PURPOSE OF THE UNIT STANDARD 
A person credited with this unit standard is able to:
  • demonstrate knowledge of starter cultures for fermented dairy product manufacturing
  • demonstrate knowledge of the mechanism of coagulation during fermented dairy product manufacturing,
  • demonstrate knowledge of the methods of coagulation for fermented dairy product manufacturing,
  • coagulate a dairy mixture for fermented dairy product manufacturing.

    This unit standard is for anyone who has to produce a coagulum from a pasteurised and standardised dairy mixture for the manufacturing of a fermented dairy product.

    This unit will contribute to the full development of the learner within the dairy manufacturing environment by providing recognition, further mobility and transportability within the field of manufacturing and assembly. The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and upliftment within the dairy manufacturing and processing environment.

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Description of required skills:

    Knowledge of bulk starter preparation.
    Representative sample taking for quality control purposes. 

    UNIT STANDARD RANGE 
    The scope of this unit standard is for anyone who has to produce a coagulum from a pasteurised and standardised dairy mixture for the production of fermented dairy products.

    In the context of this unit standard, fermented dairy products include yoghurt, buttermilk, maas, sour cream and smooth cottage cheese, but exclude chunky cottage cheese.

    The level assigned to this unit standard is appropriate because the process requires a wide range of technical skills and offers a considerable choice of procedures. A broad knowledge base incorporating some theoretical concepts, analytical interpretation of information, informed judgement and a range of sometime innovative responses to concrete but often unfamiliar problems are employed. The application of this unit standard is to qualify the person for certification in advanced trade and technical occupations.

    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
