<strong>Specific</strong> <strong>Sensor</strong> <strong>Array</strong> <strong>For</strong> <strong>Taste</strong> <strong>Screening</strong><br />
<strong>with</strong> ASTREE Electronic Tongue<br />
Instrumental Quantification of <strong>Taste</strong> Attributes<br />
Main features<br />
<strong>Specific</strong> sensor array directly adaptable on existing<br />
ASTREE Electronic Tongue<br />
Dedicated to Food & Beverage applications<br />
Relative ranking of attributes intensity<br />
on a 0 (low level) to 12 (high level) scale<br />
Automated method for the evaluation of taste attributes<br />
in products<br />
Sourness, saltiness, umami: measured directly from 3 different sensors<br />
Other tastes including sweetness and bitterness: measured by<br />
applying standard addition methodology<br />
<strong>Taste</strong> related sensor selection obtained for each sample analyzed<br />
<strong>Specific</strong> representations available for easier reading and interpretation<br />
Global radar plot showing all sensors measurements<br />
1-dimension scales for each taste attribute quantification<br />
2-dimension graphs based on 2 selected taste axes<br />
Current multivariate statistics data processing still available<br />
ASTREE Electronic Tongue<br />
(<strong>Alpha</strong> <strong>MOS</strong>)<br />
A dvantages<br />
Direct ranking based on taste attributes, no need for sensory panel input<br />
<strong>For</strong>mer training phase of the Electronic Tongue not required anymore<br />
Simplication of results reading<br />
Ranking of 6 apple juices based on sourness intensity
A pplication: taste characterization<br />
Objective: compare 4 different tomato juices (TJ1 to TJ4) based on their taste<br />
attributes (sourness, saltiness, umami = tomato taste and sweetness)<br />
Equipment: Astree Electronic Tongue <strong>with</strong> taste screening sensor set<br />
Direct measurement of sourness, saltiness and umami<br />
<strong>For</strong> sweetness quantification, glucose (main sweet component in tomato) is used as a standard<br />
Analytical conditions<br />
Results<br />
Number of repeats : 3 replicates / sample Acquisition time: 2 min<br />
Sample volume: 25 g Cleaning time : 10 sec<br />
Time per analysis: 3 min Total analysis time : 90 min<br />
Standard addition method: 5 glucose concentrations (0.1, 0.25, 0.5, 1, 2 % w/w) added to TJ1<br />
Sample TJ1 is the most different; the other 3 samples are<br />
showing similar characteristics for saltiness and umami.<br />
Sample TJ1 presents the highest score in sourness,<br />
saltiness and umami but the lowest score in sweetness.<br />
