Benzoic acid intake from drinks in Hong Kong students

What it found

Secondary school students in Hong Kong took in benzoic acid from pre-packaged drinks at levels below the acceptable daily intake.

Soft drinks were the main source.

What they found

Studies in people

Average exposure

Average consumers took in 0.31 mg per kg of body weight per day from pre-packaged drinks. This was 6.1% of the acceptable daily intake.

High exposure

High consumers, at the 95th percentile, took in 0.97 mg per kg of body weight per day. This was 19.3% of the acceptable daily intake.

Main drink source

Soft drinks contributed most to benzoic acid exposure from pre-packaged drinks, as in other countries.

What the authors conclude

  • They report that average and high consumers took in 6.1% and 19.3% of the acceptable daily intake, respectively.
  • They note that soft drinks contributed most to dietary exposure to benzoic acid from pre-packaged beverages in Hong Kong.

How it was done

The study estimated how much benzoic acid students in Hong Kong got from pre-packaged drinks. It used local food consumption data from 2000 and benzoic acid levels measured in drinks available locally in late 2006.

What it can’t tell you

  • We summarised it from the abstract only.
  • This study estimated exposure from drinks only, not from all foods.
  • It used consumption data from 2000 and drink levels from 2006, so it may not reflect current intakes.
