By observing the results obtained from these two studies it can be seen that the rate of fat bloom development at the surface, the roughness development and the oil migration rate is significantly higher for the samples containing 68 wt% non-fat particles compared to the samples containing 25 wt% non-fat particles.
After 12 weeks storage at 23 _C the relative Rq values are a factor 2–3 times higher for the samples including 68 wt% particles compared to the samples including 25 wt% particles, and after 6 weeks storage the mean concentration of BrTAGs in the shell fat matrix is approximately three times higher for the samples containing 68 wt% particles than for the samples including 25 wt% particles.
