Improved Sugar Production by Optimizing Planetary Mill Pretreatment and Enzyme Hydrolysis Process

Table 2

Comparison of the pitch pine sawdust waste crystallinity after 20 minutes of planetary milling in an acetate or citrate solution.

	Untreated	Acetate	Citrate
Crystallinity index (%)	52.5 ± 0.9	31.7 ± 0.3	36.5 ± 5.1
Relative crystallinity index^1	1.00 ± 0.02	0.60 ± 0.01	0.70 ± 0.10

Relative crystallinity index: crystallinity index after planetary milling/crystallinity index of untreated sample.
