Fig. 1. Principal component analysis of low fat UHT milk in HDPE bottles stored at different temperatures for different numbers of days (D1-D192 for milk stored at 25 C, D1-D176 for milk stored at 35 C and D1-D78 for milk stored at 45 C) as profiled by the trained sensory panel: i), scores for the sensory attributes; ii), the correlation loadings for the milk samples stored at different temperatures over time
