Dear all,
In the Dutch food composition database we need to include more and more 
brand data in order to cover the needs of our users. Both researchers and 
dietitians ask for details on mineral and vitamin content of these foods. 
Unfortunatelly this information is generally not available from the labels 
nor from the producers. We try to fill in these missing data as good as 
possible by borrowing from similar foods, estimations or calculations. 
Such calculations can be based on the ingredients as known from the 
labels. By trying several senario's we try to get the composition for the 
macronutrients as close as possible to the values on the label and use the 
micronutrients as calculated at the same time. 

This is a time consuming approach that gives an estimation of the 
composition, and it is the best we have at the moment. To work more 
efficient we are looking for way to find a more automated procedure. 
A literature search so far revealed the approach used for the NDSR 
database as desribed by Westrich (1994 and 1998) who developed sofware to 
calculate the composition of brand foods, based on the ingredients on the 
label. This software is at the moment not available to use with other e.g. 
European food composition databases. I did not find any more papers on 
this issue.

My question to you are: 
Are you aware of any other publications on this topic?
Are you aware of software that is available for this purpose?
Do you have specific experience with calculating composition based on the 
ingredients on labels (with or without using specific software)?
 
I suppose filling in missing values of brand foods by recipe calculations 
is done by other food database compilers as well. I would be glad to hear 
and learn from you. 
Thanks in advance,
with kind regards,
Susanne
