United States. Dehydrated ginger is a typical "Medicinal and Edible" substance, possessing dual attributes as both a seasoning and a functional food ingredient. Against the backdrop of the deepening "Medicinal and Edible" concept, ginger is gradually transforming from a single agricultural product into a composite raw material with both food and functional attributes, a transformation that serves as an important foundation for the continued expansion of its downstream applications.

Dehydrated ginger retains and concentrates various active components and functional properties of fresh ginger. Its core active components include gingerols (primarily 6-gingerol, 8-gingerol, and 10-gingerol), shogaols, and volatile oils (zingiberene, zingiberol, etc.). In terms of nutritional value, dehydrated ginger is rich in curcumin, vitamin C, zinc, potassium, and other trace elements. Key Functional Characteristics:

Antioxidant Activity: Gingerols and curcuminoids in ginger possess potent free radical scavenging capabilities. Dehydrated organic ginger is rich in curcumin, vitamin C, zinc, potassium, and other trace elements, contributing to antioxidant, anti-inflammatory, and digestive health benefits.
