DC	13.07	0	18.62	29.89	38.42
AAP0	18.26	3.06	14.62	27.06	37.00
AAP1	19.00	5.57	11.67	26.54	37.23
AAP2	19.15	6.02	11.31	26.46	37.07
AAP3	20.28	8.95	8.03	25.52	37.22
Pure COM	13.33	0	19.18	30.13	38.36
Pure COD	21.95	0	17.07	26.83	34.15

¹The weight loss of stage II refers to the decomposition of polysaccharide absorbed in the crystal, that is, the percentage of polysaccharide absorbed in the crystal.
