Learning Outcomes
Learning Outcomes:
On the successful completion of this module, the student will be able to:

1.Demonstrate knowledge of the classification, identification, reproduction and growth of bacteria and microbes of relevance to the dairy industry.

2.Recognise and understand the effect of pathogens and food spoilage organisms in dairy products and explain methods used to control their growth. Apply food safety principles to the dairy industry.

3.Compare and contrast the microbiology of milk, butter, milk powder, casein and cheese. Interpret and monitor microbiological data as it relates to a range of dairy products.

4.Describe the principles of hygiene in a dairy plant and be able to operate and monitor cleaning in-place technology. Identify solutions to familiar problems encountered in the cleaning process.

5.Explain the sequences and operation of thermal processing in the dairy industry and the basics of quantitative thermal processing.

6.Evaluate the risks to the dairy industry of pathogens in product and the quality and monitoring processes required.
