Title / Demonstrate knowledge of cream products processing in a dairy processing operation
Level / 3 / Credits / 5
Purpose / This theory-based entry-level unit standard is for people carrying out milk products processing in a dairy processing operation.
People credited with this unit standard are able to demonstrate knowledge of: the characteristics of milk fat and the basic principles of good cream handling practices; the basic principles of the Fritz buttermaking process and product testing of butter; the basic principles of the 'direct from cream' anhydrous milkfat manufacturing process and product testing conducted on anhydrous milkfat; the basic principles and advantages of the Ammix process for buttermaking; and the sensory evaluation of cream products, in a dairy processing operation.

Please note

Providers must be granted consent to assess against standards (accredited) by NZQA, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.

Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards.

Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards.

Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMRs). The CMR also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
