PURPOSE OF THE UNIT STANDARD 
This unit standard is for anyone who has to determine the activity of a starter culture.

A person credited with this unit standard is able to:
  • Demonstrate an understanding of determining starter culture activity.
  • Prepare for determining the activity of a starter culture.
  • Determine the activity of a starter culture.
  • Report on the activity of a starter culture in terms its pH or % titratable acidity.

    This unit standard 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:
  • Communication and mathematical literacy at NQF Level 2.
  • pH determination OR titratable acidity determination.
  • Knowledge of introductory dairy microbiology. 

  • UNIT STANDARD RANGE 
    In the context of this unit standard, a starter culture refers to a culture intended for the production of fermented dairy products. It includes all wet cultures and excludes direct vat inoculation (DVI) cultures.

    The results of the activity test are interpreted and a conclusion is drawn on the suitability of the starter culture for the production of fermented dairy products. 

    ASSESSMENT CRITERION 4 
    Deviations from the specifications for the activity of the starter culture are explained according to standard dairy principles. 

    ASSESSMENT CRITERION 5 
    The importance of accurate documentation is explained according to quality assurance principles.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    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.
