Acrylamide Dynamic concept of minimisation
data collection

• signal value

success
signal value exceedance
minimisation dialogue
minimisation measure

Signal values, 4th calculation

• assessment period 01 Sep 2003 31 Aug 2004
• data sets 1792
• Modification of the minimisation concept
• Evaluation of the success of the concept so far
  by
• Signal value
• Median
• Frequency distribution
• further, new evaluation of the success of the
  concept by
• Observation value

Evaluation

• Signal value
• Defined calculation
• - Limiting conditions
• max. 1000 µg/kg
• once calculated no raising
• - Exceedence start of minimisation dialogue,
  minimisation measures
• Evaluation of success of minimisation efforts,
  within the framework of conditions defined for
  the signal value
• Observation value
• - Calculation basically in the same way as the
  signal value
• - but no limiting conditions like for the signal
  value
• Evaluation of success of minimisation efforts,
  even when the signal value is unchanged
• Frequency distribution, e. g. shift to the left

5
Signal values, 4th calculation

• Assessment of the development of signal values 4
  categories
• Signal value decreased
• 2 product groups
• Signal value unchanged
• 1 product group
• Signal value unchanged (and observation value
  decreased)
• 5 product groups
• Signal value unchanged (and observation value
  increased)
• 5 product groups
