2.7. Analysis of meat drippings
Meat drippings obtained from both beef loin and pork belly
were collected in a beaker placed in an ice bucket during grilling
(Fig. 1). Meats were repeatedly grilled until the amount of dripping
was over 25 mL. The pooled drippings were analysed for moisture
by air oven drying (AOAC Method 950.46) and for fat by the Rose-
Gottlieb method (AOAC Method 905.02; AOAC, 2000, chaps. 33 and
39). The experiment was repeated 3 times. The amount of others
was estimated by the ‘difference method’, i.e. calculated as the
residue after accounting for moisture and fat.
2.8. Statistical analysis
All results are calculated as means and standard deviations.
Assessment of significant differences in PAH contents between
the different procedures was conducted by using the student’s ttest
(Microsoft Office Excel 2007; Microsoft Corporation, Seattle,
WA).
