Do you spend enough time on food safety and quality improvement?
Has anyone ever heard of Quality being head of Operations as well?

Not something I've worked in but I suspect Brix (sugar) and pH will be important.

Thanks GMO. Yes I also found brix, Ph, acidity.

In addition to the parameters quoted, I would add organoleptic qualities such as colour and flavour. I worked with Tetra pak juices in the 90s - and orange juice particularly gets dark and tastes poor after 6 months. Also, Vitamin C needs to be measured near the end of the shelf life to ensure it is still present in the stated quantities. Apple Juice had a much better shelf life - around 12 months IIRC. Pineapple like Orange was subject to darkening.
Hope that helps
Dear Sujit,
Assuming that you are doing commercial sterilization, other QA parameters of importance are online checks for pack integrity(dye test, tear test etc), batch codes, Expiry date codes as well as shelf life simulations through incubation(if UHT process is used). You should also evaluate indicative microbial load of the finished product to ensure sterility is achieved.
I hope this suffices.

Hi Sujith,
We are only analyzing for Brix, Acidity, pH, and specific gravity.
Microbiological wise we are testing for
>APC
>Total coliforms
>E coli
> yeast and moulds

Food Safety boy,
How are you checking specific gravity ?. Can you give me some values for different juices.
Warm regards,
Sujit
