We have some powdered colors that were purchased prior to our facility becoming SQF certified, and as such the prior person's in charge of the COAs did not keep the best of records. The issue is that now the colors are technically "expired" and I know that the manufacturers aren't going to grant extensions to some of these colors which are 10+ years old.
What steps would you personally take to grant extensions to these colors? Throwing them out is not an option at the moment.
I could check for moisture and salmonella, I suppose? Any thoughts would be appreciated.
