This is obviously not a new product and if you have been producing it for
other sources, there should be a supply on their shelves of different
production lots that you could test for shelf-life. Granted that this is
not a controlled test, but it will give you the rapid results that your new
client wants.

Subject: Re: Shelf life testing
Having done many accelerated shelf-life tests in my earlier days, there is
one mandatory guideline: you cannot correalate an accelerated test unless
you have the data from previous tests for comparison. I have heard many
"Marketing Guru's" ask, "Can't you tell me in a couple of weeks if this
brand new product will have a 12-month shelf life?" The answer is, "No!"
And remember, each new formula may need to be tested on its own.
You can accelerate the test by storing at elevated temperatures, but you
must also have data that says that the elevated temperature must not be so
high that it causes product degredation that would not occur in an extended
shelf life--such as undue carmellization, excess "cooking", etc. The best
way is to do the extended tests first at various holding temperatures, and
then have data for comparison. I'm sorry that this doesn't help, but that
is my opinion.
