FIG. 4.

Discrimination (with respect to inoculants and time points) between the results seen with four fermentations of red clover juice. The results of cross-validated DFA using 15 PCs accounting for 99.97% total variance and a priori knowledge of the sample class structure, for which A (control), B (L. plantarum Lp01), C (L. lactis), and D (L. plantarum Lp02) represent the results seen after fermentation for 48 h (A1, B1, C1, and D1), 72 h (A2, B2, C2, and D2), and 96 h (A3, B3, C3, and D3); circles and lightface characters indicate training data, and stars and boldface characters indicate test data. The points shown represent the mean DFA scores calculated from three machine replicates taken for each sample.
