Different letters in same attribute axis indicates significant differences between
storage times (p < 0.05)
Before tasting the three samples, the panelists evaluated the fermented
hazelnut milk as having a very good appearance with the exception of the
sample stored for 28 days (p < 0.05). As these samples were presented in
transparent glasses, the panelists were able to notice the sample syneresis
and serum separation at the bottom; this separation was negatively
evaluated.
