Introduction

Analysis of the Standard's Core Content

GH/T 1240-2019, for the first time, systematically defines the product grading, quality indicators, and testing methods for dried Cordyceps militaris. The standard categorizes products into three grades: special grade, first grade, and second grade. The core difference lies in the cordycepin content requirements: special grade ≥10,000 mg/kg, first grade 5,000-10,000 mg/kg, and second grade 1,000-5,000 mg/kg.

Comparison of key technical indicators

Test items	Special indicators	First-level indicators	Second-level indicators	Test methods
Cordycepin	≥10000mg/kg	5000-10000mg/kg	1000-5000mg/kg	NY/T 2116
Adenosine	≥550mg/kg			NY/T 2116
Moisture	≤12.0g/100g			GB 5009.3
Sulfur dioxide	≤0.05g/kg			GB 5009.34

Key points for standard implementation

Raw material control requirements

The standard clearly stipulates that the raw material must be fresh Cordyceps militaris fruiting body, and the mushroom body must be complete and yellow or orange in color. In actual production, it is recommended to establish a raw material acceptance system, focusing on the following checks:

Freshness: Processing within 24 hours of harvest
Microbiological control: Total mold count ≤10,000 CFU/g
Pesticide residue screening: Refer to the limits for 58 pesticides in GB 2763

Drying Process Optimization

To achieve the ≤12% moisture requirement, a gradient drying method is recommended: 40°C for initial drying for 2 hours → 55°C for main drying for 4 hours → 35°C for final drying for 2 hours. One company has demonstrated that this process can increase cordycepin retention by 15%.

Precautions for Detection Method

Special attention should be paid to cordycepin detection:

Use 50% methanol solution for ultrasonic extraction during sample pretreatment
Chromatographic conditions: C18 column, detection wavelength 260nm
The standard curve range should cover 100-12000mg/kg

Analysis of Standard Evolution

Compared with the 2009 version of the General Standard for Edible Fungi GB 7096, the innovations of this standard are:

Establishment of a dedicated quality grading system for Cordyceps militaris for the first time
Introduction of indicators for active ingredients such as cordycepin and adenosine
Tightening the limit for sulfur dioxide from 0.1g/kg to 0.05g/kg
