This document applies to Pingshan Huangqin protected by geographical indication certification trademarks. Main technical content: 1. Geographical environment: Mountainous areas with an altitude of 400m to 1500m. Calcareous brown soil, mainly with a sandy loam texture, with a pH range of 7.2 to 8.4. The average annual sunshine duration is 2288.6 hours, the average annual temperature is 12.4°C, the active temperature above 0°C is 4700°C, and the average annual rainfall is 550mm. 2. Quality requirements: 2.1 Sensory requirements: - Color: Brownish yellow or dark yellow on the surface. - Shape: Conical, twisted, with a length of 8–25cm and a diameter of 1–3cm. There are sparse wart-like fine root marks, twisted longitudinal wrinkles or irregular net patterns. The lower part has stubborn wrinkles and fine wrinkles. - Old roots have a dried or hollow center, dark brown or brownish black. - Cultivated products are relatively slender and often branched, with a light yellow-brown surface and a tightly adhering outer skin. The longitudinal wrinkles are finer. - Cross-section: Yellow or light yellow, slightly horn-like. - Odor: Weak, bitter. - Tissue state: Hard and brittle, easy to break, with a yellow cross-section and a red-brown center. 2.2 Physicochemical indicators: - Water content: % ≤ 12.0 - Total ash: % ≤ 6.0 - Alcohol-soluble extract: % ≥ 40.0 - Huangqin glycoside: % ≥ 8.0 2.3 Safety requirements: - Heavy metal limits: - Lead (as Pb): (mg/kg) ≤ 5.0 - Cadmium (as Cd): (mg/kg) ≤ 0.3 - Arsenic (as As): (mg/kg) ≤ 2.0 - Mercury (as Hg): (mg/kg) ≤ 0.2 - Copper (as Cu): (mg/kg) ≤ 20.0 - Pesticide residues shall comply with relevant
