[Ask ] Lot-to-lot?

[mimic2002 (蘋果魂)]

There's a problem here and hope you guys can give me a hand.

The sentence is as the following:

....although MSG is a defined ingredient, analytically undetectable

lot-to-lot performance variation leading to process unreliable were observed.

Ok, I don't know what "lot-to-lot" meant.

Please give me a hand.

thank you so much.
