1. Manufacturing How are products made in the factory?
What is Quality Assurance and Quality Control?

2. Methods of manufacturing
One off production – only making one item to the customers specification ie. Wedding cake.
Batch production – making identical products when a certain quantity is required cheese pasties followed by 1000 ham and onion pasties. Products can be made according to demand.
Mass production – the process is divided into stages. Workers learn the part of the manufacturing process and become very skilled. The production line can be varied from day to day. E.g. Vanilla Swiss Roll
Continuous production – A production line is set up and produces good continuously, often 24 hrs a day and 7 days a week – e.g. coca cola cans

5. How can a factory maintain quality?
Quality Assurance – this is concerned with the overall standard of quality of the factory processes. It involves everyone in the business, from lab technicians to clerical staff. It should include:-
Raw material specifications
Suitability of the suppliers
Recipe information
Manufacturing methods
In-put, process specifications and feedback for control
Appropriate storage
Distribution and recall control systems

6. Quality Control
This is part of the quality assurance. It involves sampling and testing a product as it is being made, to ensure it fits within the designated tolerances. QC can take the form of:-
Weight checks- under or over-weights are rejected.
Visual checks for checking condition of food, seal etc.
Computer monitoring for colour / shape
Organoleptic – tasting and smelling, sensory testing on delivery and final product.
Inspection for quality to match the specification
Chemical analysis – samples tested for chemical contamination and nutritional analysis.
Microbiological analysis – testing for bacteria.
Temperature – at various stages from delivery to cooking temperatures, often using probes.
Metal detectors – identify any metal from machinery etc.

7. TQM – Total Quality Management JIT - Just in time stock control
This involves all workers in the quality assurance procedures. Each stage of the manufacturing process is checked by the next section on the line.
JIT
This is a system which orders stock to arrive for when and where it is needed.
It prevents the unnecessary use of storage space and staff required to monitor the safe storage of commodities
