The high R2 levels show high level of accuracy in
the obtained results.
According to Fig. 4 the butyric acid concentrations
in the tested yogurt samples during storage at
different time intervals showed that the probiotic
yogurt sample (211) had a reduction of approximately
0.16 % on first day of storage. The reduction slightly
continued till day two, but later the level increased
on day 10 reaching to the same levels as was on day
two (0.17%).
The results of ABY1 samples were more
significant and C4 levels in these samples were
approximately 0.2% on first day which decreased
significantly on day two (0.06%) and reached to
0.02% on day tenth. However, on day twentieth an
increase of approximately 0.06% in the butyric acid
concentrations was observed in this yogurt sample.
Although the ordinary yogurt samples also showed
levels of butyric acid concentrations till day twentieth
