Summary module description:
This module serves as an introduction to food processing and food texture/mouth-feel, and includes the physical properties of food systems and the quantitative principles and underpinning processing operations. In this module important food processing and food textural quality defining parameters and principles will be introduced. This module is intended to be a prerequisite to study food processing sciences and physicochemical aspects of food quality and storage.

- Explain the principles of selected physical aspects of biological systems and to understand their role in transporting, processing, storage and analysis of such materials.
- Improve numeracy, quantitative and laboratory skills by integrating lectures with practical work and numerical problems in the subject area.
- Provide the building blocks for further courses in food processing and biotechnology.
- Understand the role of physical properties in food processing operations and food quality/mouth-feel assessment.
- Use experimental methods to determine physical properties.
- Use compositional data or reference sources to estimate physical properties.
- Provide examples of typical values for the main physical properties.

Assessable learning outcomes:
On completion of the module, students should be able to:
- identify key physical properties of foods which critically influence processing and mouth-feel
- Do simple numerical calculations related to mass and heat balances around individual food processes and process plants.
- state the units of relevant physical properties of foods in SI and other units and be able to convert from SI units to other practical units and vice versa.
- Perform simple laboratory experiments for determining selected physical properties and perform calculations to determine their values.
- Produce meaningful laboratory reports.
- Estimate some physical properties of food from food composition data.
- Food safety.

Additional outcomes:
The students would be able to appreciate the role of physical properties, in conjunction with chemical, biochemical and microbiological aspects, in determining food safety and quality.

Outline content:
Autumn term will review basic mathematical skills necessary to understand the material taught in Spring term. Autumn term will contain:
Real number system. Use of calculator functions. Units and conversions. Topics in basic algebra. Elements of co-ordinate geometry, straight lines and other graphs. Laws of indices. Logarithms. Simultaneous and quadratic equations. Derivatives. Elementary statistics, averages, probability distributions, hypothesis testing, data correlation, linear regression. Introduction to spread sheets, manipulating data sets using spread sheets, plotting graphs, correlating data and interpreting relevant statistics.

Spring term will contain:
Composition of biological materials and its effect on physical properties. Units and dimensions and dimensionless groups. Introduction to physical concepts such as velocity, acceleration, momentum, force, pressure, work, energy and power. Circular motion. Mass and energy balances, energy conversion processes. Size shape, density, porosity, specific heat, latent heat and, enthalpy. Introduction to rheological properties, fluid statics and hydrodynamics. Interfacial properties and optical, electromagnetic and electrical properties.
Summer term will contain:
Food processing practicals.
During the year, students will also be given the opportunity to obtain the level 2 Award in Food Safety for Manufacturing.

Global context:
The global context of the content covered in this module is food manufacturing including food processing, food formulation and food safety and quality – which are critical to ensuring food security.

Penalties for late submission:
The Module Convenor will apply the following penalties for work submitted late, in accordance with the University policy.

  • where the piece of work is submitted up to one calendar week after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for the piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
  • where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

  • The University policy statement on penalties for late submission can be found at: http://www.reading.ac.uk/web/FILES/qualitysupport/penaltiesforlatesubmission.pdf
    You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.
