白茶黄曲霉毒素检测数据
收藏资源简介:
对本公司生产的白茶进行抽样检测,检测项目黄曲霉毒素含量,黄曲霉毒素含量是其食品安全的重要指标,从而为白茶质量分析评价提供事实依据。数据采集,随机抽取白茶成品,对该成品进行黄曲霉毒素含量进行检测。数据判定:黄曲霉毒素实测值不大于20μg/kg,则该成品为合格,X=0.0004×(V1/V2)×D×(1000/m):X为试样中黄曲霉毒素的含量,μg/kg,V1为样液浓缩后体积,,mL,V2为出现最低荧光样液的滴加体积,mL,D为浓缩样液的总稀释倍数,m为浓缩样液中所相当的试样质量,g,0.0004为黄曲霉毒素的最低检出量,μg。
Sampling inspection was conducted on the white tea produced by our company, with aflatoxin content as the test item. Aflatoxin content is an important indicator of food safety, providing factual basis for the quality analysis and evaluation of white tea. Data collection: Finished white tea products were randomly selected for aflatoxin content testing. Data judgment: If the measured aflatoxin value is no more than 20 μg/kg, the finished product is considered qualified. The calculation formula is: X=0.0004×(V1/V2)×D×(1000/m) Where: X: aflatoxin content in the test sample, μg/kg V1: volume of the concentrated sample solution, mL V2: dropping volume of the sample solution exhibiting the minimum fluorescence, mL D: total dilution factor of the concentrated sample solution m: mass of the test sample corresponding to the concentrated sample solution, g 0.0004: minimum detectable amount of aflatoxin, μg
