Good morning everyone,
We have a customer whom we co-manufacture for that is asking us to create 'blending specifications' for the mixes that we blend and package in house for them. They aren't very sure what they are looking for and neither am I but the goal is to create something, a standard, to follow to compare our finished product to. We already have mix ratios for each batch but I am stumped at what else we can do. Looking for any ideas that you all may have!!
Thanks a ton 
Dear Allison,
I think they are looking for final specification for the blend you are supplying to them, that means the blend is finished product for you and raw material for them. Please get the blend tested for the nutritional value and physico chemical parameters along with microbiological parameters then you can prepare specification accordingly.
testing and Specification development depends on what type of blend you supply to them,,, for example we are procuring ragi malt from one of our co-packers and we asked them to give specification for the same and they gave spec with following parameters viz Appearance, taste, odour, solubility, pH, moisture content, protein, fat, ash, Total plate count, yeast and mould count, Ecoli, salmonella, etc
Thanks.
