How to check the core temperature of IQF items

Hi All,

Ours is a frozen RTC culinary sauce manufacturing unit. We have two type of items.

1. Frozen Mediterranean sauces ( cube shaped -8gm/ cube-- same like Cadbury candies)

2. Asian sauces ( pouches of various sizes ranging from 85 - 180 Gm/ pouch) 

How to check the core temperature of these items. 

is by 1. penetrating into each cube/ pouch

         2. or keeping the thermometer probe between the products

All advises appreciated on which method to follow.

Hi Sawad,

Are they both frozen, packed finished product or ?

What is purpose of measuring temperature ?

Hi Sawad,

Yes for us they are finished product. We are doing bulk packing  & are sending to our own another facility, where it will be repacked into consumer packets with addition of other items . The final product is " Ready To Cook Frozen Meal Kit". 

The purpose of checking temperature is to ensure the products are achieving  proper temperature after freezing.

Hi Sawad,

Both methods assume that a constant product temperature has been established, eg in a cold store.

IIRC method 2 was offered by Codex presumably for convenience/non-destructive.purposes and shown to be useful for thermocouple sampling of container loads etc. It necessitates close contact between surfaces involved.

I suggest to try both methods on a few samples to validate the Procedures for situation of interest.
