Call for comment on thermolysin as a processing aid

Published

Food Standards Australia New Zealand (FSANZ) is calling for comment on an application to permit the use of the enzyme thermolysin as a processing aid.

Thermolysin (EC 3.4.24.27) is an enzyme produced by the Rokko strain of the microorganism Anoxybacillus caldiproteolyticus.

The application seeks approval to use thermolysin during the processing of a wide range of foods including dairy, eggs, meat and fish, to help break down proteins.

Our safety assessment found no public health or safety concerns with the proposed use of the enzyme.

To have your say about this application, visit the FSANZ Consultation Hub. Submissions close at 11.59pm (AEST) Thursday 3 July 2025.

What happens to my feedback?

FSANZ will consider all feedback received through this submission process before deciding on whether to approve the application. 

Submissions will be published to our website as soon as possible at the end of the public comment period.
