120397  Evaluate the quality of a food product in terms of its titratable acidity  Level 2  NQF Level 02  4   

PURPOSE OF THE UNIT STANDARD 
A person credited with this unit standard is able to
  • demonstrate knowledge of the determination of titratable acidity of a food or beverage product
  • prepare for determining the titratable acidity of food or beverage product
  • determine the titratable acidity of a food or beverage product under laboratory conditions
  • report on the quality of a food or beverage product in terms its titratable acidity
    This unit standard is for anyone who needs to determine the titratable acidity of a food or beverage product under laboratory conditions.

    This unit will contribute to the full development of the learner within the food or beverage 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 food or beverage manufacturing and processing environment.

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Required skills or knowledge on:
    Laboratory safety
    Handling of chemicals and general laboratory apparatus.
    Knowledge of basic physics and chemistry principles NQF 1 

    UNIT STANDARD RANGE 
    The scope of this unit standard is for anyone who has to determine the titratable acidity of food or beverage product under laboratory conditions. This unit standard can also be applied for determination of the acidity of cheese whey, culture media and other chemicals and liquids used during manufacturing and quality control of food or beverage products, e.g. cleaning agents and boiler water.

    In the context of this unit standard milk refers to raw or pasteurised milk, while a food or beverage product includes any in-line or final food or beverage product.

    The level assigned to this unit standard is appropriate because the process is moderate in range, established and familiar and offers clear choices of routine responses. The learning demand employs basic operational knowledge and readily available information. The application of this unit standard is to qualify the person for certification in sub-trades..
