Hello fellow Food Safety Folks!
We sell a confectionary product that is heated in a kettle to an internal temperature of 228°F and then is cooled in a temperature controlled room. After it is cured, some of it is turned into rework, where it is then reused the next time that product flavor is made and sometimes it is not all used that same day. Whatever is leftover is put into the freezer for another day or just thrown out. The issue I have been wondering about, is if that next batch was made with rewor also becomes rework, how long can/should we continue reworking product which has been made with multiple lots of rework? As a product made with peanut butter and dairy, I worry that with the limited shelf life, it might cause micro issues and/or shorten the shelf life of the finished product after so long.
I hope this makes sense, I struggle to wrap my head around it!
Any advice, concerns or thoughts are very welcome!
