Lightness, yellowness andredness as color parameters of the DL samples were evaluated. Carbohydrate profile and contents in DLsamples were also determined by HPLC. The data were treated using Principal Component Analysis (PCA).Extensive variability among all the parameters evaluated was observed, as a result of using different DLproduction procedures in the dairies. In this regard, PCA was shown to be useful to separate the DL sampleswith distinct physicochemical characteristics and to assess the influence of different production techniqueson the properties of DL samples.eninfo:eu-repo/semantics/openAccessGıda Bilimi ve TeknolojisiArticle4361091109910.15237/gida.GD18111393228
