STATISTICS

This package analyses instrumental data (Production and physical and chemical criteria, ...), with product
comparison graphics, analysis of variance, ...
Statistical analysis evidences also correlation with SENSORY ANALYSIS.
Product analysis with instrumental results
Operating process management by the production data follow up with the sensory non
conformity links
Evidence of the formula optimum in regard with a sensory analysis product profile target.
Analysis Preparation

The Systeme suggests to enter the product names, sample names, then the variable names.
Data Entry


Data Entry is equivalent to a spreadsheet as displayed on the previous screen, or data can be imported
using various data import formats.
Calculation
Data analysis is very large and various with:
Data description, with various distribution statistics with means, standard deviation,
confident intervals, …
Data structure analysis with Analysis of Variance including normalisation studies, and
mean comparison tests (LSD, Newman&Keuls, Duncan…), with graphs, and thus, in complete or
incomplete factors.
Multidimensional Analysis with principal Component Analysis, for example, or classifications
as Ascendant Hierarchical Analysis, ...
Links between Sensory Analysis description and Instrumental Analysis are possible with
joint multidimensional Analysis…





Quality Control: Production and Sensory Analysis
A joint analysis between production data and Sensory Analysis on the same samples in time analysis
will provide indicators and correlations between production parameters and changes on Sensory aspects.
Sensory aspects could be defined by visual, olfactory or gustatory descriptors.
This analysis will be then able to precise the main production points on which to focus in order to avoid
any change on the product sensory profiles.
Production data follow up
This analysis displays watching and control limits based on the production data follow up
These limits will be useful to define the tolerance limits to accept or to reject new production batches.
You can display the various distribution indicators:
|
Value regression, in order to identify a drift, if the straight line is not horizontal
|
|
Watching limit, for the points outside of the 95% confident interval
|
|
Control limit, for the non-conformity points, outside of the 99.8% confident interval.

Joint Analysis: Recipes and Sensory Analysis
A first step is to enter the recipe data of 5 to 6 or more products.
Second, is to get a Sensory product profile for each of these products
Then, a joint data calculation will identify correlations and links between these two types of data
(Recipe in one hand, and Sensory, in the other hand).
It will be then possible by introducing a new desired sensory product profile to know the calculated
recipe of this new product.
A very simple example below can evidence links between recipe data: Amount in Hony, Sugar, fruits, chocolate
and pH with Sensory descriptors as caramelised taste, fruity, bitter, sweet, or then chocolate.


The system will then model a new product: Chocolate yogurt (Yaourt chocolat)
This analysis has for aim to gather and to link Sensory Analysis and Recipe Data in order
to facilitate and to speed the product development operations.

The recipe data can be extracted automatically from the other system called RECIPE developed by the
Hamilton Grant Company.
MIX PLANS

The system suggests Experimental design according the mix types (I,II,III,IV) and the element number
with their levels, in order to issue optimum formulation graphics.
Technical optimisation of a mix formulation in comparison of an experimental answer:
stability, viscosity, texture, preference, ...
Price optimisation by a different mix of lower price elements.
Mix definition and Experimental Design


Entering the mix components, up to 4 maximum and their constraints
(lower level, and upper level, in the mix analysis field), allow the definition of the mix,
but also implies the mix type:
. Type I, if doesn’t exist constraints on the components: From 0% to 100%, and no solvent
. Type II, if some minimum levels are higher than 0%, and no solvent
. Type III, if some minimum levels are higher than 0%, some maximum levels are lower than 100%,
and no solvent
. Type IV, if most of the mix is constituted of solvent (higher than 90 %, for example).
At the end of the component data entry, and the saving with a mix number, it is then possible to
take knowledge of the suggested experimental design.
Data entry of the experimental data
The data entry of the experimental data is asked according the suggested design, in order to test
the model validity (linear model, quadratic model, other...).


After validation, results are displayed
with a answer surface graph and the model coefficients.


FORMULAS OPTIMISATIONS

Starting of formulation critical factors to get a ‘target’ answer: stability target,
sensory product profile, or also any other objective, the system suggests experimental design.
Graphics display answer surfaces in order to identify optimums, and the experimental model.
Identification of factor links for an experimental answer
Experimental model to search the best technical mix or the best price for a processus or a
formulation.
This module allows to enter very easily the main factors influencing experimental results in order
to suggest an experimental design, and consequently to identify the laws at the basis of the process
to optimise.


Then, experimental design are automatically available to prepare experiments: A three complete factors
model with linear and/or quadratic model is displayed on the previous screen.
According protocol optimisations, experiences with 2 to 15 factors can be calculated.
Example data entry with the three factors previously quoted is doing as follows:

A difference value between experimental result and calculated value is asked to test the model validity
according various possible laws.
Calculation can then graph iso-answer curves according the different considered factors:


Additional results are displayed as model coefficients, for example, if this one is accepted.


COST OPTIMISATION

Based on the ingredient costs, the integration limits, and the making constraints, the System
will suggest the least expensive formula meeting these points.
Cost optimisation by an optimum arrangement of ingredients
It is possible to enter ingredient names and their costs.
Then, considering the integration limits of these ingredients, and according
to the various product constraints, the System will suggest the best solution
at the lowest price.
Starting from a simple example:
A big delicatessen company needs to develop its sausages production and to improve its raw materials:
Its R&D Department informs it is possible to put:
|
5 to 10% of animal fats at 0.8 euros/kg, with 100% of fat.
|
|
20 to 30% of beef at 2 euros/kg, with around 15% of fat
|
|
40 to 60% of pork at 0.9 euros/kg, with around 25% of fat
|
|
10 to 20% of shoulder of pork at 1.5 euros/kg, with around 10% of fat
|
|
5 to 15% of vegetal fats at 0.3 euros/kg, with 100% of fat.
|
It is also known to not excess 27% up to 33% of total fats in the finished products to meet the marketing
and legal specifications.
The question is then to know the optimum ingredient percentages to produce this sausage at the best price,
in the definite limits of fats
Data entry is esily done as follows:


Results are then the following ones:


Steps between the lower and the upper fats limits can be displayed in numerical results or in graphs:


So, we can observed that the minimum raw materials cost can vary from 1,24 up to 1,10 per kg, according
the fats constraints, the System is giving also the percentages of each ingredient.
The System can optimise, with sophisticated techniques called Simplex method, raw material costs, with
changes in percentages or by substitution of ingredients.
