Outline
Nutrient reference materials serve as fundamental substances for the determination and quality control of food nutritional components. They are essential tools for ensuring the scientific validity and regulatory compliance of food nutrition labeling, as well as advancing precision nutrition research. This paper systematically reviewed the development progress of nutrient reference materials both China and internationally. Existing studies indicate that China has established the world’s largest repository of nutrient reference materials, currently comprising more than 700 reference materials that cover major nutrient components such as proteins, lipids, carbohydrates, vitamins and elements. This had gradually formed a comprehensive system spanning from high purity reference materials to complex food-matrix reference materials. However, compared with internationally advanced standard, China still faced shortcomings in the balance of nutrient categories and diversity of matrix distributions, the development of reference materials with multi-nutrient characteristic quantities, and the characterization of structurally complex nutrients. Based on global trends in nutrition and health research and the urgent need for metrological support within China’s nutrition and health industry, this review aimed to provide theoretical guidance and practical insights for building a more comprehensive, scientifically robust and internationally influential nutrient reference material system.
