So I kind of need a little help in this matter as I haven't been in this position before. I need to establish specifications (micro, physical & chemicals) for spices & seasonings and I am little lost in how to start or where to start. A little brief overview, we repackage spices, herbs (single product that only gets repackaged into our packaging) and seasonings (we mix here and package). So I was thinking that for the single products that dont get mixed, I would have already had the spec sheet directly from the supplier. and for the seasoning that would be mixed at our facility, I would need to assess. How will this be established? Shall I send some samples of those products to a lab in multiples and establish the limits (specs)? Or is there a standard set (USA) for those specs? I tried looking up some guidance but couldn't find anything. Any help would be appreciated!
