Introduction

Interpretation of the core content of the standard

This standard applies to the dried flower buds of three species of Magnoliaceae, namely Magnolia grandiflora, Magnolia dahurica and Magnolia wudangensis, and specifies sensory indicators such as external dimensions (1.2-4cm), color (grayish white to light grayish white) and odor characteristics (rich and fresh).

Comparison of key technical indicators

Test items	Indicator limit	Test method	Commercial significance
Volatile oil content	≥1.5mL/100g	GB/T 30385	Key indicator for determining aroma quality
Acid insoluble ash	≤1.0%	ISO 930	Reflects the content of impurities such as sediment
Crude fiber	≤20.5%	ISO 5498	Important parameters affecting taste

Key points for standard implementation

Raw material control requirements

Explicitly require that stem ingredients should not be contained, the total amount of foreign matter should be controlled within 2%, and the magnification of insect pest detection should be indicated (recorded when >10 times).

Selection of detection methods

The moisture determination adopts the ISO 939 azeotropic method, which can more accurately determine the content of volatile components compared with the conventional drying method.

Storage and transportation specifications

Emphasis on the requirements for ventilation and moisture-proof warehouses, stacking must retain a ventilation channel of more than 30cm, and transportation vehicles must be specially cleaned.

Standard Evolution Analysis

This version of the standard includes Wudang Magnolia as a raw material for the first time, and the volatile oil index is increased by 0.3mL/100g compared with the 2008 version, reflecting the industry's improved requirements for aroma quality. The testing methods are fully aligned with international standards (ISO series).
