NY/T 713-2003

This standard is primarily used by vanilla growers, processors, quality inspection agencies, and research institutions. They use it to accurately determine the vanillin content in vanilla beans and their processed products. It matters because it provides a unified testing method, ensuring quality control and fairness in trade.

这个标准主要被香草兰种植和加工企业、质检机构以及科研单位使用。他们用这个标准来准确测定香草兰豆荚及其加工产品中香兰素的含量。这个标准很重要，因为它提供了统一的检测方法，确保了产品质量控制和贸易中的公平性。

NY/T 713-2003 specifies three methods for determining vanillin in vanilla beans: high performance liquid chromatography (arbitration method), ultraviolet spectrophotometry, and gas chromatography. It applies to vanilla beans, cuts, and powder, but not extracts. HPLC uses acetylsalicylic acid as internal standard, UV spectrophotometry is based on ethanol extraction and specific absorbance calculation, and GC uses eugenol as internal standard. The standard modifies ISO 5562-2:1999 with technical adjustments for national conditions, adding the gas chromatography method.

NY/T 713-2003标准规定了香草兰豆荚中香兰素的三种测定方法：高效液相色谱法（仲裁法）、紫外分光光度法和气相色谱法。标准适用于香草兰豆荚、切段和粉末，但不适用于抽提物。高效液相色谱法使用内标物乙酰水杨酸，紫外分光光度法基于乙醇抽提和比吸光度计算，气相色谱法使用丁香酚内标。标准修改采用ISO 5562-2:1999，并根据国情进行了技术调整，增加了气相色谱法。
