Execution standards for dehydrated ginger chunks

Core Execution Standards

Industry standard: NY/T 1073-2006 "Dehydrated Ginger Slices and Ginger Powder" is currently the only specialized agricultural industry standard in China for dehydrated ginger chunks (including ginger slices and ginger powder), applicable to products made from Zingiber officinale Roscoe, a plant in the ginger family, through cleaning, slicing, dehydration and drying.

Content covered: technical requirements, testing methods, inspection rules, labeling, packaging, transportation, and storage.

Key indicators:

Moisture content: ≤ 12%

Total ash content: ≤ 6.0%

Acid insoluble ash content: ≤ 1.0%

Impurities: ≤ 1.0%

Microbial limit: Complies with GB 4789 series standards (total bacterial count ≤ 10 ⁴ CFU/g, coliform group ≤ 10 MPN/g, no Salmonella, Shigella, Staphylococcus aureus detected)

Mandatory food safety standards

Dehydrated ginger chunks as food must meet the following mandatory national standards simultaneously:

|Standard number | Standard name | Key limit requirements|

|GB 2762-2022 | Limits of Pollutants in Food | Lead ≤ 0.5 mg/kg, Arsenic ≤ 0.5 mg/kg, Cadmium ≤ 0.1 mg/kg, Mercury ≤ 0.02 mg/kg|

|GB 2763-2024 | Maximum residue limits for pesticides in food | Thiamethoxam ≤ 0.5 mg/kg, Chlorpyrifos ≤ 0.1 mg/kg, Carbendazim ≤ 0.5 mg/kg|

|GB 4789.1-2022 | General Principles for Microbiological Examination of Food | The production process must comply with GB 14881 "General Hygiene Standards for Food Production"|

|GB 5009.3-2022 | Determination of moisture in food | As a legal method for moisture detection|

|GB 7718-2022 | General rules for pre packaged food labeling | Must indicate: product name, ingredients, net content, production date, shelf life, production license number (SC), and implementation standard number|

Note: Although sulfur dioxide residue is not specified in NY/T 1073, if sulfur fumigation drying process is used, it must comply with the maximum residue limit of ≤ 100 mg/kg for "dried vegetables" in GB 2760.

Local and group standards

T/SDYY 256-2026 "Technical Regulations for Processing Dehydrated Ginger Slices" (Group Standard of Shandong Province)

For the main ginger producing areas in Shandong (such as Linyi and Laiwu), we have formulated and refined:

Raw material acceptance criteria (fresh ginger without decay, no pesticide residue)

Process control (hot air drying temperature ≤ 70 ℃ to avoid loss of active ingredients)

Packaging material requirements (food grade PE or composite film, in accordance with GB 4806.7)

Labeling standards (must indicate "dehydrated ginger slices" or "dehydrated ginger chunks", must not indicate "dried ginger" to avoid confusion with medicinal use)

Scope of application: Production enterprises within Shandong Province, as a local regulatory basis, have technical requirements stricter than national standards.

International standard reference

ISO 1003:2025 "Spices and conditions - Whole/pieces and ground flowing ginger"

International standard, highly compatible with Chinese standards, suitable for export products.

Core requirements:

Sensory: No mold, no odor, uniform color (light yellow to brownish yellow)

Physical and chemical properties: moisture content ≤ 12%, ash content ≤ 6.0%, foreign matter ≤ 1.0%

Hygiene: No pathogenic bacteria shall be detected, and the total number of molds shall be ≤ 10 ³ CFU/g

Packaging: Moisture proof, light proof, sealed, with labels indicating country of origin, batch number, and storage conditions

Chinese GB/T 30383 "Ginger" is equivalent to ISO 1003, providing basic support for the raw material source of dehydrated ginger chunks.

Classification of medicinal standards

The "Dried Ginger" item in the 2020 edition of the Chinese Pharmacopoeia:

Suitable for traditional Chinese medicine, not suitable for food grade dehydrated ginger chunks.

Moisture content ≤ 19.0%, volatile oil ≥ 0.8% (ml/g), total ash content ≤ 6.0%.

If the product is used for decoction pieces of traditional Chinese medicine or Tonic Diet, it shall be executed according to the pharmacopoeia and marked with the word "medicinal".

Enterprise Standards and Compliance Tips

Enterprises may establish Q/XXX enterprise standards that are stricter than national standards, but must:

Filing with the local health commission

Not lower than mandatory requirements such as NY/T 1073, GB 2762, GB 2763, etc

Typical filing example: Q/LHY 0001 S-2011 "Dehydrated Ginger Slices (Blocks)" (Shandong Enterprise)

Add "gingerol content ≥ 1.5%" as a quality control indicator to enhance product added value.

Testing and compliance recommendations

Factory inspection items: moisture, ash content, microorganisms, pesticide residues (sampled by batch)

Third party testing institutions: Laboratories with CMA/CNAS qualifications (such as Zhongke Testing and Puni Testing) can provide comprehensive testing services

Enterprises in Linyi, Shandong Province: It is recommended to prioritize the use of T/SDYY 256-2026 to enhance regional brand recognition
