On the other hand, it appears that the concentration of BrTAGs for the 22 and 40 lm samples goes through a maximum after 6 weeks of storage, still, the decrease in BrTAG concentration after 6 weeks of storage is not statistically significant. .
From these results it can be seen that at 500 lm from the filling there is no significant difference between the samples stored at 20 _C. At 1100 lm a slightly higher BrTAG concentration can be observed for the 15 lm samples after 15 weeks storage at 20 _C.
