A quick google search shows that it's a protein digestibility assay of some kind, and will also show several labs that do it. Try an international lab group like FSNS or MXNS, they likely have a local lab. https://www.merieuxn...ety-and-quality

I've used Reading Scientific Services (https://www.rssl.com/) set up bespoke methods where I haven't been able to find them offered as a standard test by any of the commercial labs.

I'm a little surprised by Campden's response, as I've also done work with them that involved setting up a method specifically for our requirements, so it might also be worth asking them if it's something that they can do.
I couldn't see it listed on the Eurofins or ALS sites but worth giving them a call/email too, given the scale of their facilities in the UK.

Hi, Thanks.

 

I have checked with Eurofins and ALs, INtertek who doesnt offer this test.

 

Is there any specific name for the test. I am asking PDCAA - Protein digestibility corrected amino acid.

 

Thanks

It might be described as PDCAAS (protein digestibility-corrected amino acid score) but that shouldn't make a difference to your enquiries. I think the main challenge is that it isn't a common test so likely not set up by many of the commercial labs, hence people like RSSL/Campden perhaps being the most likely options.

Starting to understand - from SQFConsultants article....

There are some drawbacks when using the PDCAAS method, including:

  • The long turnaround time for results: 2-3 months.
  • The average cost per test.
  • The common reliance on rats as test subjects, which raises ethical concerns for some food manufacturers and concerns over whether a rat’s digestive system reflects that of a human’s correctly.

Hello Everyone,

 

Is there any lab in UK would do the test for PDCAA.

 

I have checked with CAMDEN BRI, EUROFINS,INTERTEK,RSSL and ALS  who does not offer this test.

 

Any suggestion which lab can offer this test.

 

regards
