The purpose is classification of stress tolerances of spoilage bacteria using Raman spectra and chemometrics. We obtained Raman spectra of six spoilage bacteria. Classification models were constructed with support vector machine and classified food-related stress tolerance with 90% accuracy, which provides bacterial characteristics specific to environment reducing food spoilage.
目的是使用拉曼光谱和化学计量学对腐败菌的应激耐受性进行分类。我们得到了六种腐败菌的拉曼光谱。使用支持向量机构建了分类模型，其对与食品相关的应激耐受性的分类准确率达到了 90%，这为减少食品腐败提供了具有环境特异性的细菌特征。
