Functional properties.
Foods have different functional properties which can be treated and combined. They can be finished to improve palatability. Additives are used for a number of reasons and can be artificial or natural.

Acidity and temperature.
Foods can be acidic, alkaline or neutral. The rate a food deteriorates is determined by acidity and temperature. Foods must be reheated properly to prevent food poisoning.

Food product development.
Social, environmental and ethical factors affect the foods that consumers buy. Diets can be affected by allergies and intolerances. A balanced diet is needed to prevent health problems.

Foodpackaging and labelling.
Food packaging protects and preserves food. A range of materials can be used for packaging, some of which are environmentally friendly. Labels carry information for the consumer. Some of this information is required by law.

Systems and practices Production systems consist of inputs,
processes, outputs and feedback. There are different scales of food production that require different kinds of equipment. CAD and CAM can be used to design, test, and monitor processes. Standard components can be used to speed up production. Safety is ensured through hazard analysis and critical control point checks.
