Caustic Soda in Food Production

Hi all,

My name is Akhil Nair. I am working as a QA Technologist. I am working on a project of calculating consumption of caustic soda (1.4%). during the production of pretzelized chips.

Please comment with your inputs.

In my opinion, theoretical chemistry is not valid for something like this.

You may find a formula that estimates the amount of lye in your chips, but the only way to know is through real-life testing.

I recommend finding a laboratory in your area that specializes in food analysis.

They will be able to take a sample of your chips and determine how much caustic soda remains in a serving.

Titrations will need to be completed. This can be a pretty difficult process.

It is likely beyond the scope of most food facilities. I am not aware of any test strips or other easy processes.

Best to let the chemistry professionals handle this one. Especially since too much caustic lye can be dangerous to customers.

Good luck!
