I am working in a low risk Food Manufacturing Company mixing powdered ingredients in a Blender and packing it as a Green Tea Lattes or Green Tea Mints by pressing the mixed products using tablet press.
I am have some difficulty in determining the upper limit for our products test results such as TPC, E. coli, Coliform and Yeast/Mold. Since we do not know the appropriate limit for our products, we determine the limits for TPC, Coliform and Yeast/Mold to be < 10 cfu/gm, while the E. Coli must be Negative. Since some of our raw materials have a rather high test results, we hardly able to get the test results that we want.
Is there a specific upper limit for green tea mints and lattes for those tests? or how can we determine the limits for them ?
I still don't have much experience in this field of work (Quality Control and Food Safety) so if you can help me because I can't find the answers in the internet.
