3. Abstract
• Computer technology is changing rapidly
• Quality systems can be constructed from simple
programs through to sophisticated systems
• Provides an overview of the available tools, a
starting point for computerizing sensory QC

4. 1. Introduction
• Most research facilities have:
 Automated their collection of sensory data
 Connected it to statistical analysis
• Make management decisions
 The reduction in cost of hardware
 The widespread of personal computers
• Sensory Analysis can be used to make
management decisions

5. 1. Introduction
• Computers are merely tools, not a solution in
themselves
• “Automation of accounting systems improved
good accounting practices, but never created
good accounting by itself”
• It is only good when increase a benefit

6. 2.The role of Internet
• The information superhighway
Messages can be to any other connected device
on the planet
• The use of electronic mail, e-mail,has become
universal.
• The documents are attached in a common file
-> many viruses have been spread

7. 2.The role of Internet
• Internet,the living rooms of the world
(simple electronic billboards, Ads,..)

8. 2.The role of Internet
• A benefit always have risk attached.
• battle between:
efficiency > < simplicity
complexity > < comprehensiveness

9. 2.The role of Internet
• The simplest and most profound application
for QC is the electronic spreadsheet.
• Excel program dominates this market

10. 2.The role of Internet
The ability :
• create a record of responses
• accumulate data over time
• analyze the data for trends and report the
results graphically

11. 3. Availabe Sofwares
• There are many programs for quality that are
web-based
• The inexpensive or „„freeware‟‟ applications
have limited features
• The expensive applications are customized to
meet end user specifications

12. 3. Availabe Sofwares
WebSPC
• a secure web application designed to share
statistical process control information
http://www.hertzler.com/

13. 3. Availabe Sofwares
QualTrend
• Lets users get at any quality data from diverse
locations
• Transform critical data into key performance
indicators
• Production from several plants can be
compared and controlled simultaneously.

14. 3. Availabe Sofwares

15. 3. Availabe Sofwares
• NWA Quality Analyst Web :
(http://www.nwasoft.com)
• Quality Navigator:
(http://www.guardess.com)
• Statit e-QC:
(http://www.statware.com).

16. 4. Development of a sensory quality program
There have been several excellent publications
Including:
• the landmark publication of Munoz,Civille, and
Carr (1992)
• the textbook chapter by Lawless and Heymann
(1998).

17. 4. Development of a sensory quality program
• A similar systematic approach
• Guidelines that establish good standards of practice
for sensory QC
• Make a list of steps that are generic and academic
BUT
How do we put sensory quality control into
practice?

18. 4. Development of a sensory quality program
A presentation :
• Marianne Gillette ,Jacqueline,Beckley at the
Institute of Food Science meeting in 1992
Emphasized:
• the practical aspects of In-Plant Sensory
Quality Assurance

19. 4. Development of a sensory quality program
They recognized that for a sensory Q program to
work at the plant level
• Meet the sensory objectives
• Be acceptable to the management of the
company and its suppliers

20. 4. Development of a sensory quality
program
• Many of these points are of key strategic
importance in planning the implementation
• Extension of a basic sensory QC program into
other areas of quality

21. 5. Implementing a sensory QC system
A Sensory Quality Assessment system was
developed in the UK
 Supplier & retailer :
 Develop a standard, objective approach to
product sensory quality measurement

22. 5. Implementing a sensory QC system
Train a course to
• Develop an objective approach to product
quality measurement
• Understand how to achieve valid sensory
information
• Practice setting up the quality attribute scoring
system

23. 5. Implementing a sensory QC system
• Both CCFRA and the Leatherhead Food Research
Association have trained many companies
• “How to develop sensory quality systems tailored
to their needs”

24. 5. Implementing a sensory QC system
Training program
• The framework for the company
• Work with customers to implement a system
that monitors results
• A method for measuring improvement and
compliance.

25. 5. Implementing a sensory QC system

26. 6. An example of a computerized sensory QC
system
• A collaborative project between CCFRA and
Compusense
a general solution that can automate the
sensory QC process
Compusense QC1

27. 6. An example
• Allows users to perform sensory QC on
products using trained QC assessors

28. 6. An example
• The main Compusense QC software can be
installed and run from a network server
- Each QC project contains :
 1 product with a set of attributes
 ranges quality of each attribute

29. 6. An example
• Create project template for each product type.
- This template includes:
The questionnaire, panelists and quality ranges
for each attribute.

30. 6. An example
• When all results are collected, the data is
analyzed
• A QC grade is determined for each attribute
• Quality ranges are set when the project is made

31. 6. An example
• If the panelist scores the attribute in an
unacceptable range
• They can automatically be presented with a
comment question
• They provide further description, or a multiple
choice question

32. 6. An example
o The main task of Compusense QC:
• Analyze the panelist data according to the
defined quality ranges
• Render a quality decision or grade for each
attribute

33. 6. An example

34. 6. An example
The QC Manager‟s role is:
• Review the individual attribute grades
• Evaluate which attribute grades have more
weight in the overall product quality
• Enter an overall QC decision for the product

35. 6. An example
• MORE DETAILS :
+ The data can be exported to other programs
+ The data collected by each of the panelists
 for each of the attributes
 kept as a record of the sensory evaluation.

36. 6. An example
+ The data from individual batches
 accumulated in a database
 be able to analyze trends over time.
+ “Scaled for large and small enterprises and
allows continuous improvement and
development”
