Extraction and Characterization of Cellulose from Broccoli Stems as a New Biopolymer Source for Producing Carboxymethyl Cellulose Films

Table 2

Thickness of CMC films made from 2, 4, and 6 g/100 mL CMC solution with glycerol (10-30% ( based on CMC)).

CMC concentration (g/100 mL)	Glycerol addition (g/100 mL (10-30% based on CMC))	CMC films thickness (mm)
2	0.2	^ab
	0.4	^b
	0.6	^ab
4	0.4	^b
	0.8	^ab
	1.2	^b
6	0.6	^a
	1.2	^ab
	1.8	^a

Note: values are given as (). Different letters a and b in superscript interpreted significant differences () between CMC films from different forming conditions.
