236 SULFITES: ASSESSMENT OF DIETARY EXPOSURE
Table 5. Assessment of long-term dietary exposure to sulfites based on
individual dietary surveys
Country Type of survey
(year)
Brazil One 24-h
recall;
adolescents
aged 11–17
years; sample
size 140 (2002)
France 7-day diary
record; aged
3+ years;
sample size
used for the
exposure
assessment:
2492
(1998–1999)
Assumptions used for
the assessment of
dietary exposure
Assessment of
dietary exposure
only from fruit juice
Mean analytical data
in selected fruit juices
(containing sulfites
according to the label)
Adjusted for
individual body
weight
Corrections for
dilution according to
instructions from
manufacturers in
case of concentrates
Average use levels
(reported data from
food industry)
Adjusted for
individual body
weight
Two different
scenarios related to
the food habits: 1)
consumers randomly
consume foods that
do or do not contain
sulfites; 2) consumers
always consume
foods that contain
sulfites
