    Joan,   Just an FYI. The reminder emails are helpful for those of us that get ridiculous amounts of emails.

    Joan,   One comment from Schiff;  I see you are including krill oil in the requirement for testing.  We do not test krill oil for rancidity and/or p anisidine because we found that the astazanthin interferes with the test.  In addition, our krill oil softgel capsules contain vanillan which also interferes with the test.  Over the years we have not had much success with testing for rancidity/peroxide for various reasons in either the krill or fish oil.  Most notably is that the peroxides are short lived, especially if subjected to heat, and therefore the test may indicate a low level of peroxide but does not indicate how much oxidative degradation may have already occurred where the peroxide has further broken down.  The other reason that this is less of an issue with krill oil is that the astazanthin is an anti oxidant which helps to prevent oxidative degradation in the oil.   I would not be in favor of including krill oil on the list.   Best regards,   Vince Rocco   From: ds_jc@xxxxxxxxxxxxxxxxx [mailto:ds_jc@xxxxxxxxxxxxxxxxx] On Behalf Of Douglas Mackay Sent: Wednesday, December 05, 2012 8:18 AM To: Hoffman, Joan; ds_jc@xxxxxxxxxxxxxxxxx Subject: RE: [ds_jc] REMINDER: Table of Oils for Rancidity Testing -- please provide feedback by December 7, 2012   Joan,   Just an FYI.

    While it doesn't help today, my understanding is that the FCC Krill Oil Monograph, to be published in the summer of 2013, will include a yet to be publicly disclosed test for oxidation.
