T/CCAA 65-2023 Determination of β-Nicotinamide Mononucleotide (NMN) Content in Food by High-Performance Liquid Chromatography (HPLC)
Basic Information
Scope
Scope: This document specifies a high-performance liquid chromatography method for determining the content of β-nicotinamide mononucleotide (NMN) in food. This document is applicable to the determination of NMN content in NMN raw materials and NMN-containing capsules and tablets used in cross-border products. Main technical content: 1. Scope: This document specifies a high-performance liquid chromatography method for determining the content of β-nicotinamide mononucleotide (NMN) in food. This document is applicable to the determination of NMN content in NMN raw materials and NMN-containing capsules and tablets used in cross-border products. 2. Normative reference documents: The content of the following documents is an integral part of this document through normative references. Among them, the referenced documents with a specified date are only applicable to the version corresponding to that date; for the unspecified date referenced documents, the latest version (including all amendments) is applicable to this document. GB/T 6682: Specifications and test methods for water used in analytical laboratories. 3. Terms and definitions: This document does not define any terms or definitions. 4. Principle: The sample is dissolved in a 50% methanol aqueous solution, extracted by ultrasound, then centrifuged to remove impurities and filtered through a microporous membrane. The separation is performed by hydrophilic chromatography, and the detection is carried out by an ultraviolet detector using an external standard method for quantification. 5.
