基于紫外指纹图谱技术的食醋品种检测方法（Method of Vinegar Detection Based on Ultraviolet Fingerprint Technology）
食醋 检测 紫外光谱
2009/5/22
以不同食醋为研究对象，采用旋转蒸发、紫外光谱扫描等手段研究了波长范围、蒸发液稀释比例、蒸发温度和参比液质量浓度等对食醋紫外吸收曲线的影响，确定了食醋紫外指纹图谱检测方法的试验条件：扫描波长范围245～330nm，蒸发液稀释比例1∶6，蒸发温度45℃，冰醋酸参比液质量浓度45g/L。以曲线间的相似度为指标验证了方法的重现性、稳定性和差异性，结果表明：各个食醋样品3次重复测定的指纹图谱间相似度均大于0...
