[0034] Embodiment 1 Determination of the color parameter range of gardenia decoction pieces

[0035] 1.1 Instrument and measurement conditions

[0036] Instrument CM-5 spectrophotometer (Konica Minolta Co., Ltd., Japan), equipped with Spectric-Magic NX workstation.

[0037] Measuring conditions The light source is a pulsed xenon lamp, the light source is D65, the standard observation angle is 8°, and the illumination aperture is Φ3mm. The instrument error ΔΕ*ab is within 0.6; the measurement wavelength range is 360-740nm; the repeatability standard deviation ΔΕ*ab is within 0.07; the inter-instrument standard deviation ΔΕ*ab is 0.15. The lighting system is SCI (specular componetnt included) reflected light mode with specular light and specular componetnt excluded (SCE).

[0038] 1.2 Pieces

[0039]Gardenia decoction pieces (34 batches of raw products, 34 batches of stir-fried products, 36 batches of burnt products, and 32 batches of charcoal products) were collected from major

[0089] Correlation analysis of embodiment 2 Gardenia pericarp and seed color

[0090] Since the original color data of the peels and corresponding kernels of gardenia decoction pieces (raw gardenia, fried gardenia, burnt gardenia, and gardenia charcoal) did not satisfy the normal distribution, the Spearman's rho correlation coefficient of single factor correlation analysis was used to explore Correlation between internal and external colors of different decoction pieces of Gardenia jasminoides. See Table 14 for the correlation coefficient results between the kernels (L*n, a*n, b*n) and peel color variables (L*w, a*w, b*w) of each decoction pieces of Gardenia jasminoides.

[0092]

[0093] The results showed that the Spearman's rho grades corresponded one-to-one between the three sets of color parameter parameters (L*w—L*n, a*w—a*n, b*w—b*n) of raw gardenia pericarp and correspon

[0095] Embodiment 3 The establishment of the mathematical discriminant formula of processing degree of Gardenia jasminoides

[0096] In order to establish a mathematical model of the processing degree of decoction pieces. Based on the reference value range of each grouping of Gardenia (raw Gardenia, fried Gardenia, burnt Gardenia, and Gardenia Charcoal), the collected color data of different pieces of Gardenia were analyzed using the typical discriminant analysis (Discriminant) method. Discriminant function - Bayes (Bayes) discriminant rule to establish a mathematical discriminant function model for judging the degree of processing of different gardenia decoction pieces, and then use the ordinary method (Original) and cross-validated (Cross-validated) to analyze each color data of each gardenia decoction piece authenticating.

[0097] According to the original color data collected from different decoction pieces of Gardenia, through discriminant analysis, the mathematical discri
