Charles has an excellent pdf on post #10 on this thread http://www.ifsqn.com...lity-procedure/ that explains traceability
This area http://www.ifsqn.com...n-traceability/ has everything that was designated traceability when different topics were created
Looking through some of that may help a little.
I understand you have a lot of ingredients in yogurt manufacturing I used to have about 30-40 different ingredients that we used to make about 10 products...
One of the easiest ways of maintaining traceability within your plant is to use a batch sheet when you make a product. The batch sheet will have the name of the product, the day it was made, how much the shift is making, and all of the ingredients listed on it. Next to the ingredients there will be fillable areas next to it for the quanitity that the shift used and the lot code of that ingredient... typically the ingredient lot code comes from the supplier so they know what went into making that ingredient or when and where it was made (depending on the ingredient).
Product
Date
Time
Amount to make
Ingredients:
Name of ingredient amount expected to be used amount used lot code
Ingredient 1 250L XXXL (ingredient lot code)
Ingredient 2
ingredient 3
ingredient 4
Name of operator Signature
something like that is what I envision
You also have to record what packaging materials your using in packaging with a document so you can track what packaging materials were used on what products.
