Table 2. Relationship of the integral spectral peak areas and average absorbance responses with the respective aflatoxin concentration at 1,062–1,000 cm⁻¹ ATR-FTIR spectral wavenumbers.

Type of solvent	Peak area (Y) and concentration (×)		Average absorbance (Y) and concentration (×)
Type of solvent	Regression equation	R ²	Regression equation	R ²
75% MeOH	Y = 0.2151× + 4.8405	0.9372	Y = 0.0049× + 0.1	0.9064
ACN	Y = 0.1275 + 11.1450	0.8964	Y = 0.0028× + 0.3098	0.9283

Note: p-value in all the four regressions is less than the significant level (0.05).
