Hi Kdaly,

 

As you know, IQF Food = Individually Quick Frozen Food

 

https://en.wikipedia..._Quick_Freezing

 

afaik, only the first word has a (self evident) quantitative definition although industrially the terminology "frozen food"  is typically associated with food having been processed and stored such that the product core temperature ideally attains/maintains  a temperature as least as low as -18degC (approx. 0degF).

 

-18degC is afaik mainly, but perhaps not entirely, a convenience reference point, eg -

I speculate that the terminology IQF originated as a process  time contrast to block frozen food (B/F), the latter typically being  output from a non- "quick" freezing process (eg hours).and not  yield individual frozen pieces.

 

This link implicitly suggests an (older) alternative processing distinction  -

Googling  <<definition individually quick frozen iqf>> gives 70,000 hits to browse  through. :smile:

 

PS - some further temperature confusions discussed here -
