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

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

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

2.The role of Internet

• Internet,the living rooms of the world

(simple electronic billboards, Ads,..)

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

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

3. Availabe Sofwares

WebSPC• a secure web application designed to share

statistical process control information

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.

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).

• 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

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

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

• 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

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

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

• 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

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

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

6. An example

• Allows users to perform sensory QC on products using trained QC assessors

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

6. An example

• Create project template for each product type.

- This template includes:

The questionnaire, panelists and quality ranges for each attribute.

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

• 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

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

6. An example

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

• 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

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”
