Bioprotection on Chardonnay Grape: Limits and Impacts of Settling Parameters

Table 3

Tristimular coordinates (L, a, b) of musts after settling.

Modes	L	a	b	Overall color difference (ΔE)	Difference with the reference S + 12
S + 7	64.55	9.47	42.83	78.04	0.87
S + 12	63.72	9.57	42.48	77.17	0.00
S + 18	63.81	9.07	41.64	76.73	−0.44
L + 7	65.62	8.87	42.47	78.66	1,49
L + 12	83.12	2.74	30.24	88.49	11,32
L + 18	82.02	1.66	24.98	85.75	8.58

Note The color difference was calculated using the following formula: ΔE = ((ΔL)² + (Δa)² + (Δb)²)^1/2. The reference mode is in bold.
