Conducting polymer analysis tests of the capability of the AromaScan A32S e-nose to identify and discriminate between good-flavor vs. off-flavor catfish meat cores.

Trial	Meat Type	n	Correctly Identified 1	Indeterminant 2	Unknown Determination 3	Aroma Class Match 4
1	Off-flavor	10	100.0	0.0	0.0	98.2
	Good-flavor	10	100.0	0.0	0.0	98.5
2	Off-flavor	10	100.0	0.0	0.0	98.8
	Good-flavor	10	80.0	20.0 (65.8)	0.0	95.3
3	Off-flavor	20	80.0	15.0 (67.0)	5.0 (51.2)	90.7
	Good-flavor	10	100.0	0.0	0.0	97.3

¹Percentage of catfish meat samples that were correctly identified.

²Percentage of unknown catfish meat samples for which a percentage match to a single aroma class was not high enough to make a clear identification. Values in parentheses indicate the mean percentage match determined from among all samples placed into this determination category.

³Percentage of unknown catfish meat samples for which data from the sensor array could not assign a match to any aroma class. Values in parentheses indicate the mean percentage match determined from among all samples placed into this determination category.

⁴Mean percentage match of unknown catfish meat core samples to the correct aroma class identity.
