“…Furthermore, the principal component analysis (PCA) was employed to investigate relationships among samples. The input matrix used for HCA and PCA consisted of the total area under growth/decline curves of LAB, yeasts, enterobacteria, pseudomonads, staphylococci, CPS as well as pH values (BautistaGallego et al, 2011;Blana, Grounta, Tassou, Nychas, & Panagou, 2014). Areas were calculated by integration using the OriginPro 7.5 sofware (OriginLab Corporation, Northampton, USA).…”
