However, the 15 lm samples stored at 23 _C show a higher concentration of BrTAGs in the shell fat matrix at a distance of 500 lm from the filling compared to the other samples over the whole storage period.
Further, at 6 weeks storage a maximum in BrTAG concentration can be observed for all samples. At 1100 lm from the filling-shell interface the 15 lm samples show the highest mean concentration of BrTAGs after 15 weeks storage at 23 _C, while the 22 and 40 lm samples stay at the same level as at 6 weeks storage.
