T/GXDSL 401-2025 Standard for Quality Grading of Selenium-Enriched Agricultural Products
Basic Information
Scope
They are grown naturally in soil environments rich in selenium, or through the application of selenium fertilizers or selenium nutritional agents registered by the state and other bio-enhancement technologies during the growth of crops. This ensures that the total selenium content in their edible parts steadily reaches the secondary and higher content thresholds specified for corresponding product categories in Table 1 of Chapter 5 of this standard. At the same time, their safety indicators such as the limits of harmful pollutants and pesticide residues all comply with national mandatory standards, and they possess the inherent quality characteristics of the primary agricultural products and their initial processed products. Their core feature is that, under the premise of safety, they have relatively high natural selenium content that is beneficial to human health.
