Table 2 Water and oil absorption capacities of freeze-dried soybean powders with pre-treatments (unit: mL/g)

Soybean type	No treatment	Steamed soybean	Puffed soybean	Air-fried soybean
Water absorption	2.38±0.031)^c2)	2.66±0.02^b	2.82±0.03^a	2.80±0.06^ab
capacity	2.38±0.031)^c2)	2.66±0.02^b	2.82±0.03^a	2.80±0.06^ab
Oil absorption	2.12±0.03^ab	2.00±0.01^c	2.14±0.02^a	2.06±0.01^bc
capacity	2.12±0.03^ab	2.00±0.01^c	2.14±0.02^a	2.06±0.01^bc

All values are triplicate determination. Results are shown as mean±SD.
Means with different letters in the same row are significantly different (p<0.01) by Duncan’s multiple range test.
