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
![Page 4: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/4.jpg)
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
![Page 5: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/5.jpg)
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

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
![Page 7: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/7.jpg)
2.The role of Internet
• Internet,the living rooms of the world
(simple electronic billboards, Ads,..)
![Page 8: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/8.jpg)
2.The role of Internet
• A benefit always have risk attached.• battle between:
efficiency > < simplicity
complexity > < comprehensiveness

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

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
![Page 11: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/11.jpg)
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
![Page 12: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/12.jpg)

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).
![Page 17: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/17.jpg)
• 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?
4. Development of a sensory quality program
![Page 18: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/18.jpg)
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
![Page 19: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/19.jpg)
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
4. Development of a sensory quality program
![Page 20: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/20.jpg)
• 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
4. Development of a sensory quality program
![Page 21: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/21.jpg)
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
![Page 22: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/22.jpg)
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
5. Implementing a sensory QC system
![Page 23: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/23.jpg)
• Both CCFRA and the Leatherhead Food Research Association have trained many companies
• “How to develop sensory quality systems tailored to their needs”
5. Implementing a sensory QC system
![Page 24: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/24.jpg)
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.

5. Implementing a sensory QC system
![Page 26: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/26.jpg)
6. An example of a computerized sensory QC system
• A collaborative project between CCFRA and Compusense
Þ a general solution that can automate the sensory QC process
Compusense QC1
![Page 27: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/27.jpg)
6. An example
• Allows users to perform sensory QC on products using trained QC assessors
![Page 28: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/28.jpg)
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
![Page 29: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/29.jpg)
6. An example
• Create project template for each product type.
- This template includes:
The questionnaire, panelists and quality ranges for each attribute.
![Page 30: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/30.jpg)
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
![Page 31: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/31.jpg)
• 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
6. An example
![Page 32: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/32.jpg)
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
6. An example
![Page 33: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/33.jpg)
6. An example
![Page 34: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/34.jpg)
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
![Page 35: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/35.jpg)
• 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.
6. An example
![Page 36: Qlcl bao cao](https://reader038.vdocuments.mx/reader038/viewer/2022103116/558979e2d8b42a7b448b4571/html5/thumbnails/36.jpg)
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”
