摘要
本研究利用iTongue20电子舌技术对4种不同生产批次(12月5—8日)及室温开封后不同贮藏时间(12、24 h)的纯牛奶进行风味分析和品质控制评估。通过线性判别分析(LDA)对电子舌采集的味觉信号数据进行处理,结果表明:电子舌能有效区分不同批次纯牛奶的滋味差异,且可准确识别合格品与室温放置24 h后的不合格品(欧氏距离达23.74)。此外,基于合格样品构建的品质模型验证了电子舌在快速检测中的可靠性,预测准确率达100%。本研究证实电子舌技术在牛奶品质控制中具有高效、客观和自动化优势,可为食品工业提供科学的质量管理方案。
This study utilized the iTongue20 electronic tongue technology to conduct flavor analysis and quality control evaluation on four different production batches(December 5-8)and pure milk with different storage times after opening at room temperature(12 and 24 hours).The taste signal data collected by the electronic tongue were processed using LinearDiscriminant Analysis(LDA).The results showed that the electronic tongue could effectively distinguish the taste differences between different batches of pure milk and accurately identify qualified products from unqualified ones after being stored at room temperature for 24 hours(Euclidean distance reached 23.74).Additionally,the quality model constructed based on qualified samples validated the reliability of the electronic tongue in rapid detection,achieving a prediction accuracy of 100%.This study confirmed that the electronic tongue technology has efficient,objective,and automated advantages in milk quality control,providing a scientific quality management solution for the food industry.
