This is an agency report, not a journal article. Table 2 prints pancake aluminum as mean 55 (ND to 490) mg/kg, n = 9, as purchased, rounded to 2 significant figures. The mean uses one half of the limit of detection for non-detects. The limit of detection is 0.5 mg/kg and the limit of quantification is 2 mg/kg. Waffle is a separate row (mean 270 mg/kg) and is not used. The pancake-mix pool (n = 5, mean 290 mg/kg, range 0.59 to 1100 mg/kg) is not assigned to pancakes.
Key numbers
Pancake, n = 9, mean 55 mg/kg, range ND to 490 mg/kg. Aluminum only.
Methods (brief)
Market foods in Hong Kong, 2015. Aluminum reported as purchased. Non-detects in the mean use half the detection limit.
Evidence fitness
The pancake row supports an agency-survey aluminum note for pancakes. It does not support waffles or pancake mix as pancakes.
Limitations
The mean includes a half-detection-limit substitution for non-detects. The range includes ND. No certified reference material result is printed in the pancake section.
