I was wondering if others who create and maintain the nutrition facts panels for retail sale products could give me some input on what they do in this regard. With some of our packaging we incur additional costs to make changes so we try not to change the packaging if possible.
I am wondering if you have a set % difference in your nutrition facts panel where you decide that it must be changed to reflect new values? For instance if we change our product formula or ingredients (but the ingredient statement remains the same) and the new calculated or analyzed information is different- at what point do you decide that the change must be made? I know the FDA rules with compliance of nutritional data such as for Calories, Fat, Sodium- they should not exceed 20% of the declared value while those nutrients that individual's are typically trying to increase their intake of must be at least 80% of the stated value. We have very few products with class 1 nutrients (fortified). I have had these values in mind as cut off points for when the nutrition facts panel needs updated.
However, I am wondering what information I should view as necessary in deciding to make changes to the panel. I use Genesis R& D software and occasionally send off for 3rd party testing for certain nutrients. I typically receive nutrition information from suppliers- more often than not it is calculated and not analyzed info. I have caught several big errors with this supplied calculated info- they left off a 0 or put the decimal in the wrong place...
In addition, I have had issues with the lab analysis results: the lab we use has a variance of +/- 6% in the reported values. On some things that we aim to keep low, like sodium, can be quite affected by that 6% deviation. Another factor to take into consideration if I only sent in one sample for analysis is variance from lot to lot and that in the end the calculated information may be more reliable.
I have been finding inconsistencies between supplier calculated information and the results from the lab.
I guess I am wondering what information I should rely on and where I need to make guidelines that a change on the panel is necessary?
If I have calculated information but also have analyzed information would the analyzed information trump using the calculated? I feel obligated to use the higher values for a nutrient like sodium- but is that necessary?
I would really appreciate any guidance from others who have dealt with this!
