List of the 6 biomarkers of foie gras technological yield identified with the metabolite method.

Var ID (Primary)	VIP-valuesε	BH p-valuesζ	R2
Glucose	2.8	<0.001	0.39
Lactate	4.06	<0.001	0.50
Alanine	1.43	<0.001	0.24
Taurine	1.51	<0.001	0.28
Threonine	1.72	<0.001	0.49
Guanidinoacetic acid	1.04	<0.001	0.39

^εThe PLS model to describe the technological yield with metabolite data was plotted. The first latent variable enabled to separate the fatty livers in function of the liver weight. The metabolites with VIP superior to 1 were selected. The VIP of the metabolite was indicated.

^ζFor each biomarker, the effect of their relative concentration on the technological yield was tested by a linear model with R software, and the p-values were corrected with the Benjamini-Hochberg procedure and named BH p-values.
